The study entitled “Physicochemical studies of soil on the growth of Sal forest in Hazaribag” was carried out in Hazaribag district, Jharkhand, India. This is the natural forest, dominated by Sal trees which had large economic value, and thus, a scientific forest management system was necessary for this forest. The paper describes the different basic factors which support the proliferous growth of Sal dominated forest found in these areas. The soil sampling was done using a quadrate method based on the principle of systematic sampling. Ten samples were collected from the Ichak and Bishnugarh Sal forest of Hazaribag for the study of soil properties. The soil samples from eight quadrates were taken for the determination of Soil texture, MC, WHC, OC, OM, pH, N, P, Na, K, and Ca. The soil pH is slightly acidic which was found to be in the range of 6.05-6.40. Moisture content, water-holding capacity, organic carbon, organic matter, total nitrogen of soil samples were found to be in the range of 7.20%-13.20%, 55.90%- 77.70%, 1.32%-2.40%, 2.65%-4.05%, 0.17%-0.34%, respectively. P, Na, K in mg/L was found to be in the range of 0.54 mg/L-0.92 mg/L, 2.5 mg/L-5.3 mg/L, 8.7 mg/L-15.14 mg/L and Ca in meq/100 g was found to be 6.3 meq/100 g-7.4 meq/100 g respectively.
