Soluble phosphate availability is a major limiting factor for plant growth, development, and yield. To assure a constant phosphorous supply, plants employ both high- and low-affinity phosphate acquisition mechanisms. ...

Objective: The aim of this study was to evaluate the availability of P in soil and straw during successive tropical grasses crop fertilized with different phosphates. The crops were grown in 18 dm-3 pots for 50 days. ...

Forty two soil isolates (31 bacteria and 11 fungi) were studied for their ability to solubilize rock phosphate and calcium phosphate in culture medium. Eight bacteria and 8 fungi possessed solubilizing ability. Pseudomonas ...
