Phosphate Mineral as Fertilizer in Saline Soil

摘要：

Certain types of rock phosphates of sedimentary origin are applied to acidic soils as fertilizer directly.Recent research in India showed that high grade rock phosphate in fine size when used as a mix with organic manure works as efficiently as di-ammonium phosphate (DAP) in alkaline soils.The rock phosphate from Jhamarkotra,India (sedimentary origin),Egypt (sedimentary origin) and South Africa (volcanic origin) showed good agronomic efficiency when used as Phosphate Rich Organic Manure (PROM).Further PROM shows equal residual effect.The results of efficiency of PROM made using two grades (+ 24% P2O5 and 34% P2O5) of rock phosphate mineral from Jordan show that low grade rock phosphate slimes are as effective as high grade phosphate concentrate when used in PROM.Also PROM is very effective in the saline soil of Eshidiya desert where DAP is not at all effective.
