Abstract

In short-term cotton-crop rotation fields agrophysical features was achieved improvement by sowing pure rape, peas + rape, peas + rape + chick peas are 22–32 tons of biomass per hectare of land is sown in the fall. In particular, when peas + rape, peas + rape + chick peas are used as siderites, macroaggregates in the topsoil increase by 7.87–8.73% and in the subsoil by 3.35–3.50%, when water-resistant aggregates are planted with gooseberry (55.82%) and pea when mixed with rapeseed and peas (56.7%), and increased soil fertility. As a result, the decrease in soil volume had a significant effect on the increase in water permeability and soil moisture more than 2%. The highest moisture content was observed in the mixture of peas + rape + chick peas as a siderite, and when rapeseed was used in its pure form. Sideration has resulted in an increase in organic humus in the soil and an optimal retention of moisture.
