It was studied the effect of No-till technology on soil density, soil
moisture reserves, soil microbiological activity, and crop yields. It was found that the
soil density under winter wheat according to No-till technology did not exceed the
optimal index of 1.30 g/cm3 and it was 1.14-1.25 g/cm3 for the sowing period and it
was 1.18-1.29 g/cm3 for the harvesting period. The moisture content in the soil was
significantly higher according to No-till technology and it was amounted to up to 21.3-
27.6 mm during the winter wheat sowing period and it was 22.4-27.4 mm during the
harvest period, where as with traditional technology this indicator was 16.8-20.2 mm
and 17.3-23.9 mm, respectively. The average yield of winter wheat using No-till
technology for two years was 4.54 t / ha, yield of soybean was 2.24 t / ha, yield of
sunflower was 2.71 t / ha. The increase in crop yield up to 14.3-22.9 % by No-till
technology allowed us to draw a conclusion about optimizing soil fertility indicators
in the climatic conditions of the southern Steppe zone of Ukraine in comparison with
traditional intensive technologies.
It was shown that the introduction of No-till technology would improve
environmental processes in the soil, reduce the anthropogenic load on agroecosystems
and the manifestation of erosion processes, increase crop yields and reduce energy
costs for their cultivation.
