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 Plant Analysis written by D Reuter and published by CSIRO PUBLISHING. This book was released on 1997 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Analysis: An Interpretation Manual 2nd Edition is an easily accessible compilation of data summarising the range of nutrient concentration limits for crops, pastures, vegetables, fruit trees, vines, ornamentals and forest species. This information is valuable in assessing the effectiveness of fertiliser programs and for monitoring longer term changes in crop nutritional status. New to this edition: *Volume and scope of information accessed from the literature has expanded several-fold. Interpretation criteria for 294 species have been compiled in the tables from more than 1872 published papers. *New chapter on nutrient criteria for forest species. *Includes guidelines for collecting, handling and analysing plant material. An entire chapter is devoted to the identification of nutrient deficiency and toxicity symptoms.

Download or read book Marschner s Mineral Nutrition of Plants written by Zed Rengel and published by Academic Press. This book was released on 2022-12-09 with total page 817 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding of the mineral nutrition of plants is of fundamental importance in both basic and applied plant sciences. The fourth edition of this book retains the aim of the first in presenting the principles of mineral nutrition in the light of current advances. Marschner's Mineral Nutrition of Plants, 4th Edition, is divided into two parts: Nutritional Physiology and Plant–Soil Relationships. In Part I, emphasis is put on uptake and transport of nutrients in plants, root–shoot interactions, role of mineral nutrition in yield formation, stress physiology, water relations, functions of mineral nutrients and contribution of plant nutrition to food nutritional quality, disease tolerance, and global nutritional security of human populations. In view of the increasing interest in plant–soil interactions. Part II focuses on the effects of external and internal factors on root growth, rhizosphere chemistry and biology, soil-borne ion toxicities, and nutrient cycling. Now with color figures throughout, this book continues to be a valuable reference for plant and soil scientists and undergraduate and graduate students in the fields of plant nutrition, nutritional physiology, and soil fertility. - Offers new content on the relationship between climate change, soil fertility and crop nutrition - Keeps overall structure of previous editions - Includes updates in every chapter on new developments, ideas and challenges
