The researchers studied how earthworms can turn garden waste and cow dung into valuable compost. They used Eisenia foetida worms in a 180-day experiment and checked the changes in the compost every 45 days. The compost pH decreased from 9.4 to 7.8, while organic carbon and C:N ratio also decreased. On the other hand, nitrogen levels increased, including ammonical and nitrate nitrogen. Phosphate and potassium levels also increased. This shows that vermicomposting can efficiently convert organic waste into a useful product.
