Ecology and Management of Forest Soils
Forest soils are the foundation of the entire forest ecosystem. Not only do soil fungi and bacteria decompose dead plant material, recycling their nutrients, forest soils are also key to protecting water quality. Yet forest soils are fragile, and understanding their unique properties is essential to preserving forest ecology. This revised and updated Third Edition details the distinctive features of forest soils--the factors that set them apart from other types of soils--with an international perspective that includes a discussion of the tropical rainforest soils of Latin America and the boreal forest soils of Siberia. Separate chapters discuss the physical, chemical, and biological aspects of forest soils as well as soil organic matter, roots, and biogeochemistry. The book also touches on the practical management aspects such as nutrition management, site preparation techniques, soils for nursery and seed orchard operation, soil acidity, and techniques for sustaining and improving long-term soil productivity.
