Download or read book Organic Crop Production Ambitions and Limitations written by Holger Kirchmann and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many people believe that organic agriculture is a solution for various problems related to food production. Organic agriculture is supposed to produce healthier products, does not pollute the environment, improves the fertility of soils, saves fossil fuels and enables high biodiversity. This book has been written to provide scientifically based information on organic agriculture such as crop yields, food safety, nutrient use efficiency, leaching, long-term sustainability, greenhouse gas emissions and energy aspects. A number of scientists working with questions related to organic agriculture were invited to present the most recent research and to address critical issues. An unbiased selection of literature, facts rather than standpoints, and scientifically-based examinations instead of wishful thinking will help the reader be aware of difficulties involved with organic agriculture. Organic agriculture, which originates from philosophies of nature, has often outlined key goals to reach long-term sustainability but practical solutions are lacking. The central tasks of agriculture - to produce sufficient food of high quality without harmful effects on the environment - seem to be difficult to achieve through exclusively applying organic principles ruling out many valuable possibilities and solutions.

Download or read book ORGANIC VEGETABLE PRODUCTION written by Gareth Davies and published by Crowood. This book was released on 2012-08-01 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic Vegetable Production provides an invaluable, practical guide to the production of organic vegetables across a range of organic farming systems in temperate areas. The book covers all aspects of production, including crop choice, fertility building and weed, pest and disease management within a framework of rotation design and business planning. The specific needs of a range of commonly grown vegetable crops are discussed in detail. The authors consider that knowledge-gathering, marketing and financial management are integral parts of organic vegetable production and these subjects are examined in depth. Speciality topics as protected cropping and storage are covered. The book highlights the technical and economic consequences of converting from conventional to organic production and the challenges that can arise.

Book excerpt: This volume contains the proceedings of the workshop on "Soil Monitoring: Methods for Early Detection and Surveying of Soil Contamination and Degradation", held at the ETH seminar centre "Stefano Franscini" of Monte Verita, Ascona (Switzerland) from October 18 - 23, 1992. Seventy participants, representing a variety of institutions, nations, and disciplines, discussed the concepts, approaches, status, gaps, problems, and perspectives of soil pollution monitoring. The idea for this workshop came from A. Desaules when he was installing the Swiss National Soil Monitoring Network (NABO) as his doubts about the philosophy of soil monitoring prevailing at that time increased. This philosophy essentially equated soil mo nitoring with repetitive surveys of soil pollutant concentrations at pennanent observation sites. He sought others interested in discussing alternatives, and he found a ready partner in the ETH-Institute for Terrestrial Ecology. Soon it was realized that a discussion of the NABO would immediately raise general questions with respect to the conceptual basis of soil monitoring and that a minimum agreement on this basis was indispensable to discuss more specific problems related to the realization of the NABO. As a result, a workshop was organized whose objectives were in particular (i) an assessment of current knowledge on soil monitoring by pennanent networks, (ii) a syn thesis of the experience from different disciplines related to soil monitoring, (iii) the identification ofresearch gaps with respect to long-tenn and large-scale soil monitoring, and (iv) the design of a platfonn for the development of soil monitoring strategies and methodology.
