This book is a tool for understanding our greatest natural resource. The ground we stand on, the earth we mine, the land that produces food, fiber, and shelter, and yet few of us can even define soil, let alone explain how it works, what it does, or how it changes. This book contains the soil information, root growth and agricultural management, nitrate leaching management, podzols, paramos soils, water repellant soils, rare earth elements, and much more…. presents hundreds of entries on tillage, irrigation, erosion control, minerals, ground water, and soil degradation… outlines the agricultural, environmental, industrial, and cultural components that affect soil productivity… offers quick access to peer-reviewed articles on all branches of soil science–from mineralogy and physics to soil management, restoration and global warming… and assesses the physical and hydrological properties of soil in natural and agricultural ecosystems.
