The primary objective of phase 1 is to compile a body of easily accessible knowledge learned from past studies on the sources and transport (groundwater as related to surface water, conservation practices, and wind erosion) of dissolved solids to streams in rangelands around the world. This phase will be conducted by USDA staff. The Water Quality Information Center (WQIC) at the National Agricultural Library (NAL) will develop a bibliography. The primary product will be an annotated bibliography, similar to that produced by the USDA Conservation Effects Assessment Project, which is available at: http://www.nal.usda.gov/wqic/ceap/index.shtml. HTML and PDF versions will be placed on the WQIC Web site for easy access. An online dynamic version will also be developed. The dynamic version generates citations from real-time searches of the AGRICOLA database, so the bibliography is always current. Along with AGRICOLA, a number of commercial databases such as Scopus, CAB Abstracts and BIOSIS will be searched to identify relevant documents. No date limits will be applied to the searches unless the volume of relevant documents is unmanageably large. The document will be < 500 pages and search criteria will be cross-linked with NRCS conservation practices numbers where possible (i.e. prescribed grazing is 528). The primary objective of the second phase is to synthesize the body of knowledge assembled in phase 1. While the scope of the literature search is world-wide, the synthesis will focus on dissolved-solids sources and transport processes relevant in the UCRB. The cross-linking of NRCS conservation practices to impacts documented by the literature will provide a direct benefit to land management agencies by providing them with an easy lookup table of benefits by practice and associated literature references when proposing potential salt mitigation projects. This phase will be conducted by USDA staff. The primary product is a draft written analysis that will later be included in a jointly authored publication through USGS.
