Abstract: A study was conducted to investigate the phosphorus status of Tehsil Kahuta of district Rawalpindi. A total of ninety composite soil samples were collected from different sites. Out of ninety, 78 samples (87%) were found of poor (<5 mg k kg -1soil) level while 11 samples (12%) had satisfactory (5-10 mg k kg -1soil) level and 1 soil sample (1%) was found with adequate (> 10 mg k kg -1soil). The maximum phosphorus content 10.5 mg k kg -1 soil was recorded in Loona Kahuta site while minimum phosphorus 2.0 mg k kg -1 soil was recorded in Kalar Saidhan site.
