Тhe study of the biological activity of humic substances of peat as growth-stimulating drugs

Humic substances are a group of high-molecular biopolymers that are formed during the natural decomposition of plant and animal tissue. Due to their functional composition, humic substances of peat have a sufficiently large range of biological properties, they are quickly involved in the metabolic processes in plants. The use of humic substances as micronutrients leads to increased resistance to adverse factors, the development of the root system, improves the synthesis of chlorophyll, which increases the yield and quality of cultivated plants. The paper considers the influence of natural biopolymers such as humic substances of peat on the growth and development of agricultural plants of oats and peas. It has been established that the composition of humic substances includes various functional groups (phenolic and aliphatic hydroxyls, carboxylic, quinoid), which determine the biological and growth-stimulating effect. It has been shown that solutions of humic substances used in the experiment have a beneficial effect on seeds even in small concentrations. The purpose of this research work is to study the biological activity of humic substances of peat as growth-stimulating drugs of agricultural crops
