Abstract

This paper compares the recovery of the residual P2O5 from magnesium thermophosphate (MPT) with different granule size, and from granular ordinary superphosphate(OSP). Seven successive crops were grown in pots in a greenhouse and their phosphorus content was analysed. Results demonstrated that powder MTP has the same residual effect as OSP. Coarse MTP, however, caused lower recovery of residual phosphorus.
