Overview


A rigorous, comprehensive introduction to soil chemistry, this text is aimed at students and researchers who are not soil chemists. The author describes soil minerals and organic matter in soils and the soil solution, and provides in-depth coverage of important chemical processes, including solubility reactions, oxidation-reduction phenomena, adsorption, and ion exchange. The three final chapters present detailed applications to soil-plant relationships, fertilizer reactions in soils, acidity, salinity, mineral weathering, and soil management. Over 200 problems at varying levels of difficulty are coordinated with the text, and an appendix on SI units summarizes their use in soil chemistry.
