Different soil types of the area were collected, analyzed and classified for organic matter, pH, and density, hydrogen, oxygen, sulphur & nitrogen contents. Organic matter is maximum in shale (1.10 %), which falls in the poor category, having pH weak alkaline (7.4). Nitrogen is higher in shale sand (1.68%), which is alkaline (7.4) is considered as best for normal plant growth. Sulphur contents are higher in clay stone (3.20 %). Fertilizer recommendations were advised the farmers according to soil conditions.
