Efficiency of The Vermicomposting Process Using Californian Red Worms (Eisenia Fetida) And Analysis of The Agrochemical Properties of The Resulting Biohumus

This article investigates the efficiency of the vermicomposting process and the agrochemical properties of biohumus obtained from various organic substrates. The results demonstrated a significant increase in the content of organic matter (43.60–47.4%) and nutrient elements in comparison with the control variant during the vermicomposting process. The highest nitrogen content was identified in biohumus produced from cattle manure (2.31%), the highest potassium content in biohumus obtained from sheep manure (4.91%), and the highest phosphorus content in biohumus derived from poultry manure (2.49%). The research findings revealed a direct relationship between the chemical composition of biohumus and soil fertility. In addition, the balanced ratio of nutrient elements was found to be an important factor in the formation of the soil chemical environment.
