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

News & Events
We have a new decision support tool app. The Soil Agricultural Groundwater Banking Index. It can be used to identify soils best suited for on-farm groundwater recharge. You can find it on the apps page.
