I did a home test, mainly because a thorough set of soil tests at A&M would be around $80 and I decided I'd rather use it towards gardening (herbs, pots, tools, drip irrigation, etc).

I dug deep an pulled out a clean chunk of clay, dried it, grated it into a powder and tested ph, nitrogen, phosphorous and potassium. Ph was just slightly alkaline, nitrogen poor (I expected that), phosphorous poor, but potassium was very high.

Before I amend it with anything I'll be testing the topsoil. But if the topsoil is also alkaline I'll water down a little vinegar and hand water to get the ph down a teeny bit.
