Soils and Soil Fertility
This successful textbook is intended as an introduction to soils for students in agriculture and related sciences. Broad in scope, the book includes chapters on basic topics such as soil chemistry, organic matter, mineralogy, water management, as well as on more specialized areas such as urban and rural land use, artificial soils for greenhouses, and turf grass. Environmental concerns are now addressed in an individual chapter. Background information on these topics is presented where necessary to help beginning students. In addition to students of agronomy, special effort has been taken to make the book useful for those with interests in horticulture, forestry, and engineering and recreational uses of soils. The breadth of coverage allows this book to serve as background for more advanced courses in soils and as a general review of soil sciences.
Integrated Resource Management
Written to help bring agriculture's "Green Revolution" to the third world, Integrated Resource Management includes overviews of current agricultural production systems and their alternatives, demographics on mortality and population growth, soils, erosion, water availability, sustainable integrated agroforestry systems and behavioral adaptations. - Explains why a quality environment is essential for future agricultural and economic development Demonstrates that integrated resource management leads to sustainable and productive agriculture for development - Shows that certain agroforestry techniques conserve soil, water, energy, and biological resources and at the same time increase food and fuel supplies - Addresses the need for interdisciplinary and multidisciplinary research and training to implement sound resource management policies and programs
The Story of N
In The Story of N, Hugh S. Gorman analyzes the notion of sustainability from a fresh perspective—the integration of human activities with the biogeochemical cycling of nitrogen—and provides a supportive alternative to studying sustainability through the lens of climate change and the cycling of carbon. It is the first book to examine the social processes by which industrial societies learned to bypass a fundamental ecological limit and, later, began addressing the resulting concerns by establishing limits of their own The book is organized into three parts. Part I, “The Knowledge of Nature,” explores the emergence of the nitrogen cycle before humans arrived on the scene and the chang...
Geoecology: An Evolutionary Approach
Animals, plants and soils interact with one another, with the terrestrial spheres, and with the rest of the Cosmos. On land, this rich interaction creates landscape systems or geoecosystems. Geoecology investigates the structure and function of geoecosystems, their components and their environment. The author develops a simple dynamic systems model, the `brash' equation, to form the conceptual framework for the book suggesting an `ecological' and `evolutionary' approach. Exploring internal of `ecological' interactions between geoecosystems and their near-surface environments - the atmosphere, hydrosphere, toposhere, and lithosphere - and external influences, both geological and cosmic, Geoecology presents geoecosystems as dynamic entities constantly responding to changes within themselves and their surroundings. An `evolutionary' view emerges of geoecological systems, and the animals, plants, and soils comprising them, providing a new way of thinking for the whole environmental complex and the rich web of interdependencies contained therein.
The Bio-Integrated Farm
The Bio-Integrated Farm is a twenty-first-century manual for managing nature's resources. This groundbreaking book brings "system farming" and permaculture to a whole new level. Author Shawn Jadrnicek presents new insights into permaculture, moving beyond the philosophical foundation to practical advanced designs based on a functional analysis. Holding his designs to a higher standard, Jadrnicek's components serve at least seven functions (classical permaculture theory only seeks at least two functions). With every additional function a component performs, the design becomes more advanced and saves more energy. A bio-integrated greenhouse, for example, doesn't just extend the season for grow...
The Hidden Curriculum—Faculty-Made Tests in Science
This resource manual for college-level science instructors reevaluates the role of testing in their curricula and describes innovative techniques pioneered by other teachers. part I examines the effects of the following on lower-division courses: changes in exam content, format, and environment; revisions in grading practices; student response; colleague reaction' the sharing of new practices with other interested professionals, and more. The book includes a comprehensive introduction, faculty-composed narratives, commentaries by well-known science educators, and a visual index to 100 more refined innovations.
The Literature of Soil Science
A collection of 14 discussions of the past and present literature about soil science. The topics include a historical survey, bibliometrics, introduction into developing countries, societies and their publishing influence, information systems, core monographs, primary journals, maps, and other aspec
Agriculture and Food in Crisis
The failures of “free-market” capitalism are perhaps nowhere more evident than in the production and distribution of food. Although modern human societies have attained unprecedented levels of wealth, a significant amount of the world’s population continues to suffer from hunger or food insecurity on a daily basis. In Agriculture and Food in Crisis, Fred Magdoff and Brian Tokar have assembled an exceptional collection of scholars from around the world to explore this frightening long-term trend in food production. While approaching the issue from many angles, the contributors to this volume share a focus on investigating how agricultural production is shaped by a system that is oriente...
