Researchers used a special type of earthworm to turn sugar industry waste into a valuable fertilizer. By adding cow dung and other organic materials, they created ten different types of vermicompost. After 14 weeks, the earthworms increased the levels of nitrogen, potassium, and phosphorus in the waste. The earthworms also helped decrease the C:N ratio, making the fertilizer more effective. The vermicompost with the highest earthworm activity showed the best results, with increased biomass and cocoon production. Overall, this method can efficiently manage sugar industry waste and produce high-quality vermicompost.
