الروسية. В исследованиях на дерново-подзолистой супесчаной почве установлено, что снижение доз фосфорных и калийных удобрений с учетом содержания фосфора и калия в запаханной соломе кукурузы обеспечило урожайность семян подсолнечника на уровне полных доз минеральных удобрений при снижении затрат на удобрения на 50 USD/га. В вариантах с внесением N90P60K120 под подсолнечник дополнительное внесение азота по соломе неэффективно и позволяет сэкономить 27 USD/га без снижения урожайности.

In course of the research there were studied the various date and forms of additional nitrogen application in corn straw and doses of potassium and phosphorous fertilizers. The research was realized in the conditions of the Republic of Belarus on sod-podzolic sandy loam soil in 2012-2013 in State enterprise ‘Experimental base named after Suvorov’ (Uzda, Minsk region). As a result of realized research there was revealed that decrease doses of phosphorus and potassium fertilizers with regard to the content of phosphorus and potassium in straw plowed corn (Zea mays) provided the yield of sunflower (Helianthus annuus) seeds at the level of full doses of mineral fertilizers by reducing the cost of fertilizer at 50 USD/ha. In versions with application of N90P60K120 under sunflower additional nitrogen in the straw was inefficient and saved 27 USD/ha without reducing yields.
