Title: Processes for preparing granular composite fertilizer compositions and products produced thereby

Abstract: Granular composite fertilizer compositions are prepared by applying a liquid mixture of urea and formaldehyde to a dry substrate such as a phosphorus source, a potassium source, a secondary nutrient source, a micronutrient source or mixtures thereof and reacting the liquid mixture in situ to form methylene urea reaction products which promote binding of the substrate into a granular composite while granulating the substrate at the same time that the liquid mixture reacts in order to form the granular composite fertilizer compositions.
