The active pool of SOC forms a relatively small portion of total SOC but it plays important roles in maintaining and monitoring soil quality. Soil samples were collected from three depths with two replications in June, 2018. The collected soil samples were subjected to analyses for physico-chemical properties such as particle size analyse, pH, EC, soil organic carbon, available phosphorus and potassium and permanganate oxidizable organic carbon. We measured POXC by spectrophotometer using 0.02 M KMnO4 at 550 nm light. POXC was from 0.7 to 7.7 % of SOC in our study. POXC is a good indicator of soil organic fraction in environmental monitoring programmes for arid environments. POXC determination is relatively simple and promising method that could be adopted by soil test laboratories for use in routine soil samples. Permanganate oxidizable C (POXC; i.e., active C) is a relatively new method that can quantify labile soil C rapidly and inexpensively.
