Abstract

Maximum productivity of the crop rotation 146,0-161,2 c k. ed. /га on both level of acidity sod-podzolic loamy sand soil of ground was formed when contributing 20 т/га manure KRS + N75P70K120 + microelements. The сontents of rolling phosphorus increased in arable layer on 20-45 mg/kg. Using the potassium fertilizers at a rate of 100 and 130 kg/ha did not compensate stand bear potassium agricultural culture.
