Abstract: The selected microwatershed belongs to Kollegal taluk of Chamarajanagar district. The microwatershed lies 20 km away from Kollegal taluk head quarter. The Micro-watershed is located between 120 6' 34.5 and 120 7' 49.6 N latitude, 770 15' 30.9 and 770 14' 20.2 E longitude, with an average elevation of 775 m above Mean Sea Level (MSL). It occupies a part of the four villages viz. , Kannuru, Anapura, Mangala, and Kamgare. Composite soil surface sample in strategic manner to cover all farming systems of the watershed. Upland soils was slightly acidic to neutral, lowlands soil reaction was neutral to slightly alkaline. The electrical conductivity of all the fertility points was negligible, The organic carbon content vary between low to medium, The cation exchange capacity of the soil varied from low to medium. The available nitrogen, phosphorus and potassium were low, low to medium and medium respectively and fertility maps of all nutrients prepared

Keywords: Microwatershed, Remote Sensing RS tools, cation exchange capacity, GPS, physiographic units
