Abstract

The unregulated use of mountain fodder lands has led to the degradation of soil and vegetation. The use of the biologically active drug "Extrasol", zeolite-containing agro-ore and humus of sheep manure on the natural forage land of the mountain zone contributed to a change in the composition of soil nutrients by reducing the acidity of the soil solution. The germination of fallow seeds of cereals increased from 30.4 to 55.3%, legumes from 5.2 to 17.1-26.8%, which had an impact on the reduction of weed forbs from 64 to 27.6-19.5 %. The change in the structure of the herbage contributed to an increase in yield from 9.9 to 69.4 c/ha of dry weight, the concentration of feed units from 0.9 to 6.1 thousand feed units and MA to 73.9 GJ/ha, allowing to increase the load livestock on pasture and its productivity, while maintaining the ecological stability of mountain agricultural landscapes.
