cation exchange

n.
A chemical process in which cations are exchanged equally between a solid, such as zeolite, and a solution, such as water. The process is often used to soften water.

Soil structural changes and therefore cation exchange equilibria in undisturbed soils are likely to differ where the lack of mechanical force may prevent separation of clay platelets to the same extent.
These parameters may be determined directly using laboratory methods (by measuring soil water content over a range of matric pressure heads) or indirectly by relating water retention functions (pedo-transfer functions) to some easily measured soil physico-chemical parameters such as soil texture, oven-dry bulk density, organic carbon, cation exchange capacity, etc.
