An investigation was carried out to study the distribution of available macronutrients (N, P, K and S) and their relationship with some physico-chemical properties of soil of different blocks of district Udham Singh Nagar (Uttarakhand).The soils of the district were found sufficient in Phosphorus, Potassium and Sulphur but low in available Nitrogen content. In general the macronutrients were correlated significantly and negatively with pH and positively with organic carbon of the soil. The values of the organic carbon, Alkaline KMnO4 extractable N, Olsen’s P and neutral normal Ammonium Acetate extractable K in the Udham Singh Nagar district ranged between 0.13-1.64 per cent, 125.44-338.68 kg N ha-1, 7.34-76.70 kg P2O5 ha-1 and 66.08-271.04 kg K2O ha-1, respectively. From the above findings it may be concluded that the soils of Udham Singh Nagar district are low in nitrogen, sufficient in phosphorus & in potassium, Except Sitarganj, Jaspur and Bazpur samples were low in potassium, sufficient in sulphur except Rudrapur. These findings from present study can successfully be utilized for the larger parts of Tarai region of Uttarakhand as effective guide for efficient and balanced fertilizer recommendations.
