Six Chemicals That Changed Agriculture

by Robert L Zimdahl, Six Chemicals That Changed Agriculture Book available in PDF, EPUB, Mobi Format. Download Six Chemicals That Changed Agriculture books, Six Chemicals That Changed Agriculture is a scientific look at how the chemicals used in today's food production were developed, evaluated, and came to be in wide-spread use. From fertilizers to pest management, antibiotics to DNA, chemicals have transformed the way our food is grown, protected, and processed. Agriculture is the world's most important environment interaction, the essential human activity, and an increasingly controversial activity because of its use and presumed misuse of chemistry. The major characteristics of US agriculture for at least the last six decades have been rising productivity, declining number of mid-size farms, increasing farm size, an increasing percentage of farm production on fewer, large farms, increasing dependence of chemical technology and more developmental research being done by the agricultural chemical industry rather than by independent land-grant universities. Another equally important feature of modern agriculture is wide-spread suspicion of its technology by the public. The book will recount examples of this suspicion related to specific chemicals and present the essence of the suspicion and its results. Offers an historical analysis of the discovery and development some aspects of the chemistry of modern agriculture Addresses the advantages, disadvantages, desirable and undesirable results of the use of each of the chosen chemicals and compares and contrasts the real and frequently assumed problems of their use Provides valuable insights into the history and application of these focused chemicals, enabling readers to apply the lessons to new agricultural chemical developments

Agriculture S Ethical Horizon

by Robert L. Zimdahl, Agriculture S Ethical Horizon Book available in PDF, EPUB, Mobi Format. Download Agriculture S Ethical Horizon books, What are the goals of agricultural science? What should the goals of agricultural science be? How do and how should the practitioners of agriculture address complex ethical questions? These questions are explored in this monumental book so that those in agriculture will begin an open dialoge on the ethics of agriculture. Discussion of foundational values, of why we practice agriculture as we do, should become a central, rather than peripheral, part of agricultural practice and education. If agricultural scientists do not venture forth to understand and shape the ethical base of the future, it will be imposed by others. Largely autobiographical, this book covers topics such as scientific truth and myth, what agricultural research should be done, an introduction to ethics, moral confidence in agriculture, the relevance of ethics to agriculture, sustainability, and biotechnology. * Written by an expert who has been engaged in agricultural education and research for over 35 years * Content is easily understandable by non-philosophers * The concepts of scientific truth and myth are contrasted and compared * Chapter sidebars highlight important concepts and can be used to engage students in further discussion * Companion website will accompany the book with further teaching aids and a discussion board

Agricultural Ethics An Invitation

by Robert L. Zimdahl, Agricultural Ethics An Invitation Book available in PDF, EPUB, Mobi Format. Download Agricultural Ethics An Invitation books, I write because I am concerned that I and my agricultural colleagues have avoided addressing the moral dimension of the environmental and social problems we have contributed to. I hope for an exchange of ideas about agriculture's moral dilemmas. I encourage my readers to engage in a collective conversation about the dilemmas and avoid remaining in what Merton calls "the collective arrogance and despair of his own herd." If those engaged in agriculture continue to ignore and fail to realize our common difficulties they will be addressed and resolved by societal pressure and political action, which may not yield the resolution we favor. The book's goal is not to resolve the moral dilemmas raised. It is to raise them and encourage thought and discussion. It will ask but not answer why nearly all involved in agriculture have not addressed the moral concerns voiced by the general public. The agricultural enterprise is committed to the benefits and future success of the present, very productive, chemical, capital, and energy intensive system, which is, in the minds of many, not sustainable. The internal justification invokes the moral claim that they feed the world's population. The question remains whether or not the prevailing moral justification of feeding the world is adequate given all the issues modern, developed country agriculture faces: pesticides in soil, water, and food, cruelty to animals, Biotech/GMO's, corporate agriculture, pollution by animal factory waste, exploitation of and cruelty to migrant labor.

Fundamentals Of Weed Science

by Robert L Zimdahl, Fundamentals Of Weed Science Book available in PDF, EPUB, Mobi Format. Download Fundamentals Of Weed Science books, This book addresses herbicides and their use as an important aspect of modern weed management and strives to place them in an ecological framework. Many weed scientists believe agriculture is a continuing struggle with weeds--without good weed control, good and profitable agriculture is impossible. Each agricultural discipline sees itself as central to agriculture's success and continued progress, and weed science is no exception. While not denying the importance of weed management to successful agriculture, this book places it in a larger ecological context. The roles of culture, economics, and politics in weed management are also discussed, enabling scientists and students to understand the larger effects on society. Information on New herbicides included, along with the old herbicides that are important for understanding the history New section on weed resistance to herbicides and genetic engineering New information on invasive plants Expanded chapters on Biological Control, Pesticide Legislation and Regulation, Weed Management Systems, and more Instructor resources can be found at http://textbooks.elsevier.com/web/Login.aspx, and it is password protected.

A History Of Weed Science In The United States

by Robert L Zimdahl, A History Of Weed Science In The United States Book available in PDF, EPUB, Mobi Format. Download A History Of Weed Science In The United States books, It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed science’s development. The first analytical history of weed science to be written Compares the development of weed science, entomology and plant pathology Identifies the primary founders of weed science and describes their role
