An extensive study of exchange properties of surface and subsurface soil samples of the main campus of Kerala Agricultural University, Vellanikkara, covering a total of 914 samples was conducted. The 0.1 M BaCl2 extractable exchangeable ions, CEC and the relative factor(s) in terms of ionic ratios of monovalent (K+ and Na+) ions to the divalent and/or trivalent ions, computed based on ratio law were subjected to regression analysis in an attempt to predict the contents of the exchangeable ions. In the case of exchangeable K and Na, the ratios [K/ (Ca + Mg + Mn + Fe)1/ 2 + (AI)1/3] and [Na/ (Ca + Mg + Mn + Fe)1/ 2 + (AI)1/3], respectively, could predict 60 to 70
