Yatsenko S. Effect of soil-protecting technologies on the erodible resistance and fertility of typical severe washed-off chernozem

Subject of research - the processes of erodible resistance formation and changes of typical severe washed-off chernozem fertility indexes. The purpose of research - to establish the effect of the long-term use of crop growing technologies on the erodible resistance and soil fertility. The research methods are field, measuring and weight, laboratory and field, laboratory, computational and comparative, statistical and mathematical. The mechanism of erodible resistance formation is revealed and ways of the typical severe washed-off chernozem fertility index optimization are established when long-term thirty-year conducting soil-protecting technologies of crop growing. The crop growing technologies on eroded soils are improved what promotes the decrease of the erosional process intensivity and increases the crop yield. The results of investigations are introduced in the Obukhiv district of the Kyiv region in 2006-2007 over a total area 763 ha. The branch of application - the agricultural production.
