High coefficients of correlation (R=0,822 0,912) speak about authentic effectiveness of applied fertilizers in the rate N60P120K20 ; N60P120 K60. Content of movable phosphates in soil under application of duplex and triplicate rates of phosphor fertilizers separately and in combination with nitric and potassic fertilizers is increased.
