 |  موضوع: Standard Soil Methods for Long-Term Ecological Research  السبت سبتمبر 17, 2011 6:11 pm | |
|  Standard Soil Methods for Long-Term Ecological Research By G. Philip Robertson, David C. Coleman, Caroline S. Bledsoe, Phillip SollinsPublisher: O U P 1999 | 480 Pages | ISBN: 0195120833 | PDF | 26 MB
Standardized methods and measurements are crucial for ecological research, particularly in long-term ecological studies where the projects are by nature collaborative and where it can be difficult to distinguish signs of environmental change from the effects of differing methodologies. This second volume in the Long-Term Ecological Research (LTER) Network Series addresses these issues directly by providing a comprehensive standardized set of protocols for measuring soil properties. The goal of the volume is to facilitate cross-site synthesis and evaluation of ecosystem processes. Chapters cover methods for studying physical and chemical properties of soils, soil biological properties, and soil organisms, and they include work from many leaders in the field. The book is the first broadly based compendium of standardized soil measurement methods and will be an invaluable resource for ecologists, agronomists, and soil scientists.
