k... My hands on experiences gardening in TX was pretty much limited to the Dallas area and east to the Sabine...
Temple and Gause look real close to each other on the map... but... there are A number of widely different soils just in the city of Macon... so... that you are seeing some difference makes sense... so...
maybe you could explain the difference between caliche and limestone?
Glad to hear that Gause, at least... is like my house...
Edit... Maybe not so close... 5 towns in between...
