Measurement of Soil Organic Matter in Different Lithology of Karachi

Ghulam Abbas, Rizwana Aleem Qureshi and Sohail Jamil Qureshi

ABSTRACT

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.
