Book Description
Maize is among the most widely spread and widely used crops of the world, used for cereals for over 4 billion humans, as food for farm animals, and as a source material for biofuel production. Yet there are relatively few books on the cropping system of this important crop. This book, Maize Agroecosystem, is a concise treatise dealing with agronomy, soil fertility, and productivity of maize. The information is global in nature and considers recent developments in all maize cropping belts. The "global maize agroecosystem" is a conglomerate of several "maize cropping belts" that flourish on different continents. The impact of nutrient management on the productivity of maize agroecosystems is the main focus of this book. The book includes the history of maize growing, the kinds of soil needed, nutrient dynamics, the use of soil organic matter, the physiology and genetics of maize, and integrated nutrient management. It presents comprehensive knowledge regarding the physicochemical dynamics of the three major nutrients: nitrogen, phosphorus, and potassium. Also covered is how fertilizers impinge on soils of maize farms and their impact on soil and groundwater quality. The impact of crop genotype on soil nutrient dynamics and productivity is also highlighted. The information provided here will be highly useful to students at colleges and universities in the fields of agricultural sciences and environmental science and ecology, and the book also functions as valuable resource for researchers and professors in crop science. Several figures and tables are included that describe and summarize the impact of various agronomic/fertilizer management procedures on crop productivity.

Book Description
As appreciation of the interdisciplinary and multidimensional character of environmental issues has increased, there have been attempts to address regional needs more directly. One of these, the Regional Marine Research Program (RMRP), was established by Congress in 1990 to provide a mechanism to fund coastal marine research based on regionally-defined priorities. The RMRP legislation established a system of nine regional marine research boards around the United States. Each board was responsible for planning marine research to address issues of water quality and ecosystem health on a regional scale. Although all nine regions received funding for planning activities and development of a research plan, only the Gulf of Maine RMRP received funding for program implementation. The completion of the Gulf of Maine program, in 1997, presents an opportunity to evaluate whether the process for planning and managing the Gulf of Maine research was adequate, whether the research fulfilled the goals of the program, and whether this experience should serve as a model for similar regional programs elsewhere. Bridging Boundaries through Regional Marine Research is a study of the RMRP, with a specific review of the Gulf of Maine program as well as an assessment of other modesl for regional marine research. This report assesses the need for regional marine research,reviews processes by which regional marine research needs can be defined, and discusses existing programs for regional marine research in the United States. It also identifies short- and long-term approaches that might be taken by NOAA.

Book Description
The transportation sector cannot continue on its current path: The volatility of oil prices threatens the U.S. economy, the large proportion of oil importation threatens U.S. energy security, and the massive contribution of greenhouse gases threatens the environment. The development of domestic sources of alternative transportation fuels with lower greenhouse emissions is now a national imperative. Coal and biomass are in abundant supply in the United States and can be converted to liquid fuels that can be combusted in existing and future vehicles. Their abundant supply makes them attractive candidates to provide non-oil-based liquid fuels to the U.S. transportation system. However, there are important questions about the economic viability, carbon impact, and technology status of these options. Liquid Transportation Fuels from Coal and Biomass provides a snapshot of the potential costs of liquid fuels from biomass by biochemical conversion and from biomass and coal by thermochemical conversion. Policy makers, investors, leaders in industry, the transportation sector, and others with a concern for the environment, economy, and energy security will look to this book as a roadmap to independence from foreign oil. With immediate action and sustained effort, alternative liquid fuels can be available in the 2020 time frame, if or when the nation needs them.

Book Description
This open access book highlights concepts discussed at two international conferences that brought together world-renowned scientists to advance the science of potassium (K) recommendations for crops. There was general agreement that the potassium recommendations currently in general use are oversimplified, outdated, and jeopardize soil, plant, and human health. Accordingly, this book puts forward a significantly expanded K cycle that more accurately depicts K inputs, losses and transformations in soils. This new cycle serves as both the conceptual basis for the scientific discussions in this book and a framework upon which to build future improvements. Previously used approaches are critically reviewed and assessed, not only for their relevance to future enhancements, but also for their use as metrics of sustainability. An initial effort is made to link K nutrition in crops and K nutrition in humans. The book offers an invaluable asset for graduate students, educators, industry scientists, data scientists, and advanced agronomists.

Book Description
Traditional agricultural practices face escalating environmental challenges and struggle to meet global food demands while ensuring soil health and sustainability. Soil degradation, exacerbated by factors like industrialization and urbanization, significantly threatens crop productivity and food security. Conventional remediation methods often need to be revised, requiring innovative approaches to restore soil health and fertility. Nanotechnology Applications and Innovations for Improved Soil Health presents a groundbreaking solution to this pressing issue, offering a comprehensive guide to leveraging nanotechnology for sustainable agriculture. This pioneering book explores the transformative potential of nanomaterials in enhancing soil quality and crop production. By harnessing the unique properties of nanomaterials, such as their high surface area and reactivity, researchers and practitioners can develop novel strategies to address soil degradation and improve nutrient availability. By systematically examining nanotechnology's role in soil health, this book equips readers with the knowledge and tools needed to revolutionize agricultural practices and ensure food security for future generations.

Book Description
We are entering a new era in production agronomics. Agricultural scientists the world over call for the development of techniques that simultaneously increase soil carbon storage and reduce agriculture's energy use. In response, site-specific or precision agriculture has become the focus and direction for the three motivating forces that are changi
