Soils Found in Northeast India - Classification, Distribution and Erosion

By
Northeast India is a place of heavy rainfall, high relative humidity, and high temperatures, which cause rapid weathering of rocks. As the weathering of surface rocks of the hills and mountains proceeds, the sheet flood caused by heavy rainfall removes the weathered materials and carries them down to the headward streams of the rivers.  The rapidly flowing rivers then carry the sediments, big and small, down to the foothills and plains. Soils found in northeast India are mainly four major groups. These are Alluvial Soil , Red Soil , Laterite Soil , and Mountain Soil . In the Northeast Region , soil and environmental degradation is a big problem. This is further aggravated due to ecologically unsuitable shifting cultivation by the local tribes/ indigenous people who are socio-culturally and economically very much attached to this form of land use.
