2 Agricultural chemistry is the science that studies the circulation of substances in the system "soil plant fertilizer", as well as their impact on the quality of agricultural products and problems of environmental protection in the area of management of agricultural sector of the state economy. Agrochemical research relate to the reproduction of soil fertility, efficient use of mineral, organic fertilizers and microelements on the background of other chemicals, the study of agro- chemical, economic, energy and environmental efficiency of fertilizers, their physico-chemical and agrochemical properties, the organization of the system of chemicalization of agriculture branches.
