GPS based total 150 surface soil samples (0-15 cm) were collected from each block (30 samples) (namely; Mungaoli, Chanderi, Ishagarh, Ashoknagar and Sadora) of Ashok Nagar district. The samples were prepared and analyzed for different soil properties viz: soil texture (sand silt and clay), pH, EC, soil organic carbon (SOC), Calcium carbonate different forms of potassium (i.e., water soluble, exchangeable, non- exchangeable lattice and total-K) used standard laboratory method. The result showed that range of physico-chemical properties: sand, silt and clay, pH, EC, SOC, CaCO3 in the study region were varied from 36.6-56.7%, 03.9-38.0%, 25.4-42.4%, 7.8-8.6, 0.3-0.6 dSm-1, 2.1–7.2g kg-1, and 0.5 – 3.5 % and similarly value of different forms of potassium i.e. water soluble-K, exchangeable-K, non- exchangeable-K, lattice-K and total-K ranged from 9.4-26.8 mgkg-1, 101.2-205.2 mgkg-1, 300.0-950.0 mgkg-1, 1.0-1.8% and 1.0-1.8% respectively. In general, soil organic carbon and clay content of the soils of study area shows positive relationship with all the forms of potassium, whereas, sand and soil pH show negative relationship. A highly significant and positive relationship was observed between different forms of K, these relationships indicate that there existed equilibrium between these forms of K and depletion of one is instantly replenished by one or more of the other forms of K.
