Research of the influence of biotechnological methods of organic waste recycling in the production of new bioorganic fertilizers for agricultural crops

The article presents research on the impact of biotechnological methods of processing organic waste on the quality of new bioorganic fertilizers and their impact on agricultural crops. A technological scheme for the production of bioorganic fertilizers with alkaline hydrolysis has been developed. A prototype fertilizer was obtained. The highest yield of humic substances in the production of bioorganic fertilizers was obtained by alkaline hydrolysis at a pH of 8.5. The yield is 8.9% by weight.% for the dry matter of the liquid fraction and 2.8% by weight.% of the dry matter of the solid fraction. The yield is 8.9% mass.% of the dry matter of the liquid fraction and 2.8% mass.% of the dry matter of the solid fraction. Bioorganic fertilizer at a concentration of 10-4%, obtained by bioconversion technology with alkaline hydrolysis at a pH of 8.5, increases laboratory germination and energy of germination by 30% and 11%, respectively, compared to the control. The highest indicators of the effect of liquid bioorganic fertilizer obtained in the technology of bioconversion with alkaline hydrolysis at a medium pH of 8.5 on the growth and development of wheat seedlings. The best growth indicators were observed in wheat seedlings under the influence of bioorganic fertilizer at concentrations of 10-2% and 10-4% for 14% and 23%, respectively. Treatment with a concentration of 10-2% had the greatest effect on the development of the seedling's root system, while treatment with a concentration of 10-4% had the greatest effect on the development of the seedling itself.
