Abstract
In studies on sod-podzolic sandy loam soil found that lowering doses of phosphate and potash fertilizers with regard to the content of phosphorus and potassium in the straw plowed barley had ensured the grain yield buckwheat at the level of full doses of mineral fertilizers by a lower cost for fertilizers on 17 USD/ha, or 17%.The use of compensatory nitrogen dose on plant residues of the precursor in the form of urea provided an increase grain yield of buckwheat on 3,5 c/ha in the spring application and 1,7 c/ha in autumn. In the variants with the NPK application under buckwheat additional amounts of nitrogen on straw increased yields an average of 2,8-3,2 c/ha.
