Symptoms of soil degradation are numerous and include decline of soil fertility, development of acidity, salinization, alkalization, deterioration of soil structure, accelerated wind and water erosion, loss of organic matter and biodiversity. Land degradation has been caused by excessive use of land, improper agricultural practices and deforestation which resulted in reducing amount of fertile soil. Irrigation and pesticide use can improve soil productivity . These methods target long-term use so that the soil remains fertile and productive. The soil loses its cultivating capabilities by weakening the structure and washing out the rich ingredients. 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.
