Abstract
The research was conducted on the Bila Tserkva National Agrarian University experimental field on a typical deep, low-humus chernozem.The methods of main cultivation in the sunflower agrocenosis of grain-row crop rotation had a major influence on the soil structuring processes.The use of moldboard and no-moldboard tillage increased the number of the most agronomically beneficial aggregates (0.25-10 mm) in the 0-10 cm soil's layer at the beginning of the sunflower growing season by 6.0% compared to shallow no-moldboardof tillage the soil.By the end of the growing season in the sunflower agrocenosis in the 0-30 cm soil layer, compared to the beginning of the crop growing season, the number of agronomically beneficial aggregates (0.25-10 mm) decreased, the number of fractions larger than 10 mm and fractions smaller than 0.25 mm increased.The coefficient of structure for moldboard and no-moldboard tillage significantly increased compared to shallow no-moldboardof tillage.The use of shallow no-moldboardof tillage and moldboard with no-moldboardof tillage was led to an increase in the content of stable aggregates by 1.2-7.5%.The highest yield of sunflower was recorded for the use of moldboard with no-moldboardof tillage -2.72 t/ha, which is significantly higher than other variants.The use of shallow no-moldboardof tillage for 10-12 cm with disc tools led to a notable decrease in productivity compared to the control.Improving the water resistance of soil aggregates during moldboard and no-moldboard tillage and shallow no-moldboardof tillage helps to preserve the soil's potential fertility.
