Scheffer/Schachtschabel Soil Science [PDF ebook] 

The soils are fundamental to our existence, delivering water and nutrients to plants, that feed us. But they are in many ways in danger and their conservation is therefore a most important focus for science, governments and society as a whole. A team of world recognised researchers have prepared this first English edition based on the 16th European edition. * The precursors and the processes of soil development * The physical, biological and chemical properties of soils * Nutrients and Pollutants * The various soil classifications with the main focus on the World Reference Base for Soil Resources (WRB) * The most important soils and soil landscapes of the world * Soil Evaluation Techniques * Basic Principles of Soil Conservation Whoever works with soils needs this book.
