New publications on lysimeters available

Actual new results from the largest lysimeter in Europe – Agroscope Zürich Reckenholz/Switzerland – are published:

Germann, P.F., and V.Prasuhn. 2017. Viscous flow approach to rapid infiltration and drainage in a weighing lysimeter. Vadose Zone J. doi:10.2136/vzj2017.01.0020


Rapid infiltration and drainage in a free-draining weighing lysimeter are assessed with a viscous flow approach that is based on the concept of moving water films. The two parameters film thickness and specific contact area of the film per unit volume of the permeable medium together with the rate and duration of water input suffice to quantify viscous flow at the Darcy scale. The two parameters are deducible from wetting front velocities and water content variations during the passing of the film. Temporarily perching water tables at lysimeter bottoms are considered artifacts of the lysimeter method that may severely alter the biogeochemistry of the effluent. The viscous flow approach assesses the duration of water perching from drainage flow interpretation. Perching in the sense of viscous flow occurred at most 10% of the time during drainage flow. Drainage ceased completely during a 6-mo period that yielded only 46% of rainfall compared with the 30-yr average. During rewetting of the lysimeter soil, viscous flow applied to infiltrations of nine precipitation episodes, showing successive penetrations of wetting fronts shortly before the onset of drainage.

Due to climate change, agricultural production in Europe will be challenged by higher temperatures and shifts in precipitation distribution that will give rise to frequent summer droughts. An adaptation of agricultural systems to these changes requires detailed knowledge of crop water use characteristics. This study aimed to evaluate the
dynamics of evapotranspiration and water uptake in different crops under the typical edaphoclimatic conditions of Switzerland. Seven years (2009–2015) of high resolution lysimeter mass data including 70 lysimeter-by-year combinations were evaluated. The “adaptive window and adaptive threshold “-filter (AWAT) was used to determine
evapotranspiration (ET), precipitation (P), crop coefficient (Kc) and water use efficiency (WUE). Additionally, FDR sensors installed in the lysimeter soil core allowed recording the temporal dynamic of soil water extraction. The evaluation comprised grain maize, silage maize, rapeseed, sugar beets, winter barley, winter wheat and temporary ley. The AWAT filter was successfully used to determine lysimeter P that was inserted in the lysimeter water balance equation to calculate daily ET. It could be shown that the peak of daily crop coefficient coincided with the time of flowering for all flowering arable crops. WUE’s lay in the range given by standard literature, but daily crop coefficients were clearly higher than proposed by the Food and Agriculture Organization of the United Nations (FAO) which is partially due to an oasis and border effect of the lysimeters.
Years with limited water availability were characterized by a comparably low Kc. For example, rapeseed in 2011 and maize in 2015 showed substantially lower Kc values. In accordance with the reduced Kc, readily available water was totally removed down to soil depth of at minimum 0.85 m. The limited water availability led to significantly lower yields only in case of silage maize in 2015. These results show overall current water supply to be sufficient under Swiss conditions; however, if drought events like in 2015 become more frequent and even more intense, yield potential of typical Swiss arable crops will be limited by water availability.


UGT celebrates its 25th anniversary

Visit us at the EGU in Vienna – Booth No 18

From Monday, 24th to Friday 28th we are presenting our new EcoUnit at the EGU in Vienna. Visit us and get knowledge about the possibilities in your research. We have brought a full functional EcoUnit (Ecotron) to the show. The UGT team is looking forward to discuss your special need.

An EcoUnit is a measurement system to investigate ecosystem functions in the
soil-plant-atmosphere system under defined boundary conditions. Ecotrons are used to investigate processes within the soil-plant-atmosphere system as well as the interactions between the compartments. Ecotrons are lysimeter applications beyond the investigation of only soil processes and thus the generic term for lysimeter applications of all kinds.

idivView of the iDiv Ecotron with 24 EcoUnits

An Ecotron consists of three units. The lower unit contains the soil, which can either be inserted directly into the container or in extra stainless steel cylinders (lysimeters).
The latter allows the investigation of undisturbed soil monoliths. Up to four lysimeters
can be installed in one EcoUnit. Several soil sensors can be installed in the lower unit to collect soil temperature, soil moisture and soil tension data. To investigate root systems and root growth rhizotrons can be installed as well. The lower unit is equipped with a system to collect seepage water and a system to control the temperature conditions at the lower boundary of the soil. On top of the lower unit a second unit is attached, which isolates the environment above the soil surface from the surrounding. The size of the isolated habitat is big enough for growing of medium shrubs. The second unit can be equipped with additional walls to divide the EcoUnit in four self contained sub units.
On top of the second unit the upper unit is located, which contains equipment for irrigation, lighting and ventilation. The upper unit can also be equipped with sensors to
collect data of temperature and humidity as well as with a gas analyzer. The lower and upper units are equipped with a control cabinet containing the required power supply
and signal transformation as well as the measurement and control technology. The EcoUnit comes with a touch panel to visualize collected data and to control the EcoUnit.
The equipment and design of the EcoUnit are always optimized for
the customer-specific research goal.


UGT was exhibitor at the exhibition WASSER BERLIN INTERNATIONAL 2017 which took place at Messe Berlin from the 28th to 31st of March. UGT was one of 450 exhibitors coming from 26 countries to present their range of products in the field of water. Four challenging days for UGT and agents and partners who visited the booth like In-Situ Europe or eom Austria. We used the opportunity to exchange opinion and discuss innovations and new strategies concerning the cooperation

We thank our dear clients for having seen us in hall 3.2 booth 118. New joint projects were discussed and first ideas were exchanged. In the focus of our presentation at the booth was this year  our technology of flumes with ultrasonic measuring system  which were developed to determine widely fluctuating flow rates, from very low to extremely high volumes. We can not only use them to measure after rainfall events but also these flumes are used to record agricultural and industrial discharge processes. Our cooperation partner Katronic showed at the booth also their ultrasonic system for clamp on ultrasonic flowmeters. Like this we highlighted the different options to use our technology depending on the application. With our high quality of In-Situ sensors and multiparameter sondes we give our clients the opportunity to measure in the  field of water quality and also water level.

