The SoilWeb for iOS application accesses soil survey information (the SSURGO dataset, published by the USDA Natural Resources Conservation Service) at your current location.

This app was designed to be a lightweight version of the SoilWeb GMap web application. SoilWeb GMap features an interactive map for viewing and querying individual map units, while this app does not. However, SoilWeb for iOS conveniently provides a link to the SoilWeb GMap web app.

SoilWeb GMap is available at

More information about SSURGO is available at

Features of SoilWeb for iOS include:

- Soil profile sketches, estimated proportions, and geomorphic position of soil components associated with the SSURGO "map unit" identified at your current location.

- Map unit aggregate data such as estimated water holding capacity.

- Soil survey area scale and publication date.

- Component details: soil taxonomy, soil property depth profiles, land classification ratings, hydraulic and erosion ratings, forest productivity, soil suitability ratings.

- Links to Official Series Descriptions (OSDs) generated automatically.

- Component links to related web apps: Series Extent Explorer (SEE) and Soil Data Explorer (SDE).

- Link to the SoilWeb GMap web application at your current location.

- Location accuracy setting allows you to select between standard accuracy (less accurate, uses less battery power) and high accuracy (more accurate, but may use more battery power).

- Location auto-refresh feature allows you to continually look up soil data at a specified time interval.

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????

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!
