In the conditions of the Republic of Belarus there was realized economic evaluation of efficiency of fertilizer application for spring wheat (Triticum aestivum) of Toma variety on sod-podzolic light loamy soil grown in crop rotation. It is established that on sod-podzolic light loamy soil with increasing phosphorus and potassium contents agronomic (payment 1 kg NPK 9,2 kg grain), economic (profit 14%, net income 14,2 USD)and energetic (energy return 3,30 units) substantiated of spring wheat fertilizer system there is the application of N60P30K60. Using in the main application N60P60K120 and double nitrogen top-dressing: N30 in the stage of the first node and N30 in the stage of the last leaf was obtained the largest (67,6 centner/ha) grain yield of 2 quality grade. There is the profit amounts to 6%, the total profit from 1 hectare 10,4 USD.
