Vermicomposting of Organic Waste with Eisenia fetida Increases the Content of Exchangeable Nutrients in Soil

BACKGROUND AND OBJECTIVE: Vermicomposting is a green technique used to produce organic compost from organic waste with the aid of specific earthworm species. The resulting compost is rich in nutrients that can improve plant health and fertility. This study was conducted to produce organic compost using a developed vermicomposting technique. And that is to enhance and increase the exchangeable nutritional content in the soil for utilization in sustainable agriculture. MATERIALS AND METHODS: The experiment was carried out with Eisenia fetida worms in a treatment technique using sugarcane straw, remnants of garden tree leaves, kitchen wastes and cow manure. The physiochemical parameters, namely temperature, moisture, acidity, electrical conductivity and 10 different nutrients, were assessed in vermicompost samples and garden soil sample (without earthworms). RESULTS: The results revealed higher N, C and P content in the vermicompost than in the garden soil sample. CONCLUSION: This study confirms that vermicompost has a high nutrient value and can be considered a promising method for safely disposing organic waste, improving crop production and achieving long-term food security.
