Granular fertilizer has a very beneficial effect on plant growth, by regulated release of nutrients, by avoiding washing away of fertilizer salts, and by making NPK application uniform. Poor storage conditions and long storage without conditioning result in formation of lumps and powder thereby the benefits of granulation/prilling are largely lost by non uniform application, washing away of powdery fertilizer, and also making mechanical application of fertilizer impossible. This poor conditioning can lead to a sizable percentage reduction in yields of the farm; all this when a considerable amount of capital is deployed and cost is incurred in NPK/urea plants especially to provide granular/prilled product.
