Economic efficiency of systems of application of fertilizer in crop rotation at different systems of soil cultivation in North-East Forest-steppe

Abstract

Aim. To examine the economic efficiency of application of organic and mineral fertilization systems of the 4-field rotations under different soil tillage systems. Methods. Field, laboratory and statistical. Results. It was investigated the costs for the application of organic and mineral crop fertilization systems of short crop rotation under moldboard and minimum tillage systems and levels of profitability were calculated. It was defined that the use of mineral fertilizers under such parity of prices that currently prevailing in the agricultural market of Ukraine on some variants of the experiment was unprofitable. Conclusions. It was established that the highest level of profitability of fertilizer application was by mineral and organic fertilizing systems respectively by minimum and moldboard tillage systems - 25.2 and 15.2%.
