In this article we will discuss about:- 1. Introduction to Cation Exchange 2. Cation Exchange Capacity (C.E.C.) of Soils 3. Factors Affecting Cation Exchange Capacity 4. Importance. Introduction to Cation Exchange: Cation exchange is a reversible process in which the cations are exchanged or interchanged between the solid and liquid phases or between the solid and solid phases when they [...]
After reading this article you will learn about the importance of cation exchange in plant nutrition. Cation exchange is an important reaction in soil fertility, in correcting soil acidity and basicity, in altering soil physical properties, and as a mechanism in purifying or altering percolating waters. Plant roots, when they come in contact with colloidal particles, adsorb exchangeable cations directly [...]
