GPS based, real-time access to USDA-NRCS soil survey data, formatted for the iPhone. This application retrieves graphical summaries of soil types associated with the iPhone's current geographic location, based on a user defined horizontal precision. Sketches of soil profiles are linked to their official soil series description (OSD) page. Soil series names are linked to their associated page within the CA Soil Resource Lab's online soil survey, SoilWeb [1]. An up-to-date map of were data is available for queries can be found here [http://casoilresource.lawr.ucdavis.edu/soil_web/national_status_map.php].

Link Issues


This is a great app that our entire team is using to find soil types but the OSD link does not work. This is really discouraging as it costs us extra time to copy and paste the link and retrieve the information through extra steps. Could you please check this out and fix the link if possible. We are trying to get our entire agronomy group and sales reps to use this information and when it doesn't work properly they choose to skip the information or make a guess at it. Thanks

When will you update????

Support ESD's

I work in natural resources developing ESD’s and used the websoil app all the time. It’s was an exceptionally useful tool. Unfortunately the last iso update on my iPhone is no longer compatible with websoil.
When will it be updated to a compatible version. The loss of your app is very unfortunate. Who can I contact to urge continuing support for this soil app.

Please Update!


I used this app frequently as a geoscience undergrad on field trips, and I know my soil science prof did as well because he encouraged everyone to download it. With iOS 11, unfortunately, it is no longer accessible, and I fear that students, researchers, farmers, and the curious public are now without a wonderful in-field utility and overall fantastic resource.

Please update this, developers!
