Abstract

 The spatial heterogeneity of soil productivity in the plain areas of the Right Bank Forest-steppe of Ukraine is considered in connection with the peculiarities of their water regime, first of all, with the duration of spring flooding of micro-depressions (or potholes)  with melt water. The decrease of soil yields on the bottoms and slopes of micro-depressions was revealed. The highest yield of winter wheat was observed on light-loam typical chernozem (black soil) -51.2 c / ha, distributed on plain parts of the field. On the slopes of micro-depressions yields decreased and at the bottom of the depressions (potholes) it was only 16.5 centners per hectare. Total harvest losses from fields amounted to about 22-23%, lack of wheat yield was 38 tonnes on a research field  area of 32.5 hectares. In general, in the farms with 633 hectares of wheat, the shortfall of crops was 740 tons. The use of UAVs (drones), GPS receiver and Landsat-8 and Sentinel-2 space images was substantiated to study the dynamics of typical chernozem productivity, water regime of micro-depressions and vegetation state . The use of these tools for the preparation of detailed soil maps of plains with micro-depressions (potholes) is proposed.

Key words: special heterogeneity, productivity, soil, micro-depressions, water regime
