Popis:	The result of 50-years scientific researches, conducted in 10-fields crop rotation on the grey forest dusty light-loamy soil in the northern part of Forest-Steppe at the experimental farm DPDH “Chabany” of National Scientific Centre “Institute of Agriculture of UAAS” are presented in this work. There is stated the importance of potentional soil Fertility forming with saving or increasing of absorbed cation sum, which determines its amelioration processes and provides optimal terms for organic matter and nitrogen compounds transformation. A direct correlation is found between fertilization and labile phosphorus and exchangeable potassium accumulation. The moderate organic-mineral and renewal fertilizing systems are economically and ecologically sensible.
