Abstract
In studies on sod-podzolic sandy loam soil found that lower doses of phosphate and potash fertilizers with regard to the content of phosphorus and potassium in the straw plowed predecessor had ensured the grain yield of oats at the level full doses of mineral fertilizers by a lower cost for fertilizers on 15 USD/ha, or 16 %. The use of compensatory nitrogen dose on straw of buckwheat in the form of urea provided an increase of grain yield of oats on 3,1 c/ha in the spring application and 2,5 c/ha in autumn. The highest grain yield (21,4-25,1 с/ha) was obtained in the organic-mineral system of fertilizer.
