Abstract
A slow-release nitrogen fertilizer is disclosed employing proteinaceous animal food materials which are stabilized against decomposition and decay for extended periods of time when stored at ambient temperatures. The treated animal food materials are useful as fertilizer compositions, as food supplements or as bait for fish and crustaceans, such as crab. The animal food material is comminuted together to a finely divided state of the consistency of a thick soup with at least 4% by weight, based on the weight of the animal food material, of a polyol having from 2 to 8 carbon atoms and 2 to 6 hydroxyl groups. Edible polyols are used when the end product is to be used as a bait or food supplement. Anti-oxidants and/or mold inhibitors are also preferably added to the animal food material/polyol mixture. The mixture is further stabilized against decay for extended periods of time when stored at ambient temperatures by incorporating into the mixture a sufficient amount of attapulgus clay to dehydrate the animal food material/polyol mixture. The resulting mixture may be extruded into a shaped form or used in granular form.
