Rock phosphate represents an alternative phosphate source. In the present study conducted in a greenhouse, a core collection of six hundred ninety four cowpea accessions was evaluated for phosphate-deficiency stress tolerance and for efficiency of utilization of P from rock phosphate. Plants were grown for 8 weeks in Nacogdoches pine forest soil.
Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.This occurs through washing, screening ...
