EVALUATION OF THE CHEMICAL COMPOSITION OF LEGAL MULTI-YEAR HERBS REDUCED IN THE CONDITIONS OF POLLUTION OF AGRICULTURAL HERITAGE BY HEAVY METALS

Abstract

The article is devoted to the study of the influence of heavy metals on the chemical composition of the green mass of legume perennial grasses. The accumulation of long-term grass beans with such heavy metals as lead, cadmium, copper and zinc was studied. It is established that the lowest amount of heavy metals in the green mass is accumulated by white clover, and the largest one is gazelle East. The analysis of the chemical composition of the green mass of legume perennial grasses for the content of heavy metals and nutrients. It is established that all the studied types of leguminous perennial grasses are characterized by an increased and balanced content of basic nutrients in conditions of contamination of lands with heavy metals. The regularity of nutrient decrease in feed with increasing concentration in plants of heavy metals is revealed. The most nutritious food in terms of chemical composition in conditions of soil contamination with heavy metals was white clover. A rectilinear relationship between the concentration of cadmium and the proportion of dry matter and BEP in the chemical composition of legume perennial grasses was established
