De Witt. I was hoping there was something I was unaware of. I need to send a sample off to A&M, but it might not be for a month or two.

I have another related question. Mistake or not, I'm planting some trees from E. Texas/SE USA this fall. A couple of Pin Oaks and Hornbeams, and one Black Tupelo. I'm certain we're alkaline; so should I plant preventatively by amending the soil or symptomatically if I see excessive chlorosis? I tend to the latter, but that's why I'm here to ask. Thanks again.
