Vermiculite is a micabased clay similar to illite but the crystals of are held together more loosely by hydrated magnesium and will swell not much does has very high CEC. It is of use in calculating the amount lime needed to neutralise an acid soil. Organisms colonise and break down organic materials making available nutrients upon which other plants animals can live. Buffering occurs by cation exchange and neutralisation. Soil piping is a particular form of erosion that occurs below the surface
