Management of some aquatic weeds through vermicomposting

The experiment showed that noxious aquatic weeds like water hyacinth, water lettuce and cattail could be managed beneficially by converting easily in to good quality vermicompost within 2 to 3 month using Perionyx excavates earthworms. These composts recorded 0.71-1.36% total nitrogen, 0.38-0.75% total phosphorus and 0.86-1.44% total potassium, indicating its good quality as organic fertilizer.
