Mechanical activation technique represents a unique process in which the mineral surface reactivity can be increased in addition to having new products. Phosphate is a one of the plant nutrients that can be produced from phosphate rock. However, direct usage of the phosphate rock has several limitations. In this study, the mechanical activation was used to modify the phosphate structure to be suitable for direct use as a natural fertilizer. It seems a better alternative for the highly sophisticated technology used worldwide to produce completely water-soluble fertilizers.
