    Clay inherently has more cation exchange sites than sand or silt This is illustrated below where clay is a busy place with lots of cations moving around in and out of the soil solution. Sand, on the other hand, is just a big rock with a few cations on it and not as much opportunity for the cations to move in and out of the exchange sites.