Visitors of 20 countries visited the exhibition and nearly all nations also passed by at the UGT booth. Water supply and waste water disposal – this is the blue ribbon that unites the companies that work in this field and our highly estimated visitors from waterworks, water companies, engineers or scientific institutes also used our booth as a forum of brain storming. The conference programme especially attracted our foreign visitors, so from the Iran-conference some of the participants later on informed themselves about the UGT products. The exhibition strengthened the international cooperation. Environmental topics generally were in the focus of our talks. UGT was satisfied with the contacts that we made during the exhibition.

We look forward to see our clients again at the WASSER BERLIN INTERNATIONAL 2019 that takes place from 26th to 29th of March 2019

Inauguration of the new production hall at UGT GmbH Müncheberg, October 28th, 2016

UGT is happy to announce that we have doubled our production size. Our new  production hall has a size of 900m² and so UGT disposes now  of 1800m² production area.


Guests of honour at the inauguration were our  Minister for Economy and Energy of Brandenburg, Mr. Albrecht Gerber, our county commissioner,  Mr. Gernot Schmidt, the president of the chamber of commerce of Ostbrandenburg, Dr. Ulrich Müller, Sebastian Saule, Managing Director ZAB Brandenburg,  leading scientists of the Leibniz centre for agricultural landscape research, the city council of Müncheberg and many friends and business partners of UGT.

The new construction at the UGT premises was supported by the Ministry of Economics and Energy of the Federal State of  Brandenburg. The local authorities such as district and building authorities also supported the project by quick and efficient work concerning the   planning and building permission.

Big projects within Germany and abroad enabled UGT to plan this construction because there the limit of capacity in fabrication was reached  and so we planned a new step to further improve the work flow in our modern production lines.   There will be especially equipped rooms for microelectronics and  microsystem technology.

UGT makes more than 50% of its turnover in export. We cooperate with universities within Europe and abroad and our main share in exports goes to Asia especially to China and South Korea. Lately our first project was realized in Vietnam. Long traditions and narrow customer relations we have to our customers within Europe. Also the Russian market is important for UGT and above sale there are also many scientific joint projects.

The inauguration was combined with a special forum of the 3 chambers of Industry and Commerce of the Federal State of Brandenburg which are located in Frankfurt (Oder), Cottbus and  Potsdam The members of the commitees of external economic relations took the opportunity of a brain storming and exchange of opinion with our Minister of economics and energy, Albrecht Gerber.

The CEO of UGT, Dr. Manfred Seyfarth, the Managing Directors, Mr. Bernd Fürst and Dr. Sascha Reth, cut the symbolic ribbon together with Albrecht Gerber and Dr. Ulrich Müller.


The team of UGT welcomes the new better working conditions and is eager to start production in the new facility.

We thank again all our guests and friends for having spent with us some great time and we look forward to new interesting work projects world wide and feel comfortable to help protecting our environment with our monitoring equipment – made in Müncheberg, Brandenburg.



24 Ecotrons with 96 lysimeters for the German Centre for Integrative Biodiversity Research (iDiv)-key over

October, 19th the official key over for all 24 Ecotrons were be held at the UFZ research field in Bad Lauchstädt, Germany.


The ‘iDiv Ecotron’ is an experimental platform that will be launched in autumn 2016 with a total of 24 experimental units (EcoUnits) operated in a temperature-controlled hall in the UFZ research station in Bad Lauchstädt.


“It allows for the manipulation of horizontal (i.e. within one trophic level) and vertical biodiversity (i.e. the number of trophic levels) to more comprehensively explore biodiversity effects on ecological processes taking aboveground-belowground interactions into account. Diversity of plants, herbivores, predators, soil fauna, and microorganisms can be manipulated along with manipulations of environmental factors such as light, temperature, and precipitation. One EcoUnit is an experimental chamber including a bottom compartment containing about 1,200 l of soil (0.8 m depth) and an aboveground compartment, large enough to grow tall herbs and to allow for realistic aboveground multitrophic interactions. A number of sensors will measure and regulate environmental conditions. To be flexible for different experimental approaches, there will be the possibility to separate EcoUnits above- and belowground into smaller compartments. In this way, for instance, intact soil cores (lysimeter) from locations with different plant diversity can be transferred from the field into the chambers and be subjected to further manipulations.”(Dr Manfred Türke, iDiv-Ecotron)

Summer Initiative – Part IV: Hood-Infiltrometer

The hood infiltrometer is used to measure the hydraulic conductivity of soils in virtually saturated areas as field tests. The infiltration is made from a sealed hood placed on the soil and filled with water. The circular soil surface covered by water beneath the hood forms the source area for the infiltration flux. No additional contact layer and no preparation
of the soil surface is necessary on the measurement area. This not only saves working time but also makes it possible to measure the infiltration and conductivity under completely natural conditions in a destruction-free manner.


The pressure beneath the hood is
controlled using a Marriott’s water supply. The effective increase in pressure on the soil surface can be freely selected between zero and a vacuum up to the bubble point of the soil. This pressure level is shown exactly on a U-tube manometer. The hydraulic  conductivity is calculated from the stationary flux rates determined in the test run
according to WOODING (1968). With the IL-2700 the measurement data for the flux rate is
electronically recorded with a pressure sensor combined with a handheld instrument IL-2700.

