Upload NowAfter 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 […]
Phosphate Retention and Fixation in Soil
Article shared by :
After reading this article you will learn about phosphate retention and fixation in soil. Kaolinite has a strong affinity for phosphate anions. Phosphate anions can be attracted to soil constituent with the force strong enough to make them insoluble and difficulty available to plant roots. Tisdale and Nelson (1975) have differentiated phosphate retention from phosphate […]
