Book excerpt: This book which is edited by Dr Bao-Luo Ma, a senior research scientist from Agriculture and Agri-Food in Canada, includes contributions from more than twenty-eight scientists in this dynamic field from around the world. This book synthesises the latest innovations and integrated knowledge from science disciplines as diverse as agronomy, soil science, ecology, economy, and social sciences. The global population is projected to reach nine billion by mid-century. Questions continue to arise concerning the ability of the agriculture sector to keep pace with the demands for food, feed, fibre and fuel of an increasing population in the near future, as well as finding a way of sustaining both the production system and the environment. Crop rotations, an ancient practice that has gained renewed interest in recent years, involve growing different crop species/varieties on the same piece of land in consecutive growing seasons (years). The direct and indirect benefits of this practice to the production system and the environment have been recognised for millennia. In recent years, it has been documented that crop rotations coupled with conservation tillage has enhanced the physical, chemical and biological properties of soil, improved seasonal nitrogen availability, and provided nitrogen inputs through symbiotic nitrogen fixation by legumes. This strategy can also lead to a better balance of plant nutritional requirements and a shift in soil mycorrhizal populations, interrupt insect populations, increase root activity, reduce disease severity, enhance environmentally-friendly biodiversity, and lower per-area greenhouse gas emissions or per-yield based carbon footprints. This book serves as one of the most recent and valuable reference on these multi-disciplines, and targets audiences at the undergraduate and graduate level, including crop, soil and agronomy scientists as well as environment scientists and policy-makers.

Download or read book Biological Nitrogen Fixation for Sustainable Agriculture written by J.K. Ladha and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical fertilizers have had a significant impact on food production in the recent past, and are today an indispensable part of modern agriculture. On the other hand, the oil crisis of the 1970s and the current Middle East problems are constant reminders of the vulnerability of our fossil fuel dependent agriculture. There are vast areas of the developing world where N fertilizers are neither available nor affordable and, in most of these countries, balance of payment problems have resulted in the removal of N fertilizer subsidies. The external costs of environmental degradation and human health far exceed economic concerns. Input efficiency of N fertilizer is one of the lowest and, in turn, contributes substantially to environmental pollution. Nitrate in ground and surface waters and the threat to the stability of the ozone layer from gaseous oxides of nitrogen are major health and environmental concerns. The removal of large quantities of crop produce from the land also depletes soil of its native N reserves. Another concern is the decline in crop yields under continuous use of N fertilizers. These economic, environmental and production considerations dictate that biological alternatives which can augment, and in some cases replace, N fertilizers must be exploited. Long-term sustainability of agricultural systems must rely on the use and effective management of internal resources. The process of biological nitrogen fixation offers and economically attractive and ecologically sound means of reducing external nitrogen input and improving the quality and quantity of internal resources. In this book, we outline sustainability issues that dictate an increased use of biological nitrogen fixation and the constraints on its optimal use in agriculture.
Download or read book Nitrogen in Agriculture written by Takuji Ohyama and published by BoD – Books on Demand. This book was released on 2021-09-29 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is the most important nutrient in agricultural practice because the availability of nitrogen from the soil is generally not enough to support crop yields. To maintain soil fertility, the application of organic matters and crop rotation have been practiced. Farmers can use convenient chemical nitrogen fertilizers to obtain high crop yields. However, the inappropriate use of nitrogen fertilizers causes environmental problems such as nitrate leaching, contamination in groundwater, and the emission of N2O gas. This book is divided into the following four sections: “Ecology and Environmental Aspects of Nitrogen in Agriculture”, “Nitrogen Fertilizers and Nitrogen Management in Agriculture”, “N Utilization and Metabolism in Crops”, “Plant-Microbe Interactions”.

Download or read book North American Agroforestry written by Harold E. Gene Garrett and published by John Wiley & Sons. This book was released on 2022-02-23 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: North American Agroforestry Explore the many benefits of alternative land-use systems with this incisive resource Humanity has become a victim of its own success. While we’ve managed to meet the needs—to one extent or another—of a large portion of the human population, we’ve often done so by ignoring the health of the natural environment we rely on to sustain our planet. And by deteriorating the quality of our air, water, and land, we’ve put into motion consequences we’ll be dealing with for generations. In the newly revised Third Edition of North American Agroforestry, an expert team of researchers delivers an authoritative and insightful exploration of an alternative land-use system that exploits the positive interactions between trees and crops when they are grown together and bridges the gap between production agriculture and natural resource management. This latest edition includes new material on urban food forests, as well as the air and soil quality benefits of agroforestry, agroforestry’s relevance in the Mexican context, and agroforestry training and education. The book also offers: A thorough introduction to the development of agroforestry as an integrated land use management strategy Comprehensive explorations of agroforestry nomenclature, concepts, and practices, as well as an agroecological foundation for temperate agroforestry Practical discussions of tree-crop interactions in temperate agroforestry, including in systems such as windbreak practices, silvopasture practices, and alley cropping practices In-depth examinations of vegetative environmental buffers for air and water quality benefits, agroforestry for wildlife habitat, agroforestry at the landscape level, and the impact of agroforestry on soil health Perfect for environmental scientists, natural resource professionals and ecologists, North American Agroforestry will also earn a place in the libraries of students and scholars of agricultural sciences interested in the potential benefits of agroforestry.
Download or read book Crop Rotation written by Samiha Ouda and published by Springer. This book was released on 2018-12-06 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tackles the issue of using crop rotation to increase food production and secure it for the growing population of the future. Crop rotation can be a solution of food gaps in the developing counties. Crop rotation plays an important role in attaining soil sustainability and in controlling pests and weeds. It can alleviate damage caused by climate change by reducing losses in productivity of the crops, minimizing soil fertility loss and increase irrigation water productivity. This book also includes the reviews of a large number of crop rotations that have been published internationally, and additionally, the crop rotations that have been implemented in Egypt have a unique characteristic to them and therefore, a large number of those reviews have also been included.

Download or read book The Pesticide Detox written by Jules N. Pretty and published by Earthscan. This book was released on 2012-07-26 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1960s, the world's population has more than doubled and agricultural production per person has increased by a third. Yet this growth in production has masked enormous hidden costs arising from widespread pesticide use - massive ecological damage and high incidences of farmer poisoning and chronic health effects. Whereas once the risks involved with pesticide use were judged to be outweighed by the potential benefits, increasingly the external costs of pesticides, to environments and human health, are being seen as unacceptable. In response to this trend, recent years have seen millions of farmers in communities around the world reduce their use of harmful pesticides and develop cheaper and safer alternatives. The Pesticide Detox explores the potential for the phasing-out of hazardous pesticides and the phasing-in of cost effective alternatives already available on the market. This book makes clear that it is time to start the pesticide detox and to move towards a more sustainable agriculture.
