Abstract

The Iowa Geological and Water Survey (IGWS) of the Iowa Department of Natural Resources (IDNR) entered into an agreement with the USGS in September of 2002 whereby the IGWS would design a database for field parameters and collect two soil sample sets. One set for the USGS to process and analyze, and one set to reposit. Field parameters included ambient site conditions, GPS location, elevation, landscape position, vegetation type, National Resources Conservation Service (NRCS) soil type, sample depth, and soil horizon, texture, color, and moisture. Digital photographs were taken of the site and samples at each location.
