Abstract
Perennial leguminous grasses reduce yields on sod-podzolic slightly washed soils by an average of 14 % compared to non-eroded soils, on medium and heavily washed soils – by 20 and 25 % respectively. Depending on the developing hydrothermal conditions of the growing season, the decrease can reach 30 %. Under the same soil-geomorphological conditions, the alfalfa of the north reduces the yield to a greater extent compared with the eastern galega and meadow clover.
Perennial legume-cereal grasses reduce yields on sod-podzolic medium-washed soils by an average of 11 %, on heavily washed soils – by 19 %. Annual legume-cereal grasses reduce yields on sod-podzolic slightly washed soils by an average of 10 % compared to non-aerated soils, on medium and heavily washed soils – by 18 and 25 % respectively. Annual grasses to a greater extent reduces the yield on sod-podzolic soils on moraine loams compared to soils on loess-like loams.
