INFLUENCE OF STRUCTURE OF CESPITOSE GLEYED SOILS ON EFFICIENCY OF THE MIXED CROPS OF PERENNIAL GRASSES
As a result of researches spatial heterogeneity of the soil on the skilled site of FPBSI Kaliningrad SARI with the mixed crops of cereal herbs and Galega orientalis Lam. is established, what exerts impact on efficiency of green material and seeds. Structure of the arable horizon - is poorly compacted, is lumpy, with a tendency to increase the quantity of large blocks with an increase in the degree of hydromorphism of soils. Reaction of the environment in arable soils is close to neutral, the maintenance of a humus in the arable horizon of the studied soils conforms to agroecological requirements of a Galega orientalis Lam. Soils are carbonate, the maximum of carbonates is dated for the lower illuvial gleyed horizons. The mode of humidity of the soil has shown that the mixed crops of a Galega orientalis Lam with cereal herbs are highly productive in various areas of soddy gley soil. The sod gleyed soils (subtypes of cespitose and gley) have high potential fertility for cultivation of bean cultures and a Galega orientalis Lam. with cereal herbs in particular.
