Your Local Soil
It is obvious as you look out he window of your car while driving on 395 that the Eastern Sierra is highly variable in its soils due to differences in altitude, geology, and availability of water. In many areas of the world, vast tracts exist of similar soils, but here you can find different soils on each side of the highway!
This page has links to resources to help you identify your soil type. Key things to learn about your soil are:
- Typical soil pH
- Salinity issues (usually calcium here)
- Soil texture: usually sandy loam or loamy sand, but it can vary
- Presence of an undesirable layer like clay or salt
This document has information to determine your soil's texture "by feel" using your hands. You'll need a little water and a paper towel. Soil Texture Feel Test (PDF)
The local Farm Advisor has written up a few soil fact sheets for local communuties. These are a good place to start.
One of the best tools is UC Davis' soil web map service: https://casoilresource.lawr.ucdavis.edu/gmap/
