The feasibility of using calcium ammonium nitrate for the preparation of fertilizer mixtures has been investigated. Twelve different mixtures were prepared and studied under different periods of storage, under varying conditions of relative humidity and with different sources of phosphorus and fillers. It was observed that CAN can be used in the preparation of NPK mixtures provided these are not stored for long, and kept in alkathene lined gunny bags under lowered atmospheric humidity. High relative humidity, less water soluble source of P as bone meal and fillers like limestone decreased the effectiveness of NPK mixtures containing CAN.
