Abstract:
It is found that a more environmentally efficient nitrogen balance on sod-podzolic soil of a slope develops after incorporation of clover biomass. Oat plants utilize 37% of clover N on the crest-close slope and 25% in its lower part; in this case, 55 and 50% N, respectively, become soil-stabilized; 8 and 25% N are lost. Minimum nitrogen quantity is used up by oats from organic sources after incorporating timothy biomass; the maximum of 69 and 59% become soil-stabilized, its highest losses reaching 14–27%.
