  Cation Exchange

  However, climate exerts a natural control or limit as to the amount of soil organic matter that can be achieved and sustained. Cation exchange capacity (CEC) The CEC of a soil depends upon the amount and type of soil colloids present. The clay content, the type of clay minerals present, and the organic matter content determine a soil''s CEC.

  Clay minerals: Ion exchange | SpringerLink

  Ion exchange is the substitution of one ion for another on the surface or in the interstices of a crystal. It does not affect crystal structure. Ion exchange in clay minerals occurs because clay minerals can sorb ions and, to a lesser extent, anions from solution. However, when exposed to a different solution, some of these sorbed ions are ...