With the corresponding software they are transferred to the PC and analysed.The hood infiltrometer is also available without electronic data recording as a favourably priced
alternative which is tough enough to withstand adverse measurement conditions.
In order to guarantee an optimum adjustment of the experiment to the prevailing infiltration conditions, two hoods are available with a ratio to infiltration areas of around 1:2.


The tension chamber, which is an available option, creates a tension infiltrometer
together with the Mariott’s water supply which permits infiltration experiments up to a water tension of around 60 hPa irrespective of the bubble point of the soil. For maximum protection and simple handling during transportation and storage, the complete system is packed in an aluminium framed case with carry grip and foam inlays.

Technical data
• Tension area: 0 … bubble point with hood
0 … 60 hPa with tension chamber
• Tension measurement: U-tube manometer
Resolution 0.1 hPa
• Infiltration measurement: Differential pressure sensor
0 – 70 mba
Resolution 1 mm water column
• Conductivity range of the soil: 10-3 m/s bis 10-7 m/s

Summer Initiative – our product of the week – Part I: ku-pF for the determination of the unsaturated hydraulic conductivity of soil

The ku-pF MP10 is a laboratory instrument for the automatic determination of any saturated hydraulic conductivity ku and the pF curve (water tension curve) in accordance with the condensation method on up to 10 soil ring samples simultaneously. The apparatus is designed for the use of the UGT soil sample rings with 250 cm³ inner volume and 41 cm² cross sectional area. These soil sample rings have bore holes arranged exactly at height intervals of 3 cm for the insertion of the tensiometers. However, they may also be used for obtaining samples separately from the ku-pF apparatus. The filled soil sample rings are set onto filter plates, saturated and sealed basally in the carrier basket for the test run. The gradient resulting from the condensation on the free ground surface is recorded by two tensiometers which record the corresponding water content and the flow rate by periodical weighing respectively. Air bubbles are easy to recognize and eliminate through the acrylic head with bleed screw. The arrangement of the samples on the star shaped carrier which rotates at the set test interval permits the examination of 10 samples simultaneously. The sample on the weighing position is lifted from the carrier by lifting the scales so that it is standing free. The weighing data and the tensions here are stored on the internal data logger. Automatic measuring produces continuous measurement series with a minimum of monitoring. The scales are automatically balanced between weighings. Drift effects or any foreign bodies on the scales do not therefore cause any interference. The ku-pF apparatus works independently of a PC due to the integrated data logger and a microcomputer. A connection must be created to the PC only for maintenance, test start and reading out of the data.


ku-pF MP 10

For a non regular use we provide a single place – ku-pF SP – system to enable all benefits of the ku-pF for a smaller budget.

The following table helps you to find the right system for your need.

UGT GmbH hosts committee of Agriculture and Environment of the county “ MOL”

UGT GmbH hosts committee of Agriculture and Environment of the county “ MOL”

Decision makers in policy of all levels are important partners for medium sized companies.

Especially in the own region the local companies and public authorities need to have a good network.

New regulations in environment influence on the one hand scientific projects and so also give impetus to production lines of medium sized companies. The county “Landkreis Märkisch -Oderland” in Germany has a very active committee “Agriculture and Environment”.

UGT hosted the meeting of the committee on Wednesday, 13th of July 2016 and got in an active change of opinion with the member of the county council. The deputies of the county council were impressed about the performance of the medium sized company UGT that exports the environmental measuring sensors and monitoring equipment into more than 25 countries.

Sensors and production units could be seen and Dr. Manfred Seyfarth also explained the building of the new production hall which comes in operation in autumn – another step forward for UGT!

UGT followed the interesting discussion about new safety regulation for biogas installations and the practical experience of plant operators.

Also interested citizens of our city Müncheberg took part in the meeting which was open to the public.

We are happy to be as a company also part of the local general process of social communication.

Lysimeter – a Unique Tool for Monitoring the Interactions among the Components of Environment

Modern lysimeter facilities in connection with meteorological stations allow monitoring and evaluation of mutual basic components of the environment, such as water, air, soil and vegetation. Water is the most important component of the ecosystem and the component which connects all the other components. Therefore, we need to know the basic distribution and water balance in the different components of the environment to be able to interpret some processes in nature. Rainfall, which is the primary source of vital processes in the soil, is formed in the air. The amount of precipitation that gets into the soil and into the groundwater is affected by weather conditions. Primary distribution of
rainwater is divided between infiltration, surface runoff, transpiration and  evapotranspiration. The amount of water infiltrated into the soil and then evaporated by solar activity or activities of plants can be identified primarily by monitoring changes in weight. For this monitoring we use weighable lysimeter. This equipment with the monolith size of surface area 1 m2 and the depth of 1.5 m is able to follow online updates of weight of the 2 ton body with an accuracy of 100 g. When we add to quantification of leakages through the bottom layer, we obtain a comprehensive record of rainfall at the time in the natural environment of the individual components. The obtained data can be further interpreted in terms of the needs of hydrology, agriculture, and environmental studies, and according to the purpose and objectives for which we want to use them.

With the brand UGT and In-Situ we showed a comprehensive product range in the field of water quality and water level-measurement with our In-Situ level loggers and the multi-parameter sensor AT 600. With the UGT flow-measurement systems from the UGT water related products and with our highly sophisticated sensors in the soil application like the new RFID-tensiometer, the full range tensiometer and our soil moisture probe UMP 1 we offered in this environmental exhibition an interesting programme to our visitors.

