UGT & ICT International have been working closely together for many years to
bring best monitoring technologies to scientists and managers of agriculture and
the natural environment. This to enable a better understanding of water and
water fluxes in the soil-plant-atmosphere continuum. These topics grows in importance
as the with population pressure and climate change understanding and
management of water becomes ever more critical.
Lysimeters are a proven tool for ecosystem studies. They are the reference system
for matter and energy fluxes in rather undisturbed systems. Big enough to provide
a root space for representative plant stands, they measure precise and detailed
enough to describe fluxes at high resolution. Pesticide leaching, and greenhouse
gas emissions can be quantified for the well defined lysimeter volume.
IoT Monitoring Solutions for the soil-plant-atmosphere continuum.
ICT International manufactures instrumentation which is key to measuring the
soil-plant-atmosphere continuum, enabling in-situ real time measurement of sap
flow (SFM1) and plant water potential (PSY1) in absolute terms. ICT International
products are specifically designed to be deployed in rugged field environments,
use low-power, have wireless and internet connection. These instruments have
been installed around the world – from the Amazon rainforests to the Canadian
In 2019 ICT International released a suite of integrated IoT enabled sensing solutions
designed specifically to measure the soil-plant-atmosphere continuum. IoT
monitoring systems offer new opportunities for monitoring and management in
many diverse applications such as ecophysiology research, commercial orchard
production and lysimeters.
This workshop will provide an overview of these new technologies and training
in their use. Also future monitoring and management opportunities from IoT
