Abstract

The present study was conducted to assess the physico-chemical characteristics of selected areas and to compare the different methods of organic matter determination. Soil samples were collected from different areas of Rawalpindi and Fateh Jang for the estimation of soil texture, soil pH, electrical conductivity, saturation percentage and available sodium and potassium contents and for the comparison of routine method of organic matter determination with the active organic matter determination method. A total of 24 composite soil samples were collected from six locations, Fateh Jang, Adiayla, Taxila, Swan, Kahuta and Gujar Khan. These soil samples were analyzed. All the samples were loam in texture. Soil pH values of all less than 8.0 and electrical conductivity of all soil samples was normal except Taxila which showed very high salt deposition. Available sodium was satisfactory while in available potassium, 42% samples were satisfactory and 58% were adequate. Comparison of both methods of organic matter estimation is not a true presentation of organic matter contents of soil.
