Abstract
In researches on sod podzolic light loamy soil the application of mineral and organic fertilizers has provided high indicators of agronomic and power efficiency. Entering of mineral fertilizers has raised efficiency of field crop rotations on 19,9-30,3 tha -1 of f.u., as well as entering of organic fertilizers on 5,2-10,8 tha -1 of f.u. at a recoupment of 1 ton of manure of 65,0-131,3 f.u. and 1 kg of NPK of 8,1-9,7 f.u. Power return of application of mineral fertilizers in crop rotations has made 1,16-1,32, and of organic fertilizers 1,21-1,80.
