Effect of perennial grasses on nutrient supplies of Southern black soil and subsequent crop yield

oai:ojs.european-science.com:article/4The present paper gives the comprehensive analysis of the effect of traditional and nontraditional grasses on soil nutrition status and subsequent crop yield. Substantial contribution of perennial grasses to soil organic matter accumulating is assessed. It has been observed that humus content and nutrition components changed throughout grass cultivation. Phytomelioration impact of five leguminous species and three nonleguminous on Southern black soil fecundity is overviewed. Among spring wheat yield components, the significance of influence of different grasses is underlined. The study evaluates the benefits of legume grasses in comparison to nonlegumes
