Economic and power efficiency of application of different systems of fertilizers under winter wheat on typical black soil in Left-bank Forest –steppe of Ukraine

Abstract

Application of fertilizers is one of the most important
directions of productivity increase of crops and
improvement of soil fertility. With the increase of doses
of mineral fertilizers the prime cost of 1 cwt of winter
wheat grain rose, but a net profit and the coefficient of
power efficiency diminished. Exploitation of soil without
application of modern technologies of crop growing and,
in particular, without taking measures on reproduction of
his fertility will result in the catastrophic decline of soil
fertility.
