Abstract:
The clays are among the most important soils of the world. The clay minerals are important for construction, pottery and ceramic items. As clays are materials originated from decomposition of rocks made up of clay minerals and non-clay minerals, their applicability depends on their chemical and mineralogical compositions. With an aim at studying the clay types and applicability of the clays of Manipur in general and that of Thongjao s/c village and Nongpok Sekmai village in particular, the study has been done. During the period of survey samples were collected from different sites in large scales from each of the villages in different depths. These clays have pH values ranging from 4.5 to 6.9 and are found to contain 0.67% to 3.547% organic carbon, 260 to 565 Kg per Hectare of Nitrogen and 22.4 to 78.5 Kg per Hectare of potassium. The clays were analysed using the Energy Dispersive X-Ray Spectroscopy (EDXS) after heating in order to remove moisture, Scanning Electron Microscope (SEM) and identified their chemical components. The study may contribute valuable information in the practices leading towards sustainable development that may enhance and promote economic well-being of the community in the area.
