This is a rigorous introduction to soil chemistry for non-specialist undergraduates and graduate researchers. The author describes soil minerals and organic matter in soils and the soil solution, and provides in-depth coverage of important chemical processes - these include 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 of varying difficulty are co-ordinated with the text, and an appendix of SI units summarizes their use in soil chemistry.
