The USDA Web Soil Survey site is not secure and it looks like they have an app and a lot of the soil health info is on this site.

Luckily, soil maps are easy to access, whether through the USDA Web Soil Survey, or books from your local extension office.

Gravelly, well-drained soil is ideal in grape production, because grapevine roots do not want to be submerged in water. On the flip side, too-well-drained soil can create an issue with nutrition, as in, the soil organic matter might be too low to sustain wine grape production.

Soil maps can also provide and excellent base for your vineyard maps. If there are two different soil types at your site, consider planting one block of vines to each soil type, IF this is also practical. Nutrient management will be much easier once you are aware of possible drainage or nutrient differences.
Finally, when you submit soil samples, you will need to enter the soil type on the form for the soil tests and for more appropriate recommendations.
