Influence of pasture grass stands on indicators of soil fertility of drained soils of the Central part of the Non-Chernozem Zone
The article presents the results of studying the development of the root mass of multi-species pasture grass stands on the basis of the ryegrass of a pasture and intergeneric hybrid - festulolium and its effect on the fertility of drained soils. Species and varieties of herbs were selected taking into account their potential productivity and sustainable longevity in conditions of growing on drained soils: ryegrass pasture (Loliurn perenne) VIC 66, festulolium (x Festulolium F. Aschers, et Graebn) VIC 90, alfalfa changeable (Medicago varia) Nakhodka, lagoon horned (Lotus cornilatus) Solnyshko, clover creeping (Trifolium repens) VIC 70, red fescue (Festuca rubra) Sigma, clover meadow (Trifolium pratense) VIC 7, timothy grass (Phleum pratens) VIC 9, fescue fescue (Festuca pratensis) Sakharovskaya. It is shown that the cultivation of pasture grass stands with the participation of ryegrass pasture and festulolium has a positive effect on the agrophysical and agrochemical properties of the drained soils: soil density is optimized, nutrient accumulation is occurring, and humus content in soil is increased by 0.07%.
