ECOLOGICAL VALUE OF PASTURE SOILS OF NORTH-CAST PART OF MINOR CAUCASUS IN BOUND DASHKASAN REGION
The mountainous greenlands of the republic give a quarter of all forage. However an absence of the regu- lar care and unsystematic use result in their degrada- tion. There fore conduction of the ecological values and elaboration of the scientific grounded conseptions and technologies on improvement and rational use of the summer haymacings and pastures are highly actu- al problem. We have conducted an ecological value of the pasture tands with the calculation of soil-landscape conditions over three ecological zones: mountain- meadow, mountain-forestry; mountain-steppe.The main, unfolded and total bonitet scales are com- posed, an agroindustrial grouping are carried aut. Un- der conduction of the soil ecological value where are accounted both soil pecularities and ecological (local- ity height, erodity, stepnesses, precipitatons, exiosition, microelements content, productivity of fitosenoses, hY, soil bonitet mark and etc) soils of the mountain-meadowfertility (without fertilizers and N). Seeds treatment withzone got 70 marks, mountain-forestry soils-74 marksMicromack without fertilizers has increased the yield per1.14-3.18 c/ha. Micromack usage in combination with has increased the yield per 3.5-3.7 c/ha. They haveand mountain steppe-67 marks.
