For determination the status of major soil testing parameters i.e., pH, electrical conductivity, organic carbon and available nitrogen in soils of different land situations, total forty-eight surface (0.0-15.0 cm) soil samples were collected randomly from different sites of Garhwa district, Jharkhand. Based on the analysis of collected soil samples, pH were varied from very strongly acidic (4.80) to moderately alkaline (8.26) in reaction with low electrical conductivity (0.067-0.637 dS m^-1) and organic carbon content varied from very low (1.36 g kg^-1) to very high (13.94 g kg^-1), and available nitrogen status varied from low (144.50 kg ha^-1) to adequate (496.58 kg ha^-1) status with their mean values of 6.41 (pH), 0.23 dS m^-1 (EC) and 6.07 g kg^-1 (OC), 297.88 kg ha^-1 (N), respectively. Among these soils, more soils were fell into the neutral and acidic pH, adequate and medium status of organic carbon and medium and lower category of available nitrogen. Positively significant correlation was found between all the parameter except in pH and OC. As per topographical land situations, in respect of pH, EC, OC and N status in soils trend was found as order upland<lowland<medium land<badi land. From the results I have concluded that if the farmers want to do a profitable crop production should be needed an appropriate management for soil fertility maintain with the supply of decomposed organic manures and balance fertilizers, and also side by side create awareness among the farmers to use these manures and fertilizers in judicious and scientific way. In where soil is acidic condition, especially in upland soil where pH ≤5.5 there should be encouraged to the farmers for lime application along with the sufficient decomposed organic manures and balance fertilizers for optimum yield potential.
