Abstract:
This experiment investigated soil properties (pH, EC and OC), macronutrient availability (N, P, K S and Ca) and the relationship between soil properties and macronutrient availability. Eight different locations in Bhikiyasain block, Almora district of Uttarakhand, were sampled for soil (0-15 cm depth). N, P, K, S and Ca levels in soil were examined using different methods. Available Nitrogen was analyzed by alkaline KMnO₄ method, available phosphorus by Bray method, available Potassium by Ammonium acetate method, extractable available Sulphur by CaCl₂ method and extractable available Ca by rapid titration method. The soil texture ranged from medium texture to fine texture. The soil pH showed positive and significant correlation with available Phosphorus. The OC and EC showed positive correlation with available K for the entire area of study. After analyzing all nutrient indices, the soils under study were found to be high in extractable N, S and Ca and medium in extractable K and low in P.
