Biotechnological Bases of Obtaining Biohumus

Currently, along with the development of agriculture, a certain amount of organic waste is generated from products produced to meet the needs of the population. Organic waste can be recycled with the assistance of earthworms. The technology of processing organic waste using earthworms is of great theoretical and practical importance in solving biotechnological problems. In vermicompost with the help of local earthworms, the content of total nitrogen increased from 0.4 to 0.5%, total phosphorus — from 0.2 to 0.4%, total potassium — from 0.45 to 1.6%, calcium — from 0.15 to 1%, sodium — from 0.12 to 1%.
