Soil and Water Science
Soil and water science defined as the controlling soil water content at an optimal state for all given purposes, including environmental needs. An optimal state is often a compromise between competing uses and needs to account for long term sustainability of the soil water system. Adsorption is the process by which constituents attached to the surface of the soil. Adsorption processes are governed by the organic and inorganic components properties of the soil. Substances which can be adsorbed by soil particles include soil constituents, plant nutrients, surfactants, antibiotics and toxic environmental pollutants present in soil solutions.
