Rezumat

In the soybean cenosis (mainly the Aura variety) with a characteristic density (400-500 × 103 plants/ha), the dynamics of soil moisture in the years preceding the drought-2020 was studied. The main factor of drought-2020 is the low (about 100 mm lower than the average annual value) moisture accumulation in the soil before sowing for the autumn-spring 2019/2020, mainly due to low precipitation. An additional prerequisite for drought-2020 is a decrease in soil moisture (including deep soil layers) during harvesting in recent years, which is the reason for an additional deficit in a soil layer 0-100 cm of approximately 25 mm of water.
