Available in PDF, EPUB and Kindle. Book excerpt: Cover Crops and Soil Ecosystem Services A comprehensive resource on cover crops and their role in soil ecosystems Cover crops are a reemerging strategy to improve and maintain the services that soils provide. They can have an enormous affect on agricultural outcomes, preventing soil erosion, restoring vital soil nutrients, sequestering C from the atmosphere, and more. The successful management and use of cover crops is therefore critical to ensure soil ecosystem services are maintained or improved not only to meet our demands for food, fuel, fiber, and feed but also to reduce pollution and improve the soil. Cover Crops and Soil Ecosystem Services provides a heavily researched and highly readable introduction to cover crops and their role in soil ecosystems. It ranges from a detailed discussion of cover crop biomass production to a thorough treatment of soil ecosystems and their vulnerabilities. The result is an essential guide to a critical area of agricultural science. Cover Crops and Soil Ecosystem Services readers will also find: Detailed treatment of cover crop biomass production, soil erosion, greenhouse gas fluxes, nitrate leaching, soil C sequestration, and more Discussion of emerging issues, including extreme weather events and the economics of cover crop farming Wide-ranging summaries of interdisciplinary soil and cover crop research Cover Crops and Soil Ecosystem Services is a useful reference for students and researchers at all levels of study relating to cover crop agriculture.

Download or read book Nitrogen Management in Crop Production written by Nand Kumar Fageria and published by CRC Press. This book was released on 2014-06-25 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main approaches for safeguarding food security, sustainable development has increased demand for knowledge on fertilizer management in crop production. Among essential plant nutrients, nitrogen is one of the most important yield-limiting nutrients, mainly responsible for determining yield and yield components in cereals and legumes. It is also responsible for the activation of many enzymes and, of course, plays an important role in photosynthesis. With a recovery efficiency of less than 50 percent in most cropping systems, a large portion of the nitrogen applied as fertilizer is not used by plants, creating environmental and economic issues. Nitrogen Management in Crop Production covers the critical aspects for the judicious use of nitrogen in cropping systems. This includes appropriate methods of nitrogen application, effective source and timing of application during crop growth cycles, use of an adequate application rate to avoid loss and reduce cost, use of nitrogen-efficient crop genotypes, and use of legumes that fix sufficient amounts of atmospheric nitrogen. There is also a chapter on organic matter and its role in sustainability. This book presents recent information from the international literature, making it relevant for most agroecological regions. Chapters provide experimental results to aid in practical application of the information. The book contains color photos of nitrogen deficiency symptoms to serve as a guide for important crop species, such as rice, dry bean, wheat, soybean, and corn. It also includes numerous tables and figures, providing an easy-to-read reference.

Book excerpt: An increasing number of farmers and scientists believe the foundational ideas of mainstream agronomy are incomplete and unsound. Conventional crop production ignores biology in favor of chemical interventions, leading farmers to buy inputs they don't need. Fertilizer recommendations keep going up, pest pressure becomes more intense, pesticide applications are needed more often, and soil health continues to degrade. However, innovative growers and researchers are beginning to think differently about production agriculture systems. They have developed practices that regenerate soil and plant health and that deliver much better results than mainstream methods. Using these principles, growers are able to decrease fertilizer applications, reduce disease and insect pressure, hold more water in the soil, improve soil health, and grow crops that are more resilient to climatic extremes, increasing farm profitability immediately. As a leading agronomist and teacher, John Kempf has implemented regenerative agricultural systems on millions of acres across many different crop types and growing regions with his team at Advancing Eco Agriculture. In Quality Agriculture, John interviews a group of growers, consultants, and scientists who describe how to think and farm differently in order to produce exceptional results in the field. Their remarkable insights will challenge you, encourage you, and inspire gratitude and joy for the rewards of working with natural systems.
