The paper provides the approaches to the design and development of information-measuring systems for the reference data formation in order to improve the accuracy of the agrophysical soil properties determination from satellite data. The information-measuring systems (IMS), including wireless sensor networks (WSN), facilitate the monitoring of soil conditions with high precision and can efficiently detect adverse status. To determine the main properties of soil cover based on remote sensing data at global scale, in situ ground truth measurements based on IMS are required which allow to calibrate and validate the obtained satellite information. Complex monitoring of the spatial variability of soil agrophysical properties and the meteorological information influencing the management of crop production technologies has being implemented at the AFI experimental station (Leningrad region). The possibilities of the scientific and technical infrastructure of IMS for determining the main soil characteristics and detailing their spatial and temporal distribution can be expanded through on-the-go soil sensing and a wireless underground sensor network (WUSN) for improving the interpretation level and scalability of the agrophysical properties’ assessment based on satellite data. The structure of WUSN for soil moisture and temperature profiles monitoring with high temporal resolution and the structural scheme of the underground sensor node that communicate untethered through soil are considered. Preliminary results of field tests of mobile complex for determination of agrophysical characteristics of arable soil layer in real time are given. The obtained maps of the spatial distribution of soil moisture and electrical conductivity will determine the nature of the spatial heterogeneity of yield and used to determine the strategy of the spatial location of stationary sensor nodes of WUSN, that function during the vegetation period.
