Buch. Zustand: Neu. Neuware - Explore the benefits of and necessity for sustainable agriculture!Here is an easy-to-read, practical introduction to sustainable agriculture: what it means and why it is needed. It is the first book to synthesize the goals of sustainable agriculture into eight comprehensive steps. The Next Green Revolution presents a convincing critique of our current agricultural system and an introduction to an alternative system which gives more consideration to future generations. Interwoven through the book are Dr. Horne's reflections on social justice, quality of life, and how farmers and rural communities are inextricably linked.The Next Green Revolution draws on the unique perspective of Dr. James E. Horne, President of a leading nonprofit agriculture organization, the Kerr Center for Sustainable Agriculture. It is inspired by his experience as a traditional agriculturalist and educator coming to grips with the failings of the conventional system and searching for an alternative. Writing in the first person, he describes growing up in a sharecropper family in Oklahoma, running his own ranch, and consulting with farmers as an agricultural economist. He shares what he learned as the Kerr Center experimented with new 'sustainable' approaches to old problems on the Center's ranch/farm, and his experiences working with the USDA's Sustainable Agriculture Research and Education Program. With The Next Green Revolution, you will explore: - the major problems of contemporary industrial agriculture - definitions of sustainable agriculture - the historical roots of sustainable agriculture - the politics of sustainable agriculture - sustainable agriculture practices - changes needed to encourage a sustainable agriculture and the eight steps to sustainable agriculture, which address: - soil health and erosion - water quality and use - organic waste management - crop and livestock adaptation - biodiversity - environmentally benign pest management - energy use - farm diversification - profitability The Next Green Revolution is a well-researched introduction to the field, written with a minimum of jargon.…

Taschenbuch. Zustand: Neu. Neuware - Discover environmentally safe ways to control weeds and pests!Until now farmers have had to choose between using expensive herbicides and fertilizers, which pollute the water table, or watching crop yields drop. All too often, crop yields dropped anyway, despite intensive farming. Allelopathy in Agroecosystems offers fresh hope. It provides an in-depth understanding of allelopathy-the mysterious, complex biochemical interactions among plants and microbes. This little-understood phenomenon plays a large role in agriculture, for good or ill. It can lead to changes in nutrient dynamics, vegetation structure, and species diversity. This comprehensive treatise is the first compendium devoted to explaining and exploring these chemical interactions in agricultural crop systems. Allelopathy in Agroecosystems explains how these interactions can make soil 'sick,' especially in intensively cropped areas. This leads to less growth and lower yield. On the other hand, it has great potential as an environmentally safe method of weed and pest management. The fascinating original research presented here will help you understand the complexities of this invisible yet potent force in agriculture.Allelopathy in Agroecosystems examines this interaction as it affects the most important concerns of farmers and agronomists, including: - beneficial interactions between crops - weed control using crop residues - crop rotation - natural herbicides - genetic engineering - soil rhizosphere bacteria - improving pastures - forest/crop interactions - sustainable management of agroecosystems - new directions for research International in scope, Allelopathy in Agroecosystems offers an abundance of scientific data on this revolutionary new concept. It offers incalculable potential for rescuing farmed-out land, increasing crop yields, and cutting back on expensive soil additives. Every agronomist, environmental scientist, policymaker, agricultural librarian, and advocate of sustainable farming needs this book.…

Buch. Zustand: Neu. Neuware - Why do women live longer than men Does ownership of paired X chromosomes confer more prolonged survival on females, or is the gender difference in life-expectancy a cumulative consequence of differing life experiences for women and men The areas of gender differences in aging, functional capacity, and the response to physical activity have often been the basis for speculation rather than informed judgment.Gender, Physical Activity, and Aging draws upon the sound knowledge base of leading investigators to provide objective, evidence-based evaluations of particular facets of the aging process. Focusing on gender differences, it examines the rate of aging, loss of functional capacity, disability, and the quality of life among the elderly and presents evidence of potential modification through physical activity and lifestyle.…

Buch. Zustand: Neu. Neuware - A state-of-the-art review of original research, this book includes discussions of intramolecular photoadditoin of nucleophiles, electrophiles, and radical species to the activated aromatic ring; new methods for regio-, anantio-, and diastereoselective photooxygenations involving singlet oxygen mechanisms; and applications of microreactors for photochemical synthesis of large-ring compounds, photochemical rearrangement, photocycloaddition, and chiral photochemical synthesis. It covers the role of layered inorganic solids in the construction, characterization, and analysis of supramolecular assemblies of metal ions, molecules, metal complexes, and proteins, and more.…
