The literature comparing the efficiency of partially acidulated phosphate rock fertilisers with that of a single or triple superphosphate is briefly summarised and found to be conflicting. Various theories purported to explain why partially acidulated phosphate rock products are as efficient are examined. An alternative hypothesis, which appears to reconcile the conflicting evidence, is presented. This depends in part on the dissolution of the phosphate rock component of a partially acidulated… CONTINUE READING
