An expanded, new and improved American Environmental History textbook for everyone! After years of teaching Environmental History at a major East Coast University without a textbook, Dr. Dan Allosso decided to take matters into his own hands. The result, American Environmental History, is a concise, comprehensive survey covering the material from Dan's undergraduate course. What do people say about the class and the text? "This was my first semester and this course has created an incredible first impression. If all of the courses are this good, I am going to really enjoy my time here. The course has completely changed the way I look at the world." (Student in 2014 class) "One of the few classes I'm really sad is ending, the subject matter is fascinating and Dan is a great guide to it. His approach should be required of all students as it teaches an appreciation for a newer and better way of living." (Student in 2014 class) "Allosso's lectures are fantastic. The best I have ever had. So impressed. The material is always extremely interesting and well-presented." (Student in 2015 class) "It is just a perfect course that I think should be mandatory if we want to save our planet and live responsibly." (Student in 2015 class) "A rare gem for an IB ESS teacher or any social studies teacher looking for an 11th or 12th grade supplementary text that aims to provide an historical context for the environmental reality in America today. Highly recommended." (District Curriculum Coordinator, 2016) "I was so impressed with this material that I am using it as a supplement for a course I teach at my college." (History and Environmental Studies Professor, 2017) Beginning in prehistory and concluding in the present, American Environmental History explores the ways the environment has affected the choices that became our history, and how our choices have affected the environment. The dynamic relationship between people and the world around them is missing from mainstream history. Putting the environment back into history helps us make sense of the past and the present, which will help guide us toward a better future.

About 5% of all U.S. cropland is currently fertilized with livestock manure. Expanded environmental regulation through nutrient management plans will likely lead to wider use of manure on cropland, at higher production costs, but with only modest impacts on commodity demand, or farm structure. While current use is limited, expanded gov¿t. support could lead to a substantial increase in manure use as a feedstock. However, current energy processes are unlikely to compete with fertilizer uses of manure, because they leave fertilizer nutrients as residues, in more marketable form, and because manure-to-energy projects will be most profitable in regions where raw manure is in excess supply, with the least value as fertilizer.

The good practice guidelines - which form the basis of an interactive policymaker's tool kit included on a CD accompanying the book - relate not only to the more focused problem of encouraging increased fertilizer use by farmers, but also to the broader challenge of creating the type of enabling environment that is needed to support the emergence of efficient, dynamic and commercially viable fertilizer marketing systems."--Jacket.

Soil and Fertilizers: Managing the Environmental Footprint presents strategies to improve soil health by reducing the rate of fertilizer input while maintaining high agronomic yields. It is estimated that fertilizer use supported nearly half of global births in 2008. In a context of potential food insecurity exacerbated by population growth and climate change, the importance of fertilizers in sustaining the agronomic production is clear. However, excessive use of chemical fertilizers poses serious risks both to the environment and to human health. Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers. Written by an interdisciplinary author team, this book presents methods for enhancing the efficiency of fertilizer use and outlines agricultural practices that can reduce the environmental footprint. Features: Includes a thorough literature review on the agronomic and environmental impact of fertilizer, from degradation of ecosystems to the eutrophication of drinking water Devotes specific chapters to enhancing the use efficiency and effectiveness of the fertilizers through improved formulations, time and mode of application, and the use of precision farming technology Reveals geographic variation in fertilizer consumption volume by presenting case studies for specific countries and regions, including India and Africa Discusses the pros and cons of organic vs. chemical fertilizers, innovative technologies including nuclear energy, and the U.N.’s Sustainable Development Goals Part of the Advances in Soil Sciences series, this solutions-focused volume will appeal to soil scientists, environmental scientists and agricultural engineers.

Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.
