RESOURCE-SAVING WAYS TO IMPROVE MOUNTAIN FORAGE LANDS

New resource-saving aggregates designed for the restoration of degraded mountain grasslands are presented. The aim of the study is to restore the natural phytocenosis by the method of surface improvement of natural meadows using new mining modification aggregates. The object of the study is the results of using aggregates for cutting hummocks, removing stones from the site and sowing grass seeds. The research objectives included: assessing the impact of cultural and agricultural measures on the change in the floral composition of the herbage, identifying the effectiveness of the developed aggregates for mountainous areas. The novelty of the technical solution is the development of new resource-saving ways to improve mountain forage lands using small-sized universal units. The tests were carried out at a mining hospital located on the southeastern exposure of the Dargava basin of the Republic of North Ossetia - Alania at an altitude of 1,650 m above sea level with a slope of 130. It was found that changes in the quality and quantity of herbage had an impact on the yield of above-ground fodder mass, which, when seeding grasses, amounted to 21.8 c/ha of dry weight in the first year of observation, which is 3 times higher than in the control. During the growing season of the third year of observations, the harvest in the sown area amounted to 39.2 c/ha of dry weight versus 19.3 c/ha in the control.
