Abstract :
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 (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 (
