Article shared by :
After reading this article you will learn about the cation exchange capacity (C.E.C) of soil and factors affecting it. The total number of cation adsorption sites per unit weight of soils is called the cation exchange capacity of soils. The cation exchange capacity of the soil may also be defined as the total number of […]
Cation and Anion Exchange in Soils
Article shared by :
After reading this article you will learn about the cation and anion exchange in soils. Cation Exchange in Soils: Cations surrounding the soil colloidal complex i.e. clay and humic micelle are called exchangeable cations because they can be reversibly replaced equivalently by other cations. For example when ammonium chloride is applied to the soil, then […]
