Currently, the ground within-field agrophysical information and remote sensing data fusion is the most promising approach of real-time soil moisture measurement with high spatial and temporal resolution for substantiation and subsequent site-specific application of nitrogen fertilizer in the precision agriculture. The paper presents an integrated system for collecting ground-based agrophysical information and weather conditions with the use of wireless sensor network. The system includes 7-channel agrometeorological station located next to the experimental fields with the Internet channel for remote access to the measured data, a soil vertical profile moisture sensor and a needle-type moisture sensor for topsoil route survey measurements. The agrometeorological station used for measuring temperature and relative air humidity, soil temperature, wind speed, accumulated precipitation, photosynthetic active radiation and radiation balance. The preliminary results of testing the prototype of in-field integrated system on the soddy-podzolic soil of the Menkovo experimental station of Agrophysical Research Institute (biopolygon of ARI) in 2018 are reported. The complex spatial attribute information was transmitted into the database of the GIS-ARI and was used for remote sensing data interpretation in the experiments on the precision crop production.
Keywords: precision agriculture, remote sensing data, dielectric conductivity, volumetric moisture content, soil moisture profile, soddy-podzolic soil
