In the U.S., there are more than two dozen organic fertilizer companies that sell a wide range of organic fertilizers. Organic fertilizers can be classified into three main categories: animal waste, sludge, and vegetable oil. Animal waste is any waste resulting from the castings of animals, including blood, milk, urine, and other excrement. Sludge is any solid material left over from vegetable production, including sewage sludge, industrial waste, and factory waste. Vegetable oil is any by-product produced from the oil production process, including lye, salt, soap, and fertilizer.
