Assessment of soil resource characterization along the Toposequence of Koranahalli Subwatershed, Chikmagalur district, Karnataka

A detailed soil survey was conducted to characterize soil properties and classified the soils along the toposequence Koranahalli subwatershed of Tarikere taluk, Chikkamagaluru district at cadastral scale was carried out by using remote sensing and GIS techniques. One hundred and fifty-six profiles were studied for the morphological, physical and physico-chemical properties. Fourteen soil series were identified, all the pedons were characterized by shallow to very deep in depth. The texture of the soils was sandy clay loam to clay. The consistence of pedons varied from moderately to very sticky and moderately to very plastic. pH and CEC of the soils increases as the depth of the soil increases. The organic carbon content of pedons ranged from 2.20 to 8.70 g kg-1, low to medium content was observed in most of the soil series. Soils studied were classified up to family level according to revisions in soil taxonomy.
