The soil adsorption complex acts as a primary reservoir of nutrients, preventing their leaching and providing plants with nutritional elements through the ion exchange mechanism. The article reveals the principles of adsorption, the role of colloidal particles, and the equilibrium dynamics between the solid phase of the soil and the soil solution.
