After reading this article you will learn about the buffering of soils. Buffering of soils is their resistance against any change in the concentration of hydrogen or other cation in the soil solution. For example, the clay micelle is almost completely saturated with hydrogen ions in strongly acid soils which also contain some in the soil solution. The hydrogen ions [...]
