Abstract

In order to study the spatial relationships between the distribution of moisture in the 0‑5 cm layer of soil cover and the distribution of local irrigation rates along the pressure front of the sprinkler, a study was carried out, including the measurement of moisture along this front, as well as subsequent data analysis. Moisture measurement was carried out at the soybean sowing site, sprinkling of which was carried out by SM «Kaskad». The analysis of the results included statistical and geostatistical processing of measurement data, as well as analysis of the results of computer modeling of zonal irrigation norms and their comparison with zonal values of humidity. As a result of the analysis, the relationship between the influence of the uneven distribution of local irrigation norms on the formation of spatial patterns of moisture of the surface 0‑5 cm layer of soil cover was revealed. At the same time, it was shown that, despite the revealed correlation between the zonal values of humidity and the zonal values of irrigation norms, there are still a number of factors and conditions that could have a significant impact.
