Abstract


Questions persist regarding the best phosphorus (P) sources for tropical soils, especially for forest species. We evaluated the effects of four different P sources (single superphosphate -SSP; triple superphosphate -TSP; Arad reactive rock phosphate-ARP and Yoorin thermophosphate -YT) on nutrients accumulation, phosphorus use efficiency and growth on mahogany (Swietenia macrophyllaKing.)Mahogany is responsive to P fertilizer, however the high water soluble(TSP and SSP)and citric acid (YT) phosphorus sources had a similar effect on mahogany growth. It suggests that the seedlings producer can use any of thembut should avoid the use of the ARP source in this stage of plant growth.
