Oxisol structure


This is a 100x magnification of a thin section of an Oxisol from Thailand.The well-structured aggregates are composed of mixture of kaolinite and Fe oxide (hematite). These stable aggregates are responsible for high infiltration and permeability, and this make many Oxisols resistant to runoff and erosion.
