IMPROVED FERTILIZER SYSTEM SUNFLOWER WHEN CULTIVATING WITH CORN STRAW PLOUGHING ON SOD-PODZOLIC SANDY LOAM SOIL
Abstract
In studies on sod-podzolic sandy loam soil found that decrease doses of phosphorus and potassium fertilizers with regard to the content of phosphorus and potassium in straw plowed corn provided the yield of sunflower seeds at the level of full doses of mineral fertilizers by reducing the cost of fertilizer at 50 USD/ha In versions with application N60+30P60K120 under sunflower additional nitrogen in the straw inefficient and saves 27 USD/ha without reducing yields.
