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 [...]
This article provides a short note on calcareous soils. Zonal soils of arid regions usually contain sufficient amount of lime (CaCO3) at some horizons of the soil profile. When the zone of lime accumulation coincides with the depth of high root concentration, it may be an important factor in plant nutrition. Many soils are formed from limestone or marl parent [...]
