Pessl Instruments is one of the nine EUXDAT consortium members. We provide an agriculture eco system with agriculture sensor monitoring in the area of weather sensing (rainfall, temperature, relative humidity, soil temperature, soil moisture etc.), disease predicting models, insect migration monitoring tools, soil nutrition and water management – http://metos.at/home/. Our devices are used mainly for applications in agriculture (irrigation/plant protection), viticulture and horticulture.

Within the EUXDAT project, we act as one of agriculture experts, providing ideas on potential precision farming recommendations based on integration of satellite data and data from our own ground IoT hardware provided via adequate APIs. In particular, we work on a development of biomass (Figure 1) and zoning maps for seeding, spraying and fertilizer applications based on a) Sentinel-2 data, b) data from the METOS soil moisture sensors as well as c) data from smartphone cameras.

During these days, experiments are being conducted on 6 different fields in Styria, Austria, to develop an improved biomass estimate from Sentinel-2 for wheat, corn, oats and rye using smartphone camera-based application (FieldGreen). The results demonstrate a high correlation between Sentinel-2 and FieldGreen and thus the future ability to integrate farmer’s camera acquisition with the satellite acquisition. Such integration was shown especially relevant during May/June 2017 and 2018 in Styria when early season heavy rains and cloud coverage hampered the Sentinel-2 data availability.
