EFFECT OF MINERAL FERTILIZERS ON CROP YIELD AND QUALITY OF A CROP ROTATION LINK DEPENDING ON THE CONTENT OF MOBILE PHOSPORUSIN SOD-PODZOLIC LIGHT LOAMY SOIL
The optimal rates of fertilizers for spring rape, barley and oats had been found in the field experiments on Podzoluvisol loamy soil with two contrast contents of mobile phosphates. The crude protein content in the harvested crop products was determined, as well as removal of main nutrients per unit of grain yield.
