Occurrence of phosphate-solubilizing bacteria in some Iraqi soils
The phosphate-solubilizing bacteria (PSB) were enumerated in 52 soil samples collected from agricultural areas at Baghdad. The results revealed that more than 90% of the samples were inhabited with indigenous PSB. The number varied and ranged from 0.012-28.4 × 10⁴ cell g⁻¹ soil. The correlations bet...

Zusammenfassung: | The phosphate-solubilizing bacteria (PSB) were enumerated in 52 soil samples collected from agricultural areas at Baghdad. The results revealed that more than 90% of the samples were inhabited with indigenous PSB. The number varied and ranged from 0.012-28.4 × 10⁴ cell g⁻¹ soil. The correlations between PSB counts and electrical conductivity, available phosphorus, cation-exchange capacity, soil moisture, organic matter and pH were insignificant. Both abundance and numbers of PSB were more pronounced in descending order under vegetables, legumes, grasses, cereal and orchard trees. |
