Q/I parameters of potassium were studied on fourteen composite soil samples (0-30) collected from sheat fields , fallow and uncultivated ateas having 76 to 600 ppm ammonium acetate -K. Soil textures varied from sandy loam to clay loam. Salinity problem was not observed in theses soils. Soil pH and SOM content renged from 7.7 to 8.2 and 0.3 to 1.3 respectively . The correlation coefficient (r) between soil properties such as pH, organic matter, Calcium carbonate, EC, and silt content with quantity and Intensity parameters which govern the dynamics and avaliability of potassium were½ not related .The amount of ARok ranged from 0.3 to 7.6 with a mean value of 3.38 (mol/l) la.The value of PBCk ranged from 31.1 to 90.86 with a mean value of 44(Cmollkg) (mol/l) ½• The labil potassium (KL) ranged from 0.008 to 0.694 (Cmol/kg) ½ with a mean value of 0.172 and the value of K-potential ranged from 2.11 to 3.25 with a mean value of 2.63 The study indicated that there is no significant correlation between PBCk and clay content .The correlation coefficient of ARok and KL with NH4 OAc-k were significant (r=0633, 0/59)the correlation coefficient between k-potential, pM and NH4 OAC-k were negatively significant (r-0.665, 0.628) Mineralogical studies showed that dominant clay Minerald were chlorite jute and vermiculite respectivly.
