Title: Nitride-based controlled-release fertilizers and process for making same

Abstract

A controlled-release solid nitride fertilizer from fly ash and a method for making are described. The fertilizer includes a nitrogen source including at least one solid nitride combined with at least one precipitation-inhibiting agent and with at least one moisture-retention agent, all compressed together to form a porous release structure that in contact with water releases ammonium ions as a nitrogen nutrient at a substantially uniform release rate over a selected release period and thereby maximizes nitrogen-use efficiency by plants.
