    Feed The Future Cultivatinghope Through Phosphate Rock

    Sep 17, 2020 Today we are focusing on our joint research on phosphate rock. Current phosphatic fertilizers and fertilizer production processes are inefficient and result in poor use efficiency of phosphate rock, a finite essential resource. In 2010, IFDC estimated that phosphate rock reserves and resources, at current production rates, may last only 350 years.
