Book excerpt: Excerpt from Research Progress and Needs Conservation Tillage An in-depth understanding of the influence of tillage and residue manage ment systems on the physical, chemical, and biological components of the plant-soil environment will be an essential component in optimizing conserva tion production systems with crop yield and quality. Unfortunately, because tillage itself is a physical manipulation of the soil, much tillage research has stressed the effects on the physical characteristics of soil; only minor emphasis has been placed upon biological considerations. Tillage alone can have dramatic effects upon biological equilibria and microbial populations in soil (mccalla, Reductions in crop yield, associated with conservation production systems, have emphasized the need for a complete understanding of the biological changes in the soil environment. Research to determine the biological effects of minimum tillage and residue management will be multidisciplinary because of the necessity of studying the microbiology, biochemistry, chemistry, and physics of the plant-soil environ 'ment, as well as the physiology and disease and insect-vulnerability of the crop itself. An important component in the study of conservation production systems should be the characterization of the microbiology of the soil This aspect should not only involve the correlation of counts of soil fungi, actinomycetes, and bacteria with the conservation production systems. It also should include the effects of tillage and residue incorporation upon microorganisms that are responsible for such agronomically and environmentally important transforma tions as nitrification and denitrification. In specifically studying theeffects of residue management on production of phytotoxic compounds, the water - soluble and gaseous phytotoxic compounds will have to be identified. In the case where phytotoxic compounds are being produced by microorganisms, the microorganisms responsible for their production will have to be identified. Research relating to production of specific phytotoxins will involve laboratory. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Have agricultural management efforts begun in the desperation of the Dust Bowl brought us to where we need to be tomorrow? Questions about the environmental footprint of farming make this book required reading. Approximately 62% of the total U.S. land area is used for agriculture, and this land also provides critical ecosystem functions. Authors from each region of the continental United States describe the progress of soil and water conservation to date and visualize how agricultural production practices must change in future years to address the newest challenges.

This book was released on 1991-02-01 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest is growing in sustainable agriculture, which involves the use of productive and profitable farming practices that take advantage of natural biological processes to conserve resources, reduce inputs, protect the environment, and enhance public health. Continuing research is helping to demonstrate the ways that many factorsâ€"economics, biology, policy, and traditionâ€"interact in sustainable agriculture systems. This book contains the proceedings of a workshop on the findings of a broad range of research projects funded by the U.S. Department of Agriculture. The areas of study, such as integrated pest management, alternative cropping and tillage systems, and comparisons with more conventional approaches, are essential to developing and adopting profitable and sustainable farming systems.

This book was released on 2010-07-25 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.
