Soils underpin human survival and environmental quality; however, they are infinitely variable. The clays present in soil dictate the ability of the soil to support and sustain the growth of plants, retain organic matter, and host useful microbes. This book describes the origin of soil clays, occurrences, and influences their mode of formation has on soil. It provides a new understanding of the nature of clay minerals, clay surface chemistry, and clay-organic-nutrient-water interactions relevant to soil function and environmental outcomes. The book aims to improve predictions of important properties of soils through understanding their highly reactive clay minerals in soils worldwide.
