The researchers aimed to make vermicompost richer in nutrients by adding cow manure and organic supplements like egg shells, bone meal, banana peels, and tea waste to aquatic plants. They found that this enriched vermicompost had higher levels of nutrients like nitrogen, phosphorus, and potassium. Earthworms in the enriched vermicompost grew better, reproduced more, and showed improved activity. The enriched vermicompost was stable and mature, making it suitable for use in agriculture to help crops grow better.
