Download or read book Nitrogen in the Environment Sources Problems and Management written by R.F. Follett and published by Gulf Professional Publishing. This book was released on 2001-12-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.

Download or read book Novel Ways and Methodologies to Improve Crop Yield written by Oorbessy Gaju and published by Frontiers Media SA. This book was released on 2024-11-01 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global population is increasing at a much faster pace than an increase in the genetic gain for food production by plant breeding. Therefore, we must find ways or methods to improve our food production if we are to ensure food security for all. This special edition is about the novel ways or methodologies that crop or plant scientists are working on to improve crop yield. This could fall under the physiological, biochemical, molecular, or even any novel technological approaches such as phenotyping to rapidly select or find traits that are vital for the improvement of current germplasm to make them resilient to an ever-changing environment. Crop yield, especially grain yield, is a very complex trait to deconvolute and understand as it is influenced by so many factors. With the recent unprecedented weather events where plants are subjected to extreme temperatures (low and high), it is imperative to find ways quickly to screen for varieties that can withstand these changes. Novel ways or methods in the various disciplines (physiology, molecular, phenotyping, biochemical) that can help to identify rapidly the traits related to yield in crops that can lead to an increase in productivity will be informative and help the scientific community to be up to date with recent progress.
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.
