Soil-land form relationship was studied for Ayyammanahalli village by the interpretation of satellite and Google earth imagery. Sampling areas in transect were marked along the slopes based on the tonal variation. The selected transect areas were marked for profile study, five representative pedons were exposed on five different physiography, like Upland summit, Upland lower sector, Upland upper sector, shoulder of upland and lowland. The study area represents semi arid tropical climate. It has vast areas of upland and considerable area of lowland. Majority of the upland is under field crops. Upland has very gentle to gentle slope.Keywords

Study was undertaken in Western Ghats and Coastal area in Karnataka state, India with the aim of evaluating the fertility status of soils using nutrient index approach, mainly for primary nutrients. Based on fertility ratings, pH of soils was strongly acidic to moderately acidic. Electrical conductivity was normal (<1.0 dS m-1). Soil organic carbon was medium to high. Primary nutrient status i.e., N, P and K were low in >60 % samples. Whereas, >80 % of samples were low in exchangeable Ca, Mg and available S content. Among the micronutrients Cu and B were found to be low in >70% of samples, whereas Fe, Mn and Zn were adequate in >85 % of samples. Nutrient index value for major nutrients (available N, available P and available K) was found to be low (<1.67 range).Keywords
