I recevd a tremendous number of responses on soil testing advice.
Next week I'll be calling UC Davis and see what they have to offer.
I'll post the results when they are in since so many did respond, with
only one negative response that this should not be on the endurance
list. Thanks to all who did respond.
Good luck to all riding this weekend! I'm heading for Mendocino
tomorrow (Friday).
