【 摘 要 】

The aim of this study to examine the total number of phosphate solubilizing bacteria in the soil around the reservoir C and F and the surrounding environmental conditions. Calculation of the amount of phosphate solubilizing bacteria using pikovskaya medium. The number of bacteria that have a clear zone is calculated based on the amount of dilution. The results showed that the amount of soil phosphate solubilizing bacteria from C and F Reservoir amounted to 36.5x 104 and 14.2 104 cfu/g, respectively. An Environmental condition such as rain rates, air temperature and humidity around ITERA do not support an increase in the amount of phosphate solubilizing bacteria. It can be seen from the data on environmental conditions that are not in accordance with the conditions of soil microbial growth.
