ACTION AND CONSEQUENCE OF LIME AGAINST THE APPLICATION OF MINERAL FERTILIZERS ON THE PRODUCTIVITY OF CROPS IN THE ROOT LINK

Abstract

The article presents data from field experiments to study the effect of lime ameliorant and mineral fertilizers on the productivity of crops on leached chernozem. The use of limestone flour as a chemical ameliorant against the background of the use of different doses of mineral fertilizers and in its pure form increases the yield of the first crop by 8.0-52.7%, the yield of the second crop by 17.2-51.0 %, and the third by 1.6-68.5%. The effectiveness of mineral fertilizers in the third year against the background of liming increases in comparison with the first and second years of their action. The highest productivity was obtained on variants with the use of complex mineral fertilizers against the background of liming with norms of 1.5 and 2.0 Ng.
