ABSTRACT:
A new method of preparing granular slow release nitrogen fertilizer, exhibiting substantially complete nitrogen availability as a plant nutrient, from nitrogenous organic wastes, such as animal excretia, by coreacting particulate dry conditioned nitrogenous organic waste and reactive ureaformaldehyde oligomer; and the slow release fertilizer exhibiting improved nitrogen availability prepared by the new method. The preconditioning of the waste and the preparation of the reactive oligomer are arranged so that the method for forming the new composition is effectively carried out in a damp dry, free flowing particulate system. Parameters are provided for: dry conditioning the wastes, oligomer forming, coreacting, and granulating.
