What is Texture AutoLookup (TAL)?
TAL is a group of programs to determine soil
texture classes based on four major soil classification schemes:
- USDA (U.S. Dept. of Agric.)
- UK (England & Wales)
In addition, TAL for Windows now includes
seven more classification schemes, and supports custom (user-defined)
soil classification schemes.
There are four members in the TAL family:

If you wish to be informed about TAL's progress,
bug reports and fixes, why not join TAL's
mailing list? This mailing list is for users who are interested
to know when TAL's next version will be out, any problems (bugs) and
fixes. Mail traffic is intentionally kept very low (perhaps 1-2 emails
every few months).
Problems, Suggestions, Comments?
If you have questions or have trouble using
any of the TAL programs, please let me know. I would like to see TAL
programs improved further so it is even easier to use and implements
as many soil classification schemes as possible.
