APPLICATION OF ENVIRONMENTALLY SAFE WATER-CONSERVATING MATERIALS IN BARLEY AGROTECHNOLOGY IN THE BSR

The sorbent developed for the research is based on the introduction of biodegradable units into the macrochain at the stage of synthesis of polymers. The sorbent granules, containing biodegradable fragments in the mesh structure, were obtained by radical polymerization in the redox environment. Humic acids, microorganisms, microelements were introduced into the sorbent matrix. It also seems effective to use a whole complex of products for processing vegetable and animal raw materials containing starch, pectin, chitosan and other polymeric materials. They are both available and can be decomposed as the result of microbial activity into water, carbon dioxide and nitrogen derivatives. The purpose of this work was to study the effect of moisture-retaining materials on the yield of barley. All the types of sorbents demonstrated the ability to absorb and retain moisture in the plant root area, which allowed an increase in the barley crop production. The data showed that due to the moisture retained inside the sorbent and the moisture released to the plants, it was possible to form an additional barley crop. The chosen dose of the sorbent (20 kg / ha) increased the yield production by 1.9. The maximum yield output in the pilot plots was 2.5 times as high as that of the control variant. It is accounted for the contrast between the moisture intake and its content in the soil. The biological activity of the soil varied considerably at the experimental plots, and the figures for the catalase activity were discovered 1.1-1.5 as high as the control option. We could observe a tendency of the increase in its activity by the end of the vegetation season.
