Pramod Tumbal, P.L. Patil

Abstract


A study was undertaken to characterize and classify the soil resources of Balapurmicro-watershed in Koppal district of Karnataka. Seventeen profiles were studied for the morphological, physical and chemical properties. Ten representative pedons covering all the soil types were selected and classified. The soils were very shallow to deep in depth, dark reddish brown to yellowish red in red soils, where as in black soils shown very dark brown to very dark grey brown in colour. Soils under the study were predominantly sub-angular blocky in structure, sandy clay to clay in texture, neutral to slightly alkaline in reaction with non-saline soils and organic carbon content was low. Calcium and magnesium were the dominant exchangeable cations followed by sodium and potassium. Soils studied were classified up to family level according to revisions in Soil Taxonomy using morphological, physical and chemical properties. Major proportion of the soils in the micro-watershed belonged to the order Inceptisols, Alfisols and Vertisols
