Tarika O. Agroecological basing of the loess-like loam usage and developing during mine-land reclamation in the Nikopol manganese ore basin

The work presents agroecological basing of the technology to be used for creation of the high-productivity forage areas on the bladed surface of loess-like loams without topsoiling with zonal soil strata in the conditions of Southern Steppe of Ukraine. Research shows: a) significant changes of the physical, hydro-physical and agrochemical properties of the edaphotops made from loess-like loams during agricultural usage; b) effectiveness of joint grows of legumes and grasses on loess-like loams; c) optimal composition of the agrophytocoenosys components was founded ерфе provides obtaining of the highest hay and forage units yield, nitrogenated compounds on loess-like loams during any years and all period of vegetation. It is recommended for the agriculture usage to create perennial legume-grass mixtures on loess-like loams by planting mixture components at rate (mln germinating seed per hectare): 3 legumes species by ~2,0, 2 grass species by ~0,5. Nitrogen fertilizers application must be used starting from 5th year of grows on the rate N45.
