STUDY OF PROPERTIES OF VERMICOMPOST BASED ON COW DUNG

Unprocessed waste from agriculture sector, especially animal husbandry, causes of environmental problems. Therefore, efficient use of animal husbandry waste is relevant. In the scientific work, the main substrate is cow manure and its qualitative properties were analyzed. Experiments were carried out to study vermicompost (biohumus). The experiment used cow dung and organic waste (food waste and leaf litter). Cow dung is very rich in macro and micro elements. Accordingly, after the process of vermicomposting in biohumus, a balanced content of elements was determined (N, P, K, Mg, Ni, Cd, Zn, Cu, Cr and etc.). Earthworms absorb unnecessary toxic substances and pathogenic microflora and produce coprolites with useful elements. In the article, for the determination of analyzes, the ultraviolet spectrometric method and optical emission spectrometry with inductively coupled plasma were used. The aim of the work is - to investigate the theoretical and applied aspects of the rational use of the bioresource of technological Californian red earthworms and the potential of the microbial community of organic waste for the development of scientific foundations of vermicomposting and reproduction of soil the fertility.
