Extensive studies have been carried out to assess the organic matter status of soil in different soil types in Balochistan for the provision of guidelines to farmers and researchers for better crop production. Different soil types of the area were collected, analyzed and classified for organic matter, pH, and density, hydrogen, oxygen, sulphur and nitrogen contents. Organic matter is essentially required for plant growth but its contents vary in different soil types. By looking at the table it is clear that the nitrogen is higher in sandstone (0.90%) with weak acidic condition (6.90). Sulphur contents are higher in sandy limestone (1.0%) while minimum in limestone (0.00%). Oxygen contents are higher in sandstone (18%), which is considered to be suitable for plant growth as it has low conductivity and weak acidic pH. Organic contents are higher in shale stone. Fertilizer recommendations were advised to the farmers according to soil conditions.
