Assessment of Macro and Micro Nutrients of Soil in a Small Agricultural Watershed

This study deals with the determination of various topographic parameters and characteristics of micro & macro nutrient of soil sample existing in the Sandhari nala watershed. The specific locations of various soils sampling area situated at different villages of watershed were identified using Global Positioning System (GPS). Soil samples collected from different locations of the watershed were analyzed for their macro (N, P, K) and micro (zinc, iron, copper, manganese) nutrients. The availability of nitrogen and phosphorus was found to be low in almost all soil samples, whereas the availability of potassium was found medium rang. The availability of micro nutrient (zinc, copper, iron) was found to be in critical level in almost all soil samples. The data reveals that in soils are deficient in N, P, & K which requires addition of extra fertilizer and manures to make it suitable plantation and increase their healthy growth.
