A study was undertaken to characterize and classify the soil resources of Kumachahalli micro-watershed in Chamarajanagar district of Karnataka. Sixteen profiles were studied for the morphological, physical and chemical properties. Seven representative pedons covering all the soil types were selected and classified. Soils were very shallow, deep and moderately deep in depth. The colour of the soils in the pedons varied from dark red to dark reddish brown. Soils were loamy sand, sandy loam, sandy clay loam and clayey in texture. The structure was fine granular to sub-angular blocky throughout the profile. The consistency was very friable in surface horizon and friable in sub-surface horizons under both dry and moist conditions. Soil reaction of the pedons varied from near neutral to moderately alkaline in nature. In valley lands, the soil reaction was neutral to slightly alkaline. The electrical conductivity of all the pedons was negligible. Calcium and magnesium are dominant exchangeable cations followed by sodium and potassium. Soils studied were classified up to family level according to revisions in Soil Taxonomy. Major proportion of the soils in the micro-watershed belonged to the order Alfisols and Inceptisols.
