Evaluation of phosphorus concentration in soil by using spectrophotometer (UV )

Abstract

This study was carried out in the Sirte region, which is located 450 km east of the Libyan capital, Tripoli. During this study, 15 different agricultural soil samples were taken at a depth ranging between (0-20 cm) from 15 sites in Sirte region were evaluated in order to evaluate some natural and chemical parameters such as mechanical analysis and acidity, as well as images and phosphorous concentration in soil (available phosphorous). In this study, a single-beam UV spectrophotometer was used to estimate the absorbance of phosphorous. Through the analysis processes that were reached and estimation of some concentrations of phosphorus, it was found that several samples contain a high percentage of phosphorous, and several of them contain a low percentage, and the majority of samples range from medium to the last, which are considered suitable for global standards