At the IFAT there were 3097 exhibitors from 59 countries. Around 138000 visitors from more than 170 nations came from May 30 – June 3 to the Munich exhibition centre “Messestadt West and Ost” to inform themselves and get to know the latest innovation in the field of water, sewage, waste and raw materials. UGT used this platform to present the new full range tensiometer and the RFID plus tensiometer which gives scientists the opportunity for long time monitoring – the first tensiometer that can stay for 3 years in the measuring field.

We want to use the resources of our world in a sustainable way – IFAT proved its approach as   a global event and about 45% of all visitors came from foreign countries.

UGT used IFAT as a meeting point to discuss new projects to show the great combination between the UGT developments and the water related products of In-Situ. New alliances were planned to get for our customer process related solutions.

More than 200 visitors from altogether 27 countries came to see our booth. It was great that each delegation that visited the booth of German Water Partnership also came and informed themselves about the UGT range. Outstanding was the visit from the delegation of Iran and Latin America. Munich was again a wonderful host for IFAT and UGT used the opportunity to combine the IFAT exhibition with a specialized agent training in Freising at our UGT branch office right in front of the doors to the city of Munich. Our partners from our French agent SDEC, Adrien and Thierry as well as our agent for Serbia, Slovenia and Croatia, Marin Antic and Katharina made use of the intensive training opportunity.  After the 2 days training course on the 1st of June customers and partners from UGT booth at IFAT came together for a joint meeting in Freising to exchange opinion with customers and UGT partners and friends. Also networking was a big part of our work. Whereas Markus and Kerstin from UGT worked together at the IFAT booth with Ana and Chris from In-Situ, Sascha Reth joined us for important meetings with clients and partners on the 2nd of June. Our team of scientists in Freising, Sascha, Christian, Katja and Florian presented the UGT equipment and worked together in the field with our agents. Katja Kaminski our secretary in Freising did a great job in organizing and helped to make our visitors to feel at home. Our production team in Müncheberg has done a great job to prepare all the equipment for the exhibition and the workshop for Munich/Freising.

New ideas for the cooperation with our partners see our meeting with Eijkelkamp was planned and many clients recognized good synergies between the classic UGT production programme and the product range that we represent. We thank our customers and visitors for the attention, thanks to the IFAT team – and GWP as our stand organizer! We will be back at the next IFAT exhibition which will take place from May 14 to 18, 2018 in Munich.


General Assembly of the EGU 2016

The EGU General Assembly 2016 took  place in Vienna from the 17th to the 22nd of April. This event   was a forum for geoscientists from all over the world. EGU is an outstanding congress as it brings together in one place the different  disciplines of sciences – which refers to the Earth, planetary and space sciences.

EGU 2016 Banner

The EGU  is on the one hand  a forum where scientists have the opportunity to present their work and give contributions – which can be in the sesscions or in the poster shows. So there is a wide range of discussion and presentation of  ideas among and with experts in all fields of geoscience.

In 2016 UGT presented its work at booth 53 in the congress center and also used the outside area for exhibition. The big lysimeter station which normally is only 1.5 m underground – was a highlight for visitors. Very often scientists came for consultance to our booth 53 to learn more about highly advanced lysimeter technology and get to know all options from:

– laboratory lysimeters

– ready to go – RTG lysimetres

– double and fourfold lysimeterstations


After the visit in the UGT double lysimeter station in Vienna – in brainstorming with our exhibition team Dr. Sascha Reth, Dr. Christian Heerdt and Kerstin Thomsen – the scientist from all over the world  defined their research project and informed about interesting new targets for the use of lysimeters.


Vienna – Berlin – Mumbai – London – Sydney – Chicago – Buenos Aires – Zurich – Munich – these are just a few places where our scientific colleagues came from to visit our booth 53– and EGU is more than a customer – client relation – here the scientific exchange of information and discussion goes hand in hand with the demand for new products. – And UGT is prepared – “ We do development for new monitoring instruments on demand” – we are proud when we hear from the scientists that they could get new information based on UGT-measuring instruments. At the EGU there participated scientists and visitors from more than 100 countries – colleagues from about 50 countries passed by and informed themselves about UGT product range.

Another highlight of our programme was our new portable automatic chamber system. There we offered an ideal combination between lysimeter, gas analyser- UGT is the agent of Picarro – the leading producer of equipment to measure  GHGs, trace gases and stable isotopes found in the air , water  and land. The automatic chamber system from UGT provides a very good measuring tool for greenhouse gasses during the day with the transparent chamber and with the dark chamber to imitate night without photosynthesis.

We thank our visitors and colleagues coming from scientific Institutes and universities from Germany, Europe and all over the world for the interest in our products.

We look forward to the emerging products and will contact you to answer all inquiries,

We look forward to the next EGU – we thank the organizers in Vienna – we  thank for the cordial  welcome in the wonderful city Vienna

The EGU is looking forward to cordially welcoming you in Vienna.

UGT strengthens its activities in the Baltic region – we make soil healthy again – with joint efforts!

Germany and Lithuania work very active together in the field of soil science.  There are on the one hand great projects of the European community but also bilateral scientific partnership between universities and governmental institutions and companies. So UGT as a company is one of the many good examples for this mutual cooperation.


The joint project of Aleksandras Stulginskis University, Kaunas, Lithuania and Technical University Munich (Germany) with the topic “INTEGRATED EFFECT OF CLIMATE AND OTHER ENVIRONMENTAL STRESSES ON FOREST ECOSYSTEM” has started recently.


