Galloway and you can download with pub, pdf, txt, doc, and more file format with free account. the production of food and energy interfere with the natural nitrogen cycle of the earth. many of these changes are beneficial, while others are detrimental to societies and the environment. the changing nature of nitrogen in the global environment crosses scientific disciplines, geographical boundaries and political divisions and challenges the creative minds of natural and social scientists, economists, engineers, business leaders and planners. the papers in this book give readers a panoramic view of the changing nature of reactive nitrogen in the global environment, enabling them to make better choices about nitrogen management in food production and consumption, energy production and use, and environmental protection.

Description : Read Now Nutrient Use Efficiency From Basics To Advances by Amitava Rakshit and you can download with pub, pdf, txt, doc, and more file format with free account. this book addresses in detail multifaceted approaches to boosting nutrient use efficiency (nue) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects. conveying an in-depth understanding of the topic will spark the development of new cultivars and strains to induce nue, coupled with best management practices that will immensely benefit agricultural systems, safeguarding their soil, water, and air quality. written by recognized experts in the field, the book is intended to provide students, scientists and policymakers with essential insights into holistic approaches to nue, as well as an overview of some successful case studies. in the present understanding of agriculture, nue represents a question of process optimization in response to the increasing fragility of our natural resources base and threats to food grain security across the globe. further improving nutrient use efficiency is a prerequisite to reducing production costs, expanding crop acreage into non-competitive marginal lands with low nutrient resources, and preventing environmental contamination. the nutrients most commonly limiting plant growth are n, p, k, s and micronutrients like fe, zn, b and mo. nue depends on the ability to efficiently take up the nutrient from the soil, but also on transport, storage, mobilization, usage within the plant and the environment. a number of approaches can help us to understand nue as a whole. one involves adopting best crop management practices that take into account root-induced rhizosphere processes, which play a pivotal role in controlling nutrient dynamics in the soil-plant-atmosphere continuum. new technologies, from basic tools like leaf color charts to sophisticated sensor-based systems and laser land leveling, can reduce the dependency on laboratory assistance and manual labor. another approach concerns the development of crop plants through genetic manipulations that allow them to take up and assimilate nutrients more efficiently, as well as identifying processes of plant responses to nutrient deficiency stress and exploring natural genetic variation. though only recently introduced, the ability of microbial inoculants to induce nue is gaining in importance, as the loss, immobilization, release and availability of nutrients are mediated by soil microbial processes.

Description : Read Now Ammonia Emissions In Agriculture by Gert-Jan Monteny and you can download with pub, pdf, txt, doc, and more file format with free account. ammonia emissions is an important topic in many countries with animal production, since it contributes to environmental and health problems. strategies and measures to reduce ammonia emission are getting increasing attention in national and international legislation.this book aims to bring together visions and knowledge from scientists, policy makers and other relevant stakeholders around the subject of nh3 emissions from agricultural operations and its reduction options. it also offers a basis for international harmonization on various nh3 emission related topics (e.g. national emission inventories, measurement techniques and strategies, data on emissions and reductions) and, last but not least, it provides an update of science concerning nh3 and related environmental issues.the focus of this publication is on nh3 emissions from various agricultural sources (grazing, animal housing, manure storage, land application of manures), and the options for their reduction in a farm system approach. also, multiple gaseous emissions, their reduction options and pollution swapping issues are adressed. environmental impact and health related effects of nh3 are briefly addressed.in conclusion, this book gives an overview of the current knowledge about ammonia emissions and how we can implement this knowledge in current agricultural systems.

Description : Read Now Livestock In A Changing Landscape Volume 1 by Henning Steinfeld and you can download with pub, pdf, txt, doc, and more file format with free account. the rapidly changing nature of animal production systems, especially increasing intensification and globalization, is playing out in complex ways around the world. over the last century, livestock keeping evolved from a means of harnessing marginal resources to produce items for local consumption to a key component of global food chains. livestock in a changing landscape offers a comprehensive examination of these important and far-reaching trends. the books are an outgrowth of a collaborative effort involving international nongovernmental organizations including the united nations food and agriculture organization (un fao), the international livestock research institute (ilri), the swiss college of agriculture (shl), the french agricultural research centre for international development (cirad), and the scientific committee for problems of the environment (scope). volume 1 examines the forces shaping change in livestock production and management; the resulting impacts on landscapes, land use, and social systems; and potential policy and management responses. volume 2 explores needs and draws experience from region-specific contexts and detailed case studies. the case studies describe how drivers and consequences of change play out in specific geographical areas, and how public and private responses are shaped and implemented. together, the volumes present new, sustainable approaches to the challenges created by fundamental shifts in livestock management and production, and represent an essential resource for policy makers, industry managers, and academics involved with this issue.

Description : Read Now Urban Stormwater Management In The United States by National Research Council and you can download with pub, pdf, txt, doc, and more file format with free account. the rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. these changes have degraded water quality and habitat in virtually every urban stream system. the clean water act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. this book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. a number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.
