Ferrolysis

In soil science, ferrolysis refers to the displacement of sorbed cations by Fe (II) ions under reducing conditions as well as the destruction of clay by H ions , which occur when the iron is oxidized again .

In rice soils, which are frequently exposed to changing redox conditions, ferrolysis is said to be the cause of low-clay topsoil, but there are also other opinions about this. In German soils, silicate weathering was rather delayed by temporary water stagnation.
