phosphate rock (MPR) has been considered as the most promising alternatives to the expensive mineral P fertilizers in Tanzania. However, slow dissolution of the MPR results into limited availability of P for plant uptake, hence limited first season crop response to applied MPR. Production of phosphate rock enriched composts has. Get Price
