Download or read book Managing Cover Crops Profitably 3rd Ed written by Andy Clark and published by DIANE Publishing. This book was released on 2008-07 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

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.

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”.
