Abstract: The results of research on the influence of basic tillage methods on agrophysical indicators in soybean cultivation are presented. Over the years of research (2017-2019), the soil density (0-30 cm) during soybean cultivation according to the studied methods of basic tillage was optimal for plant growth and development and was within the range of 1.00-1.27 g/cm3 before sowing; 1.05-1.19 g/cm3 during the branching phase; 1.10-1.36 g/cm3 before harvesting. The reserves of available moisture before sowing in the twenty-centimeter layer of soil were characterized by satisfactory and good security (30.4-43.0 mm), the meter layer-good and very good security (150.8-172.3 mm) on variants with soil treatment and satisfactory at zero treatment-125.1 mm. In the phase of soybean branching, the available moisture reserves at a depth of 0-20 cm were characterized by satisfactory water availability (31.0-35.6 mm) and good (159.6-160.6 mm) in the meter layer of soil. Before cleaning, the available moisture reserves were characterized by satisfactory security. The highest yield was obtained by a differentiated method of tillage (20-22 cm) with an excess of control (dump method, 20-22 cm) by 0.06 t/ha. A decrease in the depth of processing (12-14cm) led to a decrease in the yield of soybean grain by 0.07-0.11 t/ha for the studied methods of basic soil treatment.
