Article shared by :
After reading this article you will learn about the cation and anion exchange in soil. Cation Exchange: In a near neutral soil, calcium remains adsorbed on colloidal particle. Hydrogen ion (H+ ) generated as organic and mineral acids formed due to decomposition of organic matter. In colloid, hydrogen ion is adsorbed more strongly than is […]
