Already renowned as a user–friendly beginners guide to soil science, Soil Science Simplified, 6th Edition is an updated version of the beloved textbook that includes even more thorough applications of soil science to interdisciplinary fields. It includes the most recent research concerning uses of soil in municipal, engineering, and other areas, conversion agriculture covering no–till, hoe–till, and the methodology of cover crops, crop rotations, N contribution, and worldwide trends in conversion agriculture. The experienced authors have fully revised and updated the fundamental chapters on physical, chemical, and biological properties to create an ideal introductory text. INDICE: 1.
