In course of the research there was studied comparative efficiency of application of new and traditional composts at winter wheat (Triticum aestivum) cultivation on sod-podzolic light loamy soil. The research was realized in the conditions of the Republic of Belarus in 2009-2011. As a result of realized research it was revealed that the highest productivity of grain of winter wheat (73.0-74.0 t/ha) with the best indexes of quality and profitability of fertilizers application 52-58% is received in variants with organic-mineral fertilizer system. The recoupment of 1 t of the entered composts at organic-mineral fertilizer system differed insignificantly and on the average made 27.9 kg of winter wheat grain, 1 kg of operating substance of mineral fertilizers – 9.8 kg of grain. Better quality grain at higher gathering of digestible protein (695-713 kg/ha), fodder (87.6-88.8 c/ha) and fodder-protein (85.8-87.2 c/ha) units was obtained in variants with organic-mineral fertilizer system. The content of crude and digestible protein in winter wheat grain in these variants, reaching on the average 13.0 and 11.2% accordingly, was essential above concerning a variant without fertilizers. Specific carrying out of nutrients from 1 t of winter wheat grains and corresponding quantity of collateral production practically did not change by variants and has averaged by experiment: nitrogen – 22.5 kg, phosphorus – 9.9 kg, potassium – 17.6 kg, calcium – 2.1 kg, magnesium – 2.1 kg.
