Widorokandang Village, Magetan Regency, East Java has potential in agriculture and animal husbandry. The problems faced in agriculture are about the price of fertilizers and the use of inorganic fertilizers in the long term. The alternative of reducing the use of inorganic fertilizers by using organic fertilizers can help to improve soil structure and good nutrients. This is supported by the existence of a rabbit farm in Widorokandang village which produces rabbit urine waste as the main ingredient for making liquid organic fertilizer. The process of making liquid organic fertilizer is done by fermentation which is easy for the community to do. IPB KKN-T students together with rabbit breeders in Widorokandang village made a liquid organic fertilizer product "Growi". This product is expected to help overcome fertilizer problems in Widorokandang village and improve the community's economy. The relative profit value of the "Growi" liquid organic fertilizer business has a value of more than 1 which is a feasible business.
