ЭФФЕКТИВНОСТЬ ХЛОРИСТОГО КАЛИЯ В ЗАВИСИМОСТИ ОТ ОБЕСПЕЧЕННОСТИ ПОЧВ КАЛИЕМ

Abstract

The effectiveness of using potassium chloride to potato depends on the availability of exchangable cadium in the foothills dark chestnut soil. The application of potassium chloride K35-105 on the background of nitrogen and phosphorus fertilizers will provide yield increase from 2,3 to 7,31 /ha in the content of exchangeable potassium in the soil from 320 to 420 mg / kg, and the increase of the level of exchangeable potassium soil significantly reduces the yield increase.
