Ecology and management of forest soils
Forest soils are the foundation of the entire forest ecosystem and complex, long-term interactions between trees, soil animals, and the microbial community shape soils in was that are very distinct from agricultural soils. The composition, structure, and processes in forest soils at any given tim...

Tabla de Contenidos:
- Ecology and Management of Forest Soils; Contents; Preface; Acknowledgments; In Memoriam; PART I INTRODUCTION TO FOREST SOILS; 1 History of Forest Soil Science and Management; OVERVIEW; FOREST SOILS DIFFER INMANYWAYS FROM CULTIVATED SOILS; FOREST SOIL SCIENCE IS AS OLD AS SOIL SCIENCE ITSELF; 2 Global Patterns in Forest Soils; OVERVIEW; SOILS COMMONLY DIFFER AS MUCH WITHIN REGIONS AS AROUND THE GLOBE; MAJOR FOREST TYPES OCCUR ON A VARIETY OF SOILS; TROPICAL FORESTS ARE DIVERSE AND OCCUR ON A DIVERSE RANGE OF SOILS; TROPICAL CLIMATES ARE WARM YEAR ROUND, AND INCLUDE BOTH DRY AND WET REGIONS
- RAINFORESTS HAVE NO PROLONGED DRY SEASONMONSOON FORESTS HAVE SEASONAL PERIODS OF RAIN AND OF DROUGHT; MANY TROPICAL FORESTS ARE DRY; TROPICAL MONTANE FORESTS HAVE MODERATE, UNIFORM CLIMATES; PLANTATION FORESTRY IS EXTENSIVE THROUGHOUT THE TROPICS; SOME TEMPERATE BROADLEAVED FORESTS ARE EVERGREEN; TEMPERATE RAINFORESTS ARE AMONG THE LARGEST FORESTS IN THE WORLD; LOWLAND CONIFEROUS FORESTS ARE MAJOR SOURCES OF TIMBER; TEMPERATE MIXED FORESTS INCLUDE CONIFERS AND HARDWOODS; TEMPERATE MONTANE CONIFER FORESTS ENDURE COLD, SNOWY WINTERS; BOREAL FORESTS SPAN VAST AREAS
- PART II COMPOSITION OF FOREST SOILS3 Soil Formation and Minerals; OVERVIEW; PEDOGENIC PROCESSES OPERATE SIMULTANEOUSLY AT VARYING RATES; EXTERNAL FACTORS GUIDE SOIL FORMATION; PARENT MATERIAL CAN BE MINERAL OR ORGANIC; NONSILICATES ARE IMPORTANT SOIL-FORMING MINERALS; SILICATES ARE THE DOMINANT SOILFORMING MINERALS; CLAY MINERALS ARE SECONDARY ALUMINO-SILICATES; PARENT MATERIALS HAVE BOTH CHEMICAL AND STRUCTURAL FEATURES; CLIMATE IS A MAJOR DRIVER OF MINERAL WEATHERING; BIOLOGY ALSO INFLUENCES WEATHERING; SOILS DEVELOP ACROSS TOPOGRAPHY OVER TIME; BIOLOGY ALSO DRIVES SOIL FORMATION
- VEGETATION AND SOILS DEVELOP TOGETHER, BUT AT DIFFERENT RATESSOIL PROPERTIES INFLUENCE VEGETATION DEVELOPMENT; 4 Soil Organic Matter; OVERVIEW; THE HIGHEST SOIL ORGANIC MATTER MAY BE IN THE CANOPY; FOREST SOIL PROFILES TYPICALLY BEGIN WITH AN O HORIZON; O HORIZONS HAVE A DISTINCTIVE STRUCTURE; MANY O HORIZON CLASSIFICATIONS HAVE BEEN DEVELOPED: ARE THEY USEFUL?; ORGANICMATTERISAVITALPARTOF MINERAL HORIZONS TOO; CHARCOALCANALSOBEIMPORTANT IN FOREST SOILS; SOIL ORGANIC MATTER PERFORMS MANY FUNCTIONS; THE CHEMISTRY OF O HORIZONS GOES BEYOND CARBON
- SOIL ORGANIC MATTER IS MORE THAN THE BALANCE BETWEEN INPUTS AND OUTPUTSWHY DOES ORGANIC MATTER ACCUMULATE IN SOILS?; IS THERE A LIMIT TO HOW MUCH SOIL ORGANIC MATTER CAN ACCUMULATE IN FOREST SOILS?; STUDIES OF LITTER DECOMPOSITION HAVE FASCINATED SCIENTISTS; ORGANIC MATTER ENTERS SOILS FROM ABOVE AND FROM WITHIN; SOIL ORGANIC MATTER SHOWS STRONG PATTERNS ACROSS LANDSCAPES; TROPICAL SOILS HAVE GREATER SOIL ORGANIC MATTER THAN TEMPERATE AND BOREAL SOILS; 5 Water, Pore Space, and Soil Structure; OVERVIEW; MINERALS ARE PLACED IN THREE SIZE CLASSES, COMPRISING SOIL TEXTURE
- TEXTURE INFLUENCES TREE GROWTH
