Abstract: A detailed soil survey was carried out in Sigehadlu micro watershed Kadur taluk, Chikkamagaluru district of Karnataka at 1:50,000 scale. The Sigehadlu micro-watershed was selected to study and understand the pedogenic characters of the soil in different physiographic regions for summit, undulating hills, side and foot slopes due to the variability in landform which affects the crop productivity. Ten soil series were identified in the study area based on the pedological investigations of typifying pedons and physico-chemical properties. The soils were characterized by shallow to deep, Colour of soil pedons varied from 2.5YR to 10 YR 5/6 (Munsell colour chart), soil structure of pedons varied from moderate to medium sub-angular blocky to moderate medium angular blocky. Textural variations in general, varied from sandy loam to clay. The clay content increased with the depth in the majority of the pedons, distribution of silt content did not follow the definite trend in the soils of pedons. The total sand content followed an irregular trend it decreased with increasing depth. The bulk density was increased with the depth. The field capacity, permanent wilting point and available water did not follow the definite trend in the soils of micro watershed. Soils of the micro-watershed were non-saline, low medium in organic carbon and available N, available P2O5, available K2O and available sulphur content medium to high. The free calcium carbonate content increased with increasing depth.
