Assessment of balance of nutrients of grain-potato crop rotation at traditional and alternative fertilizer system

Abstract

Goal. Under the conditions of radioactive contamination in central Polissya, the influence of traditional and alternative fertilizer systems on the fertility of turf and podzolic soils and the productivity of short-rotation grain grazing crop rotation are to be determined. Methods. Field, analytical, bioenergy. Results It is established that traditional and alternative fertilizer systems in crop rotation have a positive balance of phosphorus with intensity of 128 - 248% and potassium 128 - 202%. Conclusions The positive influence of organomineral fertilizer system on the soil fertility and crop rotation crops irrespective of the type of organic fertilizer was noted. Traditional organo-mineral fertilizer systems in comparison with alternative provide a much higher level of productivity of short-rotation crop rotation.
