Cation Exchange Capacity (CEC)

Common CEC ranges in New York Sandy soils low in organic matter have a very low CEC (less than 3 cmol c/kg) while heavier clay soils or soils high in organic matter generally have a much higher CEC (greater than 20 cmol c/kg). Table 1 gives an estimate of a typical CEC of soils of each of the five soil management groups in New York (see
