Seventy-One years of soil change in the U.S. Great Plains: insights from the Haas soil archive. Meeting Abstract. 1. Interpretive Summary: Technical Abstract: In the U.S. Great Plains, climatic and edaphic factors frequently relegate detection of soil change to decadal timescales, requiring long-term evaluation sites and associated soil archives for insight into trends in soil condition that manifest at scales relevant to sustainability. However, few multi-decadal investigations into soil change have been conducted in the region. Here, we document effects of rainfed agricultural practices on a suite of soil properties using matched historic (1947) and contemporary (2018) soil samples from the Haas Soil Archive, collected at the same locations in the northern (Moccasin, MT), central (Akron, CO), and southern (Big Spring, TX) Great Plains. Historic samples were initially analyzed by the Missouri Basin Survey Laboratory (Mandan, ND; 1949-1956) in support of activities carried out by the National Cooperative Soil Survey. Shared results will leverage knowledge and experience of a diverse investigative team using current analytical methods, with emphasis on elemental composition, soil carbon, labile organic matter, particle-size distribution, and molecular markers of antibiotic resistance. |
