从巴格达农业区采集了52个土壤样品，对其中的解磷细菌进行了计数。结果表明，超过90%的样品与土著光合细菌居住。其数量变化范围为0.012-28.4×104个细胞g−1土壤。光合细菌数与电导率、有效磷、阳离子交换量、土壤含水量、有机质和pH值的相关性不显著。无论是丰富的和数量的光合细菌更明显的降序蔬菜，豆类，草，谷物和果园。
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.
