Download or read book Nitrogen in Agricultural Landscape written by Lech Wojciech Szajdak and published by CRC Press. This book was released on 2021-06-17 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture transforms the environment. The simplification of agroecosystems structure increases the hazards of leaching, wind and water erosion, and volatilization of chemicals from soil. Soil nitrogen is of interest as a major crop nutrient, but also as a potential environmental pollutant. Knowledge about the behavior of soil nitrogen is desirable in order to optimize plant growth and crop yield and to minimize environmental side effects. This book also gives information about the function of biogeochemical barriers in the form of shelterbelts, which efficiently decrease the concentrations of various forms of nitrogen in ground water.

Available in PDF, EPUB and Kindle. Book excerpt: Presenting the first continental-scale assessment of reactive nitrogen in the environment, this book sets the related environmental problems in context by providing a multidisciplinary introduction to the nitrogen cycle processes. Issues of upscaling from farm plot and city to national and continental scales are addressed in detail with emphasis on opportunities for better management at local to global levels. The five key societal threats posed by reactive nitrogen are assessed, providing a framework for joined-up management of the nitrogen cycle in Europe, including the first cost-benefit analysis for different reactive nitrogen forms and future scenarios. Incorporating comprehensive maps, a handy technical synopsis and a summary for policy makers, this landmark volume is an essential reference for academic researchers across a wide range of disciplines, as well as stakeholders and policy makers. It is also a valuable tool in communicating the key environmental issues and future challenges to the wider public.
Download or read book A Framework for Assessing Effects of the Food System written by National Research Council and published by National Academies Press. This book was released on 2015-06-17 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.

Book excerpt: If you?re an agronomist, horticulturalist, plant and soil scientist, breeder, or soil microbiologist, you?ll want to read Nutrient Use in Crop Production to find everything you need to know about judicious nutrient management and maximizing nutrient utilization in the agricultural landscape. In this book, you?ll discover ways to minimize undesirable nutrient losses and techniques for preserving the environment while meeting the challenges of providing the earth?s increasing population with sufficient food, feed, and fiber to sustain life. Your existing knowledge base concerning this vital area of science will expand and grow as you become more open to the new ideas and applications contained in Nutrient Use in Crop Production. Most importantly, you?ll avoid the narrow scope found in most crop nutrition books and take a broader, more globally minded view of how to maximize nutrient use and minimize nutrient losses in the soil of agricultural systems. Specifically, you?ll find these and other areas covered: population growth, food production, and nutrient requirements managing soil fertility decline the role of nitrogen fixation in crop production delivering fertilizers through seed coatings micronutrient fertilizers the role of nutrient-efficient crops in modern agriculture Feeding the world without depleting the world?s viable soil nutrients is a monumental task--but one that can be achieved, as evidenced in the pages of Nutrient Use in Crop Production. You and your circle of students, professionals, and administrators will benefit greatly from this in-depth view of nutrient use in both developed and non-industrialized counties to give you a better sense of how to allow both the world and the world?s crops to grow.
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 Exploring and Optimizing Agricultural Landscapes written by Lothar Mueller and published by Springer Nature. This book was released on 2021-06-14 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book informs about agricultural landscapes, their features, functions and regulatory mechanisms. It characterizes agricultural production systems, trends of their development, and their impacts on the landscape. Agricultural landscapes are multifunctional systems, coupled with all nexus problems of the 21th century. This has led to serious discrepancies between agriculture and environment, and between urban and rural population. The mission, key topics and methods of research in order to understanding, monitoring and controlling processes in rural landscapes is being explained. Studies of international expert teams, many of them from Russia, demonstrate approaches towards both improving agricultural productivity and sustainability, and enhancing ecosystem services of agricultural landscapes. Scientists of different disciplines, decision makers, farmers and further informed people dealing with the evolvement of thriving rural landscapes are the primary audience of this book.

Available in PDF, EPUB and Kindle. Book excerpt: In the tradition of Jared Diamond's Guns, Germs, and Steel, this gives the very early history of how human ingenuity overcame the risk of famine through productive agriculture. Starting with a layman's guide to the chemistry of nitrogen fixation, the book goes on to show how humans emerged from nomadic lifestyles and began developing towns and settlements. When they for the first time began planting the same fields year after year, they noticed quickly the need to ensure soil fertility. But how? The method they came up with is still in use to this day.
