Thousands of years of poor farming and ranching practices--and, especially, modern industrial agriculture--have led to the loss of up to 80 percent of carbon from the world's soils. That carbon is now floating in the atmosphere, and even if we stopped using fossil fuels today, it would continue warming the planet. In The Soil Will Save Us, journalist and bestselling author Kristin Ohlson makes an elegantly argued, passionate case for "our great green hope"--a way in which we can not only heal the land but also turn atmospheric carbon into beneficial soil carbon--and potentially...

Digital Terrain Analysis in Soil Science and Geology provides soil scientists and geologists with an integrated view of the principles and methods of digital terrain analysis. Its attention to first principles and focus on error analysis makes it a useful resource for scientists to uncover the method applications particular to their needs. Digital Terrain Analysis in Soil Science and Geology covers a wide range of applications in the context of multi-scale problems of soil science and geology.

The industrial synthesis of ammonia from nitrogen and hydrogen has been of greater fundamental importance to the modern world than the invention of the airplane, nuclear energy, space flight, or television. The expansion of the world's population from 1.6 billion people in 1900 to today's six billion would not have been possible without the synthesis of ammonia.

In Enriching the Earth, Vaclav Smil begins with a discussion of nitrogen's unique status in the biosphere, its role in crop production, and traditional means of supplying the nutrient. He then looks at various attempts...

Features of the third edition of this internationally recognised textbook include:

• New material on gully erosion, tillage practices, erosion risk assessment, use of erosion models, incentives for farmers and land users, and community approaches to erosion control
  
• Updated sections on the mechanics of...

As soil and crop management procedures have become more complex, County Agricultural Agents, farm advisors, consultants, and fertilizer and chemical dealers have had to specialize in some aspect of soil fertility and crop nutrition management procedures, limiting their ability to provide a range of advice and services. Most farmers and growers can no longer turn to just one source for the information and instruction needed to achieve their production goals.

With over 70 percent new material, the second edition of the Plant Nutrition and Soil Fertility Manual...

Dave Elton has done it again

Exploding soils... Retaining walls made of paper... Gravity defying sand

Grounded Amazing Classroom Demonstrations in Soil Mechanics presents 35 serious but entertaining experiments that teach the fundamentals of soil mechanics to budding scientists and engineering students in an exciting and novel way. In this sequel to the popular Soils Magic, Elton has assembled a wealth of fascinating new experiments to illustrate the dynamics of how soils behave and how they can be manipulated.

Topics include: slaking, pile...

Recent developments clearly indicate that speciation studies in biological and environmental matrices are much more important than the total element determination due to the tremendous difference in bioavailability and toxicity of various chemical forms of a particular element. Different separation-detection techniques and hyphenated systems each with its own advantages and disadvantages with respect to precision, sensitivity and detection limit have been developed for the identification and quantification of the species present in systems at ultra-trace levels. This book aims to evaluate...

This compilation of techniques, methodologies and scientific data arises from a four-year Italian research project, which took place at university research stations in Turin, Piacenza, Naples and Potenza. Soil Organic Matter (SOM) represents an active and essential pool of the total organic carbon on the planet. Consequently, even small changes in this SOM carbon pool may have a significant impact on the concentration of atmospheric CO₂. Recent new understanding of the chemical nature of SOM indicates that innovative and sustainable technologies may be applied to...

The soil is being contaminated continuously by a large number of pollutants. Among them, heavy metals are an exclusive group of toxicants because they are stable and difficult to disseminate into non-toxic forms. The ever-increasing concentrations of such pollutants in the soil are considered serious threats toward everyone's health and the environment. Many techniques are used to clean, eliminate, obliterate or sequester these hazardous pollutants from the soil. However, these techniques can be costly, labor intensive, and often disquieting.

Phytoremediation is a simple, cost...
