Abstract: One hundred fifty GPS based surface soil sample of mustard growing fields were analysed for different physico-chemical properties and different forms of potassium (i.e. water soluble, exchangeable, non exchangeable, mineral and total. Soils were neutral to slightly alkaline in nature with having normal electrical conductivity and calcium carbonate content. Organic carbon was found in the range of 0.180 to 0.640 per cent with average value of 0.441 percent. The amount of water soluble, exchangeable and non-exchangeable-K in different villages of Gwalior district; ranged from 7.2 – 26.4, 115.2 – 330.2 and 290.4 – 965.4 mg kg-1 with the mean value of 15.1,230.5 and 548.4 mg kg-1 respectively. These forms contributed 0.102, 1.55 and 3.70% towards total-K. Whereas, Lattice and total-K found in the range of1.072-1.729 and 1.127-1.859% with the mean value of 1.403 and 1.482% respectively. Lattice – K contributed maximum (94.67%) towards total-K. organic carbon and clay content of the soils of mustard growing fields shows positive relationship with all the forms of potassium, whereas, sand and soil pH show negative relationship. A highly significantly and positively relationship were observed between different forms of K.
