Role of Bacterial Inoculation in Kinetics of Phosphorus Release from Phosphate Rock in Calcareous Soil.

摘要

ABSTRACT Biological experiment was conducted to study role of Bacillus ceares inoculation in phosphorus release from phosphate rock (Ca10(PO4)6(OH)2) and to evaluate the phosphorus supplying powder of a calcareous. A loamy soil was collected from College of Agriculture field (Al-Gadria), University of Baghdad. Bacterial isolates were obtained onto phosphorus and used to release phosphorus. The soluble phosphorus was determined at 0, 10, 20, 30, 40 and 50 day of incubation. The results showed th.