For UGT it was a pleasure to support the installation of the measurement equipment in the National Park Nationalpark Aukštaitija. Dr. Christian Heerdt explained the advantage of the heat ratio and heat field deformation method, as well as dendrometer measurements. The cooperation with the TU Munich was very good. The installation in the beautiful landscape of Lithuania showed again how precious and delicate we should treat our treasures in environment.


We used these days as a chance for a fruitful discussion about further extension of environmental monitoring instrumentation with the head of the institute Prof. Dr. Algirdas Augustaitis (Aleksandras Stulginskis University), Vitas Marozas (Aleksandras Stulginskis University) and Dr. Manuela Baumgarten (TUM).

International workshop at the Alexandras Stulginskis university in Lithuania, Kaunas, April 8, 2016 – brain storming with international colleagues is a very good investment to define the way towards a healthier environment.

The workshop took place on Friday the 8th of April and dealt with the following topics, see the programme for your information:

UGT expands the production place – start of activities 14th of March 2016

The building permission from the local authorities  has arrived – UGT starts on the 14th of March the building works for a new production hall  in Müncheberg in the Federal State of Brandenburg – This is a new step to enable our company to  better fulfill the demands of our customers in quick time and to improve the working conditions of our employees.

Lets take this event to look back a little  in the history of our company : On 1 July 1992 Umwelt-Geräte-Technik GmbH started its business activity as starbust of the traditional Müncheberg soil research institute, today’s Leibniz-Zentrum für Agrarlandschaftsforschung (ZALF) e.V. [Leibniz Centre for Agricultural Landscape Research]. The founders of the company, Dr. Manfred Seyfarth and Bernd Fürst – today Managing Director of UGT together with Dr. Sascha Reth, started its production first in buildings that belonged to the institute ZALF. But already in 1998 UGT bought the own piece of land in the size of 10000 m² from the city of Müncheberg. This nice piece of land offered the opportunity to built up a well equipped company building with production hall and also a spacious territory  with greenery  to do our own in-situ field research and work with our monitoring equipment.   It was in 1999 when the own company building with production hall has been built up and UGT moved into the own place in the street Eberswalder Straße 58, in Müncheberg. Already in this time, there UGT was well known in Germany, as a leading company for the manufacture of monitoring equipment in the environmental sector. An outstanding feature of the UGT business activities was the own research and development department that enabled the company to develop special solutions for the universities and scientists of environmental institutes and for public authorities.

The employees of UGT have worked for many years scientifically in the fields of soil hydrology, geology and biology as well as in the scientific toolbuilding. Solid expertise paired with extensive scientific and operating experience in the laboratory and in the field is the basis for developing and manufacturing environmental measurement technology with high innovative character, quality and performance characteristics.

According to the company profile UGT produces and sells measurement and diagnostic technology for soil, water, atmosphere and plants as well as modules for environmental monitoring and sets up soil hydrological measurement sites on agricultural, forest, moor and water ecosystems as well as monitoring and control stations on landfills, mining recultivation areas and special locations.

The product range of UGT includes:

Lysimeters and Lysimeterstations, extraction technology for large-volume undisturbed soil monoliths as well as for soil columns of different dimensions, soil hydrological and soil physical measurement devices, climate measurement technology, plant physiological measurement devices, erosion measurement appliances, data loggers as well as soil laboratory devices.

The devices can be designed as laboratory or field devices and can be aggregated to complex environmental measurement stations for year-round outdoor monitoring. With the world wide success of the modern lysimeter stations of PE-material it was already.

So UGT disposed of a modern workplaces to develop and manufacture  applied microelectronics and fine mechanics and was able to produce within  a well equipped production location with machine park and production technologies that served the requirements.

The production location was supplemented in 2003 by an outdoor test area with integrated 4-fold lysimeter station, a weather station and a soil hydrological measurement site. These facilities are used to conduct project work and to verify measurement methods and measurement devices.

Because of the high level of innovation of the new solutions the UGT GmbH holds patent rights for 18 new developments so far and is among the market leaders in the fields described above.

The company concept has proved to be sustainable. Already in 2001 UGT started to manufacture big lysimeter stations made of PE-material. So the next step of building was necessary and UGT opened up the next production hall in 2003 in a height that served the needs of production.

Hard work – very good modern technology and production facilities – an experienced and motivated work team and leaders that were passionate and future orientated for the company led to a continuation success within Germany and abroad. Many projects led the UGT team to all continents and in more than 25 countries UGT equipment is used and helps with exact monitoring data to find solutions  for instance within a sustained land management or to recultivate soils or to enable new hydrological solutions.

In the beginning there UGT started with 9 employees now we have 30 employees in Müncheberg and opened up a branch office in Freising near Munich and a service centre in France. But our main office and production – the heart of the company is in the Federal state of Brandenburg in Müncheberg.

So we are proud to announce that – thanks to our customers – thanks to the development of the worldwide markets and of course thanks to our motivated team of employees we will now double our production space – the new hall attached to the building will have another 900 m² and will give room for the mechanical and electronic manufacture and it opens up also warehouse facilities.

Already in summer 2016 we want to move in!  Share with us the first pictures of the new construction

Yours’ UGT-team

UGT – winner 2015 of the Future Prize “New silk road”

The German Future Award 2015 for Medium sized companies was initiated by the Economic Club Russia. With the proclamation of the Eurasian Economic Union on the 01.01.2015 the way was free to a more connected society and a cooperation in economy, culture and all social fields. This leads to connecting activities between China and Europe, the ‘New Silk Road’ is an outstanding project which demonstrates the process of transformation in economy , culture and the whole society between Asia and Europe.


Layout 1UGT is proud to be an active partner in the process to practically realize with economic projects – especially with our worldwide known lysimeter stations – this corridor of industrial clusters – thus being a driving force in the dialogue between innovative people that work together to create trust and cooperation and further develop the well being of human beings by economic growth under sustainable environmental conditions.

