Dynamic optimization of crop production with nonuniform irrigation and nitrogen carryover and leaching is considered. A production function system with thresholds, plateau maximum, and yield reduction is estimated from experimental data; rapid convergence to a steady-state is observed. Spatial variability implies a 40% increase in applied water and a six-fold increase in nitrate emissions, while dynamic optimization has more modest impacts. Nitrate emission control is accomplished primarily through reduced applied water, illustrating a strong cross-policy effect. Significant levels of water conservation and nitrate pollution control are achieved at relatively low cost with traditional irrigation systems and baseline conditions.

Download Nitrogen Management in Irrigated Agriculture Book in PDF, ePub and Kindle
Nitrogen constitutes about 79 percent of the earth's atmosphere, yet, in an agricultural plant production system, it is still common for soils to be deficient in the nitrogen needed for maximum plant growth. Nitrogen fertilizers, however, despite being essential for the economically driven production of food and fiber, are recognized as polluters of natural waters, and it has become increasingly apparent that manufactured and naturally occurring nitrogen resources must be better managed. This book addresses the problem by describing how such factors as types of soils and crops, irrigation methods, climate, and the nitrogen cycle itself affect levels of nitrogen in agricultural plant production systems. The book also provides a practical guide to the use of different fertilizers with regard to environment, type of plant, and method of farming. This book will help to achieve effective nitrogen management in agriculture and will be of interest to workers in local, state, and federal agricultural extension services, consulting firms, environmental regulators, and students and researchers in soil chemistry.

Download Adaptation and Resilience Book in PDF, ePub and Kindle
In America's arid southwest, climate change will occur in the context of already-keen competition for water for agriculture, urban growth, electricity generation, water-based recreation, and environmental protections. This book explores the challenges that climate change and variability pose for water and energy managers and users, communities, and policy makers in the arid Southwest and demonstrates the application of economic methods to address these challenges. It provides valuable tools for both those interested in resource management and climate change, and those seeking to understand how economic methods can be used to analyze contemporary social problems and craft appropriate responses. The book considers both adaptation to long-term climate change and more immediate issues of water and electricity management in the face of inter-annual climate variability and drought. Thus, no matter what one's perspective on long-run climate change projections, the book provides useful lessons for some of the region's most pressing resource management problems.

Download Advances in Efficiency and Productivity Analysis Book in PDF, ePub and Kindle
The volume examines the state-of-the-art of productivity and efficiency analysis. It brings together a selection of the best papers from the 10th North American Productivity Workshop. By analyzing world-wide perspectives on challenges that local economies and institutions may face when changes in productivity are observed, readers can quickly assess the impact of productivity measurement, productivity growth, dynamics of productivity change, measures of labor productivity, measures of technical efficiency in different sectors, frontier analysis, measures of performance, industry instability and spillover effects. The contributions in this volume focus on the theory and application of economics, econometrics, statistics, management science and operational research related to problems in the areas of productivity and efficiency measurement. Popular techniques and methodologies including stochastic frontier analysis and data envelopment analysis are represented. Chapters also cover broader issues related to measuring, understanding, incentivizing and improving the productivity and performance of firms, public services, and industries.

Download The California Nitrogen Assessment Book in PDF, ePub and Kindle
Nitrogen is indispensable to all life on Earth. However, humans now dominate the nitrogen cycle, and nitrogen emissions from human activity have real costs: water and air pollution, climate change, and detrimental effects on human health, biodiversity, and natural habitats. Too little nitrogen limits ecosystem processes, while too much nitrogen transforms ecosystems profoundly. The California Nitrogen Assessment is the first comprehensive account of nitrogen flows, practices, and policies for California, encompassing all nitrogen flows—not just those associated with agriculture—and their impacts on ecosystem services and human wellbeing. How California handles nitrogen issues will be of interest nationally and internationally, and the goal of the assessment is to link science with action and to produce information that affects both future policy and solutions for addressing nitrogen pollution. This book also provides a model for application of integrated ecosystem assessment methods at regional and state (subnational) levels.

Download Nitrogen Management and Ground Water Protection Book in PDF, ePub and Kindle
Supplying crops with adequate nitrogen is vital to ensuring food supplies. Once nitrogen is added to the soil, it is subject to chemical transformations of the nitrogen-cycle including transformation to nitrate. Excessive amounts of accumulated nitrate may then leach out of the soil and could potentially enter and contaminate drinking water supplies. The purpose of this book is to examine the subject of nitrogen management and ground water protection. The issue of maintaining ground water quality is addressed primarily from an agronomic point of view. Topics covered include: health and economic aspects of nitrate in drinking water; nitrate sources; ground water nitrate in the USA and other developed countries; transport, leaching and accounting for nitrogen; soil, nitrogen, crop and water management; and nitrate in aquifer systems. The book contains a keyword index and is organized into thirteen chapters, each with appropriate references, tables and figures. Chapter authors are among the leading experts on the subject of nitrate and ground water quality. Readers to whom the book is directed include soil scientists and agronomists, agricultural engineers (irrigation and drainage), environmental scientists, agricultural policy makers, and hydrologists.
