The present investigation is a part of trail that was continued during 2009 to 2013 and the GPS based survey work of the tribal district (Shahdol) was under taken during the year 2011-2012. From the whole district sixty eight villages have been covered and 408 soil samples were drawn at the depth of 0-20 cm. Six soil samples were taken from each village on the basis of land holding having low (<1 ha), medium (1-3 ha) and high (> 3 ha) farmer categories along with GPS data and only two soil samples were taken from each category. These soil samples were analyzed for different parameters viz pH, EC, O.C., available N, P, K, S and micronutrients like Zn, Cu, Fe and Mn. Spatial variability of soil chemical properties viz. pH, EC, organic carbon, soil available macronutrients (N, P,K) and micronutrients (Fe, Mn, Cu, Zn) were quantified through descriptive statistical analysis and the respective surface maps were prepared through ordinary kriging. The soils of the area are characterized by neutral to alkaline in pH and low to high in organic carbon content. The soil available nitrogen content were ranged from 109-476 kg ha-1, available soil phosphorus were ranged from 5.9-53.2 kg ha-1, available potassium were ranged from 102-827 kg ha-1 and available sulphur were obtained from 3.6 to 46.3 mg kg-1. While values of micronutrient were reported from 0.10 to 4.73 mg kg-1 with Zn, 0.21 to 11.1 mg kg-1 with Cu, 4.5 to 84.8 mg kg-1 with Fe and 2.0 to 74.1 mg kg-1 with Mn.
