Week 4: Ion exchange
Ion Exchanges
Cation exchange is the interchanging between a cation in the solution of water around the soil particle, and another cation that is stuck to the clay surface. A soil with a low CEC is much less fertile because it cannot hold on to many nutrients, and they usually contain less clays.
