Soil Amendments and Environmental QualityJack E. Rechcigl CRC Press, 25 set 1995 - 528 pagine This book presents a comprehensive and balanced overview of soil amendments and their effect on the environment. It encompasses both positive and negative aspects of chemical fertilizers that supply nitrogen, phosphorous, sulfur, lime, micronutrients, and trace metals. Pros and cons are discussed with respect to the optimal and the most environmentally sound use of soil amendments, and guidance is provided on how to minimize the environmental effects of amendments. Natural fertilizers, including manure, sludge, fly ash, phosphogypsum, and byproduct gypsum are also discussed. Alternative agronomic practices and biotechnology that ameliorate or minimize potential adverse effects of fertilizer use are examined in detail. This authoritative and up-to-date treatise is multidisciplinary in nature and international in scope, a powerful reference tool for researchers, a thorough guide for practitioners and policy makers, and an excellent text book for academic courses. |
