Abstract
An investigation was conducted to analyse the distribution of available plant nutrients and to examine the relationships between soil properties and available nutrient status in soil profiles of Eastern India. Three soil profiles were exposed under three different topographic positions. In all the pedons, soil reaction (pH) was increasing and EC was very nominal because there is no accumulation of dissolved salts in the soil pedons. The status of available N was decreasing with soil depth and phosphorus (P) was increased with depth of soil, Organic carbon (OC) was unevenly distributed with the depth of soil, sulphur was also unevenly distributed with depth of soil which is comparable with the (OC). There is similar trend between pH and P.
