A soil contains {CL}% clay (of the mineral fraction) and {OM}% organic matter (OM). Of the clay {MO}% is montmorillonite, and the rest of the clay is kaolinite (note: %montmorillonite + %kaolinite = 100). Calculate the CEC of this soil. Assume the following CEC’s for each soil component: OM = 250 cmolc/kg montmorillonite = 100 cmolc/kg kaolinite = 8 cmolc/kg Round your answer to 1 decimal place.