Focus of UGT economic activities is the development, fabrication and sales of highly innovative equipment for environmental monitoring. Target of the project “New silk road” is the development of a reliable measuring network. This work is realized in very narrow cooperation with the Helmholtz-centre for environmental research – UFZ GmbH with main seat in Leipzig. Our key work consists in the development, construction and adaption of lysimeter stations.

Lysimeter can collect all parameters of the water and mass balance of the respective catchment online. This brings environmental monitoring into a new quality. The UGT stations can monitor by the respective clima measuring technique the whole circle.

UGT was founded 23years ago and has always been a very good partner of high ranking scientific institutes within Germany and abroad. UGT is also a partner for industry and engineering companies in the environmental field.


Dr. Manfred Seyfarth, founder of the company, Bernd Fürst, Managing Director, Dr. Sascha Reth, Managing Director of UGT represent the Managing Board of UGT – They express:

“It is our team at UGT that realized this success. We dispose of an experienced team of workers in production and service engineers that travel round the world with our stations and sensor technique. There are our scientists who further develop our products and there are our cooperation partners in the universities and research centres who expand our think-tanc.

There is our sales and marketing team who outside and in the interior service do all to satisfy our clients needs. Thanks to our clients which gave us there trust now about more than 20 years we are today in this position“

UGT represents a sustainable sector – to protect our environment is a global task – climatic change involves the whole world – the “New silk road Award” gives courage and further strength to follow this way.

Today UGT celebrates with partners and friends, among them Prof. Dr. Rainer Horn, chair of soil science, Christian Albrechts university Kiel and President of the IUSS, Prof. Dr. Ralph Meissner, Helmholtz centre UFZ, Leipzig

We look forward to our further joint work!



Support and cooperation – France and UGT have a stable relationship

From the 23rd to the 27th of November 2015 UGT visited our French clients.

Our relationship with our partners in France is on the one hand side an inspiring

Exchange within the scientific community.

We visited the representatives of scientific labs of university Lorraine to further discuss joint projects.

Highlights of our commercial relationship highly influenced by our scientific partnership is the cooperation with GISFI in Homécourt.


The project with ANDRA in Bure were UGT installed a lysimeter station shows how economic application of resources and protection of environment can match together


University and middle sized companies develop new solutions – a soil insight based on research of university Lorraine and further development by UGT will be a new product in the range of UGT.

The license contract was signed by both partners.


INRA and UGT – we visited the site in Lusignan and explored together future potential further opportunities of cooperation. We try to give the scientists what refers to equipment best and suitable solutions


Commercial partnership with a highly specialized company can give our French clients better service and continuant attention. It is therefore that we met up with SDEC in Tauxigny to explore and discuss a strong partnership which is the base for a contract agreement.


Even global international partnership can be further developed at the hub of scientific development in France, so we met the rep of our middle sized Chinese business friend Encanwell who opens up an office in Grenoble.


Scientific work and customized production of UGT according to the needs of our clients match well together. We look positive towards our joint work with our French clients in 2016 and look forward to our joint efforts and projects. We thank our clients and scientific partners for the longlasting trust and wish a merry Christmas and a prosperous New Year 2016

International workshop at UGT South, 21.-23. October – Science meets clients

Lysimeters – separating processes in flux measurement

 UGT as a SME enjoys a number of advantages over its different partly larger counterparts.

Innovation, narrow contact to scientific institutions like universities, technical colleges and other highly innovative institutes in the field of environment give UGT an outstanding position in this market. One example was this international workshop. Altogether 45 participants enjoyed highly professional conference contributions. Dr. Sascha Reth, Managing Director of UGT and the whole UGT team were happy to host this event in Freising. One of the highlights was the research report from Prof. Dipl.-Ing. Dr. Peter Cepuder, BOKU Vienna, Austria and head of the European Lysimeter Research Group. He introduced for discussion among other important topics e.g. the influence of strong wind events on the weighing process and the evaluation of the measurements of the lysimeters.


An open minded atmosphere and a lively scientific and also practical discussion among all participants was a significant sign of this event. Input was given by very good presentations on lysimeter research projects in Slovakia by Ivan Matusek from Kreaprojekt and Mgr. Katarina Hrckova, PPRC Piestany as well as the very good contribution of Dr. Jozsef Zsembeli from the university Debrecen in Hungary who also introduced their lysimeter research projects to the participants.

Frederic Rees, representing the research projects from GISFI France informed about results of the lysimeter research in the field of remediation.

Practical demonstration of equipment by UGT and information on further product improvement gave also new input to the “think tank” of the various scientists and participants in the workshop. A new prestep – how to find soil anomalies in a defined territory – was introduced. This GPR system enables scientists and also the equipment maker UGT to find out exactly about the planned excavation place of the lysimeter.


Dr. Sascha Reth gave an overview about the opportunities and the wide range of utilization of the lysimeters by different case studies. He was highlighting also the special modern and innovative characteristics of the UGT lysimeter technology protected by various patents.

20151021_130006 20151021_13011220151021_133552

Data Service and visualization is a key point for all users to evaluate the data gained by the sensors in the lysimeter. Dirk Römermann, Lysidata & SVADDS informed about the opportunities to work most effective with these systems.


