Add another app to your Ag Apps folder on your smartphone. It’s free for both iPhone and Android users. The app, SoilWeb, combines online soil survey information with the GPS capabilities of smartphones.

The SoilWeb app is a portable version of the UC Davis California Soil Resource Lab’s Web-based interface to digital soil survey data from USDA’s Natural Resources Conservation Service (NRCS). Because the app provides soil survey information in a mobile form, it is particularly useful for those working in the field.

Until recently, a disadvantage of Web-based soil survey formats was that user access was limited to desktop computers with an internet connection. That’s one reason that NRCS soil scientist Dr. Dylan Beaudette, while still a graduate student at UC Davis, developed the SoilWeb app in collaboration with NRCS and the UC Davis California Soil Resource Lab.

SoilWeb can retrieve a graphic summary of soil types in response to a user inquiry in the form of soil profile sketches. Each profile sketch shows soil horizons, often compared to a vertical ice cream sandwich made up of layers of soil. Soil names, locations and taxonomic categories are also shown.
