Vegetables, fruits, and grains are a major source of vital nutrients, but centuries of intensive agriculture have depleted our soils to historic lows. As a result, the broccoli you consume today may have less than half of the vitamins and minerals that the equivalent serving would have contained a hundred years ago. This is a matter for serious concern, since poor nutrition has been linked to myriad health problems including cancer, heart disease, obesity, high blood pressure, and diabetes. For optimum health we must increase the nutrient density of our foods to the levels enjoyed by...

Nearly two billion people depend on hundreds of millions of smallholder farmers for food security. Yet, these farmers lives also hang in the balance due to their extreme vulnerability to the risks of soil degradation and depletion, soil exhaustion, climate change, and numerous biotic and abiotic stresses. Soil Management of Smallholder Agriculture explores the potential smallholder agriculture hold for advancing global food security and outlines the challenges to achieving this goal.

The book addresses the challenges and opportunities that resource-poor and small landholders...

Many wetlands around the world act as sinks for pollutants, in particular for trace elements. In comparison to terrestrial environments, wetlands are still far less studied. A collaborative effort among world experts, this book brings the current knowledge concerning trace elements in temporary waterlogged soils and sediments together. It discusses factors controlling the dynamics and release kinetics of trace elements and their underlying biogeochemical processes. It also discusses current technologies for remediating sites contaminated with trace metals, and the role of bioavailability...

Soil and Environmental Chemistry, Second Edition, presents key aspects of soil chemistry in environmental science, including dose responses, risk characterization, and practical applications of calculations using spreadsheets. The book offers a holistic, practical approach to the application of environmental chemistry to soil science and is designed to equip the reader with the chemistry knowledge and problem-solving skills necessary to validate and interpret data.

This updated edition features significantly revised chapters, averaging almost a 50% revision overall, including...

This book is about applications of remote sensing techniques in the studies on soils. In pursuance of the objective, the book initially provides an introduction to various elements and concepts of remote sensing, and associated technologies, namely Geographic Information System (GIS), Global Positioning System (GPS) in chapter-1. An overview of the sensors used to collect remote sensing data and important Earth observation missions is provided in chapter-2. The processing of satellite digital data (geometric and radiometric corrections, feature reduction, digital data fusion, image...