The second day continued with highly interesting research reports on simulation of water balance components at shallow groundwater sites by Dr. Ottfried Dietrich Zalf, or the report of Dr. Steffi Knoblauch, TLL Jena, on nitrogen leaching and fluxes in lysimeters. Dr. Manfred Türke from iDIV Leipzig gave highly interesting input about the work with Ecotrons – a very much future orientated field of activity; Oscar Perez-Priego, scientist from MPI Jena, gave a great report on the currently running research project dealing with evaporative flux partitioning using lysimeters and sap-flow and eddy covariance. Martina Zacios, from LWF Freising informed, gave in her contribution very good experience about the heat ratio method for sap flow measurements.


A great Forest research plot –  “KRoof-project-Kranzberg” was introduced to the members of the workshop by Dr. Karl-Heinz Häberle from TUM Freising. Dr. Christian Heerdt from UGT concentrated in his contribution on findings concerning sap flow and water potentials of plants. There was a very intensive discussion also concerning these applications.


Who works intensive and with fun deserves also to party with fun – all participants enjoyed the Bavarian Evening in the traditional Beer garden “Wirtshaus Weißbräu Huber”.

International agents of UGT like MEMECO USA, represented by Don and Gregory Jenkinson, Kreaproject Slovakia, represented by Ivan Matusek or MEGRA, Serbia, represented by Marin Antic used the opportunity to intensively discuss with science on the one hand side and the UGT team concerning the practical realization of projects. We have built a bridge between scientific and technological expertise. We gave advice and contribute herewith to form an appropriate network.


The last day of the workshop was mainly dedicated to introduce scientific research projects in the field of gas and water analyzers. UGT represents PICARRO USA in this innovative field. Dr. Renato Winkler from PICARRO Europe introduced the equipment and gave practical demonstration.


Martina Schlaipfer, HSWT Freising, gave information on her research project concerning trace gas emissions form managed peat land. Dr. Paul Königer, BGR Hannover, reported on his innovative study concerning stable isotopes in soil water.

Science meets business – we are proud about this interactive communication.

This workshop was also a platform for UGT to conclude 2 new Gentlemen Agreements with new partners. We are happy and proud to announce among our agents now:

MEMECO, represented by Mr. Don Jenkinson, covering the territory of USA and

MEGRA, represented by Mr. Marin Antic, covering Serbia, Slowenia, Bosnia and Herzegowina, Croatia, Montenegro

UGT Freising offers for a workshop not only very good working conditions but also after work a wonderful surrounding. We were happy to have on Saturday before departure to the US to Don and Greg one of our most beautiful castles near Munich, “Neuschwanstein”


We thank again all our participants and lecturers. The contributions will be made available on a drop box. We are looking forward to our next upcoming workshop.

UGT at AOGS in Singapore

From the 2nd of August to the 7th of August Singapore hosts the 12th annual meeting of AOGS.

Asia Oceania Geosciences Society (AOGS) was established in 2003 to promote geosciences and its application for the benefit of humanity. More than 1800 participants and research fellows from all over the world have arrived to exchange opinion in the field of soil and hydrology under the aspect of geoscience.


Dr. Sascha Reth holds an oral presentation with the title:

Influence of a tension controlled lower boundary in lysimetres (HS02-D5-PM1-312-013)


It was a plesure to have this talk with a lot of interested listeners. Questions like:

  • how to measure exactly the evapotranspiration, or
  • what is the influence of the temperature control, or
  • to manage the lysimeter together with other measurement instruments, like gas analyzers and sap flow?

encourated us to further develope and investigate these topics.


At booth E04 Sascha Reth and Kerstin Thomsen show the equipment of UGT and give evidence of the wide ranging product groups of UGT. Already at the first day our booth was a centre of interst for the visitors. Also other Asian partners of UGT like from Vietnam and Malaysia make use of the chance to come and see UGT in Singapore.

We had more than 20 participants at each UGT place and our customers appreciated highly the very practical seminar. A short necessary amount of theory and than everybody started working, digging, taking samples nearly “undisturbed” and disturbed ones.


From the famous “Edelmann” driller to the split tube sampler. Heavy technique like the “percussion coring tube” demanded muscle power in the team. Beside of the knowledge and exchange of experience joy and fun facilitated the joint work.

This course was combined with information concerning the UGT technology and there was interesting ways that showed how to combine UGT-technology with Ejkelkamp-technology.


A good match, Katja Weber, scientist in the field of hydrology accompanied the participants and even new product ideas emerged out of the exchange of experience.

Kerstin Thomsen, strategic sales Manager from UGT had the chance to talk to the customers about new projects.

Last but not least the UGT teams in Freising and Müncheberg were very good hosts and provided for our customers a nice meal from the field kitchen. Our internal customer service in Müncheberg and Freising, Jeannine, Nancy, Jenny and Stefanie took very good care for the wellbeing of our customers – thanks to the Team!

Thanks to the participants – please join us soon again! Thanks to our lecturers – we are looking forward to have you soon here again!

Service is our top target and we will keep up with the development in all fields and we invite you dear customers to join us – learn more about the equipment – and to have a good time with us.

Yours’ UGT-team in Freising and Müncheberg

Project MANIP / Spain: First Results of the Comparison between Lysimeter, Eddy Covariance and Sapflow data

Here we present some preliminary results of water fluxes acquired with weighing lysimeters and sap flow sensors in a tree-grass ecosystem in Majadas (Spain).


