An experiment was conducted in various soil series of Vertisol of Dewas district of Malwa region, Madhya Pradesh to assess potassium fixation capacity and potassium release pattern. The K fixation in different soil series ranged from 72.1-81.9 ppm and the soil series Sarol (S5) recorded the highest mean value of K fixation of 81.9% and Panchdheria(S3) soil series is show the lowest mean value of K fixation of 72.1%.The highest fixation obtained in Sarol (S5)series described to the presence of greater proportion of 2:1 type of clay minerals especially montmorillonites having relatively higher proportion of finer fractions accompanied by greater surface area and large specific adsorption site. The lowest fixation in Panchdheria (S3) described to the relatively low amount of clay in the soil predominant with 1:2 type of clay mineral specially sandy clay loam in texture, therefore having lesser surface area. The cumulative K releasing power of soils are gradually decreased from 1st to 13th extraction. Kamliakheri series released the highest K(119 ppm) and Panchdheria series released the lowest K (84ppm) in 1st exaction of release soil
