Soil survey laboratory methods manual / Руководство по лабораторным методам исследования почвы

Laboratory data are critical to the understanding of the properties and genesis of a single pedon, as well as to the understanding of fundamental soil relationships based on many observations of a large number of soils. The development of laboratory methods, the analytical database, and the soil relationships based on those data are the cumulative effort of several generations of scientists. These efforts may be defined as methods development, database design and development, and investigations of data relationships. Methods development in the Soil Survey Laboratory results from a broad knowledge of soils, encompassing topical areas of pedology, geomorphology, micromorphology, physics, chemistry, mineralogy, biology, and field and laboratory sample collection and preparation. The following lists many of these contributing scientists, some of whom have since retired from USDA-NRCS and/or are deceased. Some of these contributions are cited throughout this manual as scientific publications. The following list is not comprehensive for developmental work preceding the formation of the Soil Survey Laboratory in Lincoln, Nebraska. In addition to the scientists, the current Soil Survey Laboratory technicians are also listed. These analysts play a key role not only in performing the analyses but also in developing new or modifying old methods, and ensuring data quality. Scientists (past and current) and physical science technicians (current) are listed alphabetically as follows <...>
