Welcome to the UC Davis Soil Resource Laboratory. Our research covers many aspects of soil science including:

  • Soil genesis and morphology
  • Rangeland soils
  • Hydropedology
  • Water quality and constructed wetlands
  • Soil-landscape relationships and modeling
  • Watershed-scale digital soil mapping and quantitative pedology
  • Repackaging soil survey into interactive decision support tools
  • Soil survey related outreach, including one of the first online soil surveys, SoilWeb
