Abstract
This article examines trace elements that regulate the functional activity of living organisms, are part of tissues, enzymes, hormones involved in the synthesis of carbon, fats, proteins, vitamins and other substances. In addition, trace elements allow plants to withstand adverse weather conditions, have a positive effect on the absorption of nutrients and water by the body. It is shown that trace elements play a special role in increasing the efficiency of mineral fertilizers and increasing the yield of agricultural plants. Special attention is paid to elements such as zinc, copper, manganese, boron, molybdenum, cobalt and iron, since even their minor deficiency in the soil can become a limiting factor for plant growth and development.
