Re: Help! Help! Help

Laboratory data, including particle-size distribution, are available on a large number of soils at this web site:

The easiest way to access the data is to select from the menus:
1. ""Soil Information and Data;
2. National Soil Characterization Data
3. Area by State and County
4. ""HELP""
5. Select State or ""Foreign Nation""

The particle-size data is part of the ""Characterization data.
