Abstract: The present investigation entitled “potassium fractionation of mandarin growing soil of Katol tahsil of Nagpur” was conducted on farmer’s field at Katoltahsil, Dist. Nagpur during Kharif 2017-18. Seven locations viz., Niravha, Iratni, Botesari, Silli, Savangi, Salaidhaba and Baravha were selected to determine the different fractions of soil potassium and its correlation with soil properties. 35 surface soil samples (5 soil samples each from one location) were taken from 0-20 cm depth over the field of Nagpur mandarin orchards. The results revealed that the contribution of different K fractions at surface level was in order of lattice K > non exchangeable K > exchangeable K > water soluble K. Available K bears highly significant and positive correlation with water soluble K (r=0.813**) and exchangeable K (r=0.998**). Lattice K showed negatively significant correlation with available K (r= -0.377*), water soluble K (r= -0.422*), exchangeable K (r= -364*) and non-exchangeable K (r= -0.524*). Water soluble K shows highly positive and significant correlation with exchangeable K (r= 0.998**) and it shows negatively significant correlation with lattice K (r= -0.422*).
