Phosphorus Leaching in an Acid Tropical Soil “Recapitalized” with Phosphate Rock and Triple Superphosphate
Gikonyo, Esther Wakiuru and Abdul Rahman, Zaharah and Musa, Mohamed Hanafi and Abd Rahim, Anuar (2010) Phosphorus Leaching in an Acid Tropical Soil “Recapitalized” with Phosphate Rock and Triple Superphosphate. The Scientific World Journal, 10 . pp. 1498-1508. ISSN 1537-744X
“Phosphorus recapitalization” involves application of high phosphorus doses that could lead to P losses through leaching. Phosphate leaching was therefore tested on soils “recapitalized” with triple superphosphate (TSP) and Gafsa phosphate rock (GPR), but results of this work indicated there was high leaching in TSP treatments, particularly when it was integrated with manure, but there was no significant leaching in GPR even with manure integration. It is therefore agronomically and environmentally suitable to use PRs for “P recapitalization”.
