Impact of surface improvement measures on low-yielding summer pastures on pasture productivity and forage quality

Cultivation of soil on the slopes of mountainous areas leads to a decrease in organic matter and nutrients in the soil and severe soil erosion. Grazing is one of the main reasons for the degradation of pastures and natural landscape, which increases the sensitivity of the soil to erosion. Soil erosion, in turn, pollutes water by increasing its turbidity and sometimes causes atrophy due to leakage of phosphorus and nitrogen. An average of 30.6 quintals of green mass or 7.8 quintals of dry grass per hectare was produced in the variant of grass seed sowing (without fertilizer), compared to the control variant, in the variant of grass seed sowing + N60P60K40 this indicator averaged 39.9 centners/ha of green mass. or more than 15.0%, resulting in the production of 10.0 quintals of dry or 14.7% more dry grass. Experimental field studies to improve pastures have shown that the fodder produced in each of the tested variants; green mass and dry grass supply and their nutritional value were higher than control.
