Available in PDF, EPUB and Kindle. Book excerpt: The development of chemicals to selectively control the growth of weeds has been a fascinating success story which has unfolded largely during the last four decades. The dramatic growth of herbicide research that followed the wartime discoveries of the auxin-type herbicides (phenoxyalkanoic acids) resulted in a whole range of compounds and mixtures which are used to eliminate broad-or narrow-leaved weeds from agricultural, horticul tural, or forestry crops. Today, the safe use of this armament of compounds requires our understanding of their mode of action, metabolism, and environmental persistence. The most recently developed herbicides are highly effective inhibitors of specific enzyme systems, and formulation may be an important factor determining their efficient delivery at specific target sites. In this book, the major target sites of herbicide action are discussed in Chapters 1-5, with particular reference to photosynthesis; amino acid, lipid, and carotenoid synthesis; and other primary target sites. The effects of synergists or antagonists as modifiers of herbicide action are described in Chapter 6. The importance of efficient target site delivery as a fundamental factor in herbicide activity and selectivity is generally recognized. Delivery of a potentially lethal dose of active ingredient may depend on a whole range of factors including the efficiency of application, retention, absorption, translocation, immobilization, and detoxification. These aspects are con sidered in the remaining chapters, with particular reference to the pathways and mechanisms involved in the uptake, translocation, and metabolism of soil-and foliage-applied herbicides.

Available in PDF, EPUB and Kindle. Book excerpt: The world population in 1930 was 2 billion. It reached 3 billion in 1960, stands at 4. 6 billion today, and is expected to reach 6 billion by the end of the century. The food and fiber needs of such a rapidly increasing population are enormous. One of the most basic resources, perhaps the most basic of all, for meeting those needs is the Soil. There is an urgent need to improve and protect this resource on which the future of mankind directly depends. We must not only learn how to use the soil to furnish our immediate needs, but also ensure that the ability of the soil to sustain food production in the future is unimpaired. This is indeed a mammoth task; a 1977 United Nations survey reported that almost one-fifth of the world's cropland is now being steadily degraded. The diversity of soil makes it necessary for research to be conducted in many locations. There are basic principles, however, that are universal. This series, Advances in Soil Science, presents clear and concise reviews in all areas of soil science for everyone interested in this basic resource and man's influence on it. The purpose of series is to provide a forum for leading scientists to analyze and summarize the available scientific information on a subject, assessing its importance and identifying additional research needs. But most importantly, the contributors will develop principles that have practical applications to both developing and developed agricultures.

Book excerpt: This work provides the fundamental information necessary for the development of weed management strategies for all the major US crops using concepts that can be applied worldwide. Weed management systems are provided for cotton, peanut, soybean, wheat, barley, oat, sorghum, rice, fruits, nut crops, and more. The dynamics involved in creating the best management approaches for specific types of crops are explained.

This book was released on 1971 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of microorganisms with specific degradative capacities into the soil was shown to be a possible means of ridding the soil of contaminating chemicals. An investigation of the interactions of soil microorganisms and several groups of herbicidal compounds, primarily chlorinated derivatives, was made. In pure culture and in soils the addition of 2,3,5,6-tetrachloroterephthalate (DCPA) had little effect upon bacterial growth, and several microorganisms appeared to use the herbicide as a carbon source. The encouragement of the soil microflora by the addition of nutrient broths resulted in a reduction of toxicity to plants of a number of herbicides. Isopropyl N-phenylcarbamate (IPC) degrading organisms, when added to soil, accelerated the degradation of IPC and related compounds. A membrane 'biologicalilter' device for reducing waterborne biodegradable pollutants was also demonstrated using these organisms.
Download or read book Soil Ecology written by Ken Killham and published by Cambridge University Press. This book was released on 1994-03-03 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil Ecology is an exciting textbook for all those concerned with the environment. The author meets the increasing challenge faced by environmental scientists, ecologists, agriculturalists and biotechnologists for an integrated approach to soil ecology. Intellectually enticing and yet eminently readable, the book sets out both fundamental theory and principle to give the reader a thorough grounding in soil ecology. The author emphasises the interrelations between plants, animals and microbes. The fundamental physical and chemical properties of the soil habitat are clearly set out, enabling the reader to explore and understand the processes of soil nutrient cycling and the ecology of extreme soil environments. The book will appeal to advanced undergraduates and graduates in environmental science, plant science, ecology, microbiology and agriculture.
