Book Description
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.

Book Description
With global revenue surpassing twenty-five billion dollars annually, organic agriculture is a highly visible and rapidly growing component of agricultural production. In Organic Agriculture: A Global Perspective, Paul Kristiansen, Acram Taji, and John Reganold, and their international group of contributors scientifically review key aspects of organic agriculture. At the intersection of research, education, and practice, the contributors look at the organic agricultural movement’s successes and limitations. The first half of this book critically evaluates the agricultural production of both plants and livestock in organic farming systems. All major aspects of organic agriculture are explored, including historical background and underlying principles, soil-fertility management, crop and animal production, breeding strategies, and crop protection. This global and comprehensive overview also addresses the economic, social, and political aspects of organic farming. These include economics and marketing; standards and certification; environmental impacts and social responsibility; and research, education, and extension. The book is a unique and timely science-based international work documenting current practices in organic agriculture and evaluating their strengths and weaknesses. For more than two decades, research into organic methods by mainstream scientists has generated a large body of information that can now be integrated and used for assessing the actual impacts of organic farming in a wide range of disciplines. The knowledge of selected international experts has been combined in one volume, providing a comprehensive review of organic farming globally. Researchers, teachers, extensionists, students, primary producers and others around the world who are interested in sustainable agriculture will find this book to be a valuable and reliable resource.

Book Description
Abstract: A comprehensive USDA study of organic farming inthe U.S., Japan, and Europe is focused on the rationales for choosing this method, the sociopolitical influences,technology and management systems, economic factors andsuccess, research and educational needs, and implementationmethods. Interest in organic farming is increasing as theadverse effects of intensive chemical farming become betterknown, such as costs and availability of energy and chemical fertilizer, decline of soil productivity, environmentalpollution, health hazards, and the decline of the familyfarm and local marketing. A few of the findings of the study are that the organic farming movement covers a widespectrum of practice and is not limited by size; ismotivated by concerns for conservation, health, and costcontrol; uses modern techniques, equipment, and managementpractices; is suited to crop-livestock interdependence; andis more labor intensive, less energy consuming, and lessprofitable than conventional farming.

Book Description
Organic farming aims to produce a number of crops, without the use of synthetic chemicals (pesticides) or fertilizers, while enhancing soil composition and promoting biodiversity. This is a traditional, more permanent type of farming that relies on ecosystem services to maintain the integrity of the landscape while still producing sufficient yields. In addition, conventional farming uses pesticides and fertilizers to maximize the yield of a particular crop or set of crops, which are typically genetically modified. This book covers several issues related to the multi-functionality and impacts of organic and conventional farming systems. Chapters cover topics related to organic farming and the economy, farm management, and innovative methods and approaches.

Book Description
Modern agriculture and food systems, including organic agriculture, are undergoing a technological and structural modernisation and are faced with a growing globalisation. Organic agriculture (OA) can be seen as pioneering efforts to create sustainable development based on other principles than mainstream agriculture. There are however large differences between the challenges connected to, on one hand, modern farming and consumption in high-income countries and, on the other, smallholder farmers and resource poor consumers in low-income countries. The point of departure is the increasing globalisation and the production and trade of food and fodder and how this influences the role of OA. This book provides an overview of the potential role and challenges of organic agriculture in this global perspective, as seen from different perspectives such as sustainability, food security and fair trade.

Book Description
Organic farming comes with many connotations of ‘natural’, ‘wholesome’, ‘healthy’, ‘superior’, ‘environmentally friendly’, and ‘sustainable’. But just what is the scientific evidence behind the claims of healthier food and better farming systems made by the organic movement? Using peer reviewed literature, the latest studies and a rigorous investigation of claims made by opponents of conventional farming, the author provides an even handed and scientifically objective review of the contributions of organic farming to human health, crop yields, the environment and agriculture from a global perspective. The aim is to separate out the marketing spin, the claims of one camp or another and political ideologies to provide a straightforward appraisal of both the benefits and exaggerated claims of organic farming. The approach taken is to present the evidence – in the form of data, study results and presentation of source material for the claims made by conventional and organic, and leave the reader to make their own judgements on the validity of the case for organic over conventional farming. The book also addresses a fundamental question in modern farming – organic agriculture’s ability to feed the world in the face of a growing population and growing demand for meat, and provides a timely scientific comparison of the practices, relative yields and benefits of organic versus conventional agriculture. The ways conventional farming has progressed from hunter gatherer days and possible future developments are discussed. Conventional and Organic Farming is an ideal book for agricultural policy makers, researchers and academics, as well as agricultural students, conventional and organic farmers. 5m Books

Book Description
Fertilizer application can increase crop yields and improve global food security, and thus has the potential to eliminate hunger and poverty. However, excessive amounts of fertilizer application can contribute to groundwater pollution, greenhouse gas emissions, eutrophication, deposition and disruptions to natural ecosystems, and soil acidification over time. Small farmers in many countries think inorganic fertilizers are expensive and degrade soils, and thus policymakers want to promote organic instead of inorganic fertilizers. To develop practical fertilizer recommendations for farmers, yield responses to applied fertilizers from inorganic and organic sources, indigenous nutrient supply from soil, and nutrient use efficiency require consideration. There is a lack of sufficient scientific understanding regarding the need and benefit of integrated nutrient management (i.e., judicious use of inorganic and organic sources of nutrients) to meet the nutrient demand of high-yielding crops, increase yields and profits, and reduce soil and environmental degradation. Inadequate knowledge has constrained efforts to develop precision nutrient management recommendations that aim to rationalize input costs, increase yields and profits, and reduce environmental externalities. This Special Issue of the journal provided some evidence of the usefulness of integrated nutrient management to sustain soil resources and supply nutrients to crops grown with major cereal and legume crops in some developing countries.

Book Description
This book provides a timely analysis and assessment of the potential of organic agriculture (OA) for rural development and the improvement of livelihoods. It focuses on smallholders in developing countries and in countries of economic transition, but there is also coverage of and comparisons with developed countries. It covers market-oriented approaches and challenges for OA as part of high value chains and as an agro-ecologically based development for improving food security. It demonstrates the often unrecognised roles that organic farming can play in climate change, food security and sovereignty, carbon sequestration, cost internalisations, ecosystems services, human health and the restoration of degraded landscapes. The chapters specifically provide readers with: an overview of the state of research on OA from socio-economic, environmental and agro-ecological perspectives an analysis of the current and potential role of OA in improving livelihoods of farmers, in sustainable value chain development, and in implementation of agro-ecological methods proposed strategies for exploiting and improving the potential of OA and overcoming the constraints for further development a review of the strengths and weaknesses of OA in a sustainable development context
