Indigenous knowledge of soil fertility management in the humid tropics of Arunachal Pradesh

Traditional ecological knowledge has been established to have a bearing on natural resource management by the indigenous communities living in biodiversity rich North eastern hill region. The present study correlates the indigenous knowledge and scientific knowledge in assessing the nutrient availability status of the agricultural soil as practiced by the ‘Nyishi’ tribes who use visual properties such as colour, texture and topographic positioning of land/terrain.