Tree-grass” ecosystems. Mixed tree-grass systems are widely distributed (~16-35% of global land-surface) vegetation formations such as tropical and Mediterranean savannas, the “waldsteppe” in Eurasia and culturally influenced vegetation types such as agro-forestry systems or grazed open-forests in Europe (Hanan & Hill 2011). Semi-arid tree-grass systems are considered one of the major contributors to the interannual variability of the global carbon cycle (Poulter et al., 2014).Despite their wide distribution, Earth observation systems, and associated land-surface modeling development have been so far poorly adapted to the key structural and functional characteristics of tree-grass ecosystems. As consequence a significant uncertainty and bias in the assessments of energy, carbon, water and biogeochemical dynamics is often observed (Hanan & Hill 2011; Beringer et al. 2011). Nutrient (N, P) imbalance. Human induced CO2 and N fertilization leads to a stoichiometric imbalance, which confers an important role to P availability and leads to shifts in C-N-P ratios and balances (Peñuelas et al. 2012). N/P imbalances are particularly important in water-limited ecosystems (Sardans et al., 2012), where the synergistic effect of water and nutrient (N and P) availability/imbalance could impact ecosystem functioning, structure, allocation patterns and the nutrient and carbon cycling, and ultimately how the ecosystem will respond to extreme drought events. Hence it is important to study the effects of N and P imbalances under different water regimes, in particular in mixed tree-grass at ecosystem scale. MaNiP project offers an original experimental design integrating cutting-edge approaches (including eddy covariance, lysimiters and hyperspectral; remote sensing) to study the combined effect of nutrient and water limiting factors on fundamental ecosystem, plant and soil processes.

Soil variables (soil tension and volumetric soil water content; SWC) at different soil depths (line 10 cm and dashed line for 40 cm), and climatic variables ( daily Precipitation) are presented to describe the seasonal time course of daily evapotranspiration (ET) measured with the lysimeter. Data allow us to get more insight into non-well known processes that drive water flow upward and downward and determining water budgets in soils.

In the following plot, we show the agreement between the diurnal time course of ET aquired with two lisimeters and an eddy covariance tower. Sap velocity are also overlapped to investigate the contribution of the tree and grass transpiration on the ecosystem ET.


Thanks to the group of the Max Planck Institute for Biogeochemistry, Department Biogeochemical Integration for the first results in this study. The figures above show clearly that the methods match perfectly together!

UGT – „open house“ on 3rd of May in the margin of the local event „Kaiserbergfest“ in Müncheberg –

Our products being shown at the EGU – European Geosciences Union General assembly 2015 in  Vienna – now in Müncheberg – highly innovative products in the focus of our inhabitants of Müncheberg!

The first weekend in May, Müncheberg celebrated the 5th public fair “Kaiserbergfest” which attracted people with games, fun and entertainment.

As a local company of Müncheberg UGT used the opportunity to show our company and our products to the people of Müncheberg.

About 100 inhabitants of Müncheberg made use of this opportunity and got a very warm welcome in our Company.

Vortrag zur Geschichte der UGT gmbH

Presentation about the history of UGT GmbH

We showed our products in the field of environmental monitoring from the lysimeter to the weather station. Our hosts – the Managing Director, sales department, scientists and our experienced work team were happy to answer the questions of our guests concerning the various products as well as development and future challenges of the company.

Chinese Delegation in Freising at UGT GmbH

April, 23rd a Chinese delegation visited the Branch South of UGT in Freising. Beside the broad range of soil physical instruments, the lysimeter solution of UGT aroused great interest. The lysimeter as a tool for environmental observation –including soil, water, plants and the atmospheric boundary layer- is the solution for the future. 20150423_104057_resized

Lysimeters on tour – part 2

Together with the Lysimeter Conference in Gumpenstein 2015, a meeting of the international steering committee of the Lysimeter Research Group took place. Dr. Sascha Reth (managing director of UGT) – as a member of the steering committee – was delighted by the work in the last year. A highlight was the lysimeter excursion in the fall 2014. See the report under following link:


The positive feedback on the UGT installations of lysimeters in Borovce, Tatranská Javorina and Michalovce, all in Slovak Republic was given in the group.


At the conference itself we have present our PE-HD lysimeter station in front of the conference building. The participants got the chance to visit the station and discuss the need for their projects.

Lysimeters on tour – visit us at the EGU 2015 in Vienna

Take the great opportunity to visit UGT at the EGU. We are happy to show you the latest developments at our booth No.53. Here you will see the new Full Range Tensiometer at work.

EGU 2015 Banner

Measurement of the soil water matric potential (ψm) is important to characterize and monitor processes in vadose zone hydrology, such as plant growth, crop production, aquifer recharge and leaching below buried waste disposal sites. Tensiometers are widely used instruments for monitoring and have been used for almost 100 years already. Unfortunately, water-filled tensiometers are only able to measure (ψm ) up to approximately – 90kPa. Soil physical experimental research is hampered by this very limited measurement range. The Full Range Tensiometer is comparable to water-filled tensiometers, but measures over a larger range. Hereby the Full Range Tensiometer measures the soil water potential directly.



  • fast response to changes
  • higher measurement range than usual tensiometers
  • self refilling
  • direct pressure measurement

Available in 3 measurement ranges:

  • Full Range 5: pF 3.7 ( +50 to -500 kPa)
  • Full Range 15: pF 4.2 (+100 to -1500 kPa)
  • Full Range 25: pF 4.4 (+100 to -2500 kPa)

Outside the conference hall we have build up a real working lysimeter station. We are happy to explain you the world leading technique of the UGT lysimeters. Another good opportunity is to learn about the full range of lysimeter uses as the combination with Picarro analyzers – for water, gases and isotopic analyze– as well as plant related instruments from ICT International. With the instruments you enable the full information of the water flux and water potential in plants.



Further on the lysimeter range will be completed with a data management service of SVADSS to get always the best view on your data.


Strong engagement of UGT in the field of hydrology

The international exhibition Wasser Berlin International was held from March 24-27 in Berlin. This exhibition was an important event for UGT to meet our clients from Germany and abroad.
