Beschreibung

Soil is a fundamental resource that urgently needs to be protected and, where damaged, restored. This text gives readers a comprehensive understanding of soil conservation including its long-term benefits to agriculture and its role in terrestial ecosystems.

In view of the grave consequences of soil degradation on ecosystem functions, food security, biodiversity and human health, this book covers the extent, causes, processes and impacts of global soil degradation, and processes for improvement of degraded soils. Soil conservation measures, including soil amendments, decompaction, mulching, cover cropping, crop rotation, green manuring, contour farming, strip cropping, alley cropping, surface roughening, windbreaks, terracing, sloping agricultural land technology (SALT), dune stabilization, etc., are discussed. Particular emphasis is given to soil pollution and the methods of physical, chemical and biological remediation of polluted soils. This book will lead the reader from the basics to a comprehensive understanding of soil degradation, conservation and remediation.

The book 'give lucid accounts of the principal processes of soil degradation, its effects on soil quality, plant production and human health, and methods of improvement of degraded soils'. the book is interesting to the graduate and undergraduate students in Soil Science, Agricultural and Environmental Sciences as it provides complete aspect of soil degradation supplemented with many color plates of the real issues and a lot of self study questions at the end of each unit.

Klappentext

This book views soil as a fundamental resource that must urgently be protected, preserved and restored, in order to secure food for the ever-increasing human population and to maintain the health and quality of the Earth's ecosystems. It emphasizes the immediate and long-lasting impacts of soil degradation on agricultural productivity (crops, livestock, and fisheries), air and water quality, health of organisms, and the planet's life support-systems.

This book highlights the mutual relationships of terrestrial ecosystems with their physical environments, and stresses that when the soil is degraded, a concomitant deterioration takes place in the whole ecosystem. Throughout history, soil degradation has, in fact, played a crucial role in the collapse of many civilizations.

This book comprehensively describes soil degradation in terms of:

· Causes: deforestation, vegetation over-exploitation, shifting cultivation, overgrazing, unbalanced fertilizer use, over-extraction of ground water, etc.

· Processes: soil compaction, surface crusting, soil-fertility depletion, water erosion, wind erosion, salinization, soil pollution, etc.

· Conservation and Remediation Measures: soil amendments, decompaction, mulching, cover cropping, crop rotation, green manuring, contour farming, strip cropping, alley cropping, surface roughening, windbreaks, terracing, sloping agricultural land technology (SALT), dune stabilization, etc.

Numerous examples, figures and tables enhance the presentation, leading the reader from the basics to a comprehensive understanding of soil degradation, conservation and remediation. Study questions at the end of each chapter help to reinforce concepts.

While the text will be of particular interest to undergraduate students in grasping the fundamentals of soil science, it will also be of interest to graduate students and those in agricultural, biological and environmental sciences who study soil and its sustainable management. Professionals, including agronomists, horticulturists, foresters and landscape specialists, will find it of interest, as well.
