The influence of zinc fertilizer on the yield and quality of alfalfa with different provision of sod-podzolic sandy loam soil with zinc

Abstract

The article presents the results of studies on the effectiveness of the use of zinc fertilizers in the cultivation of alfalfa, depending on the availability of sod-podzolic sandy loam soil with zinc. It has been established that non-root fertilizing of alfalfa with zinc fertilizer is effective only with low availability of mobile zinc in the soil. An increase in the content of protein and zinc in alfalfa plants was noted with an increase in the content of the element in the soil and the introduction of micronutrients.
