Down in Granbury, you will most likely need to add organic matter. Soil in that area has lots of mineral content, but not a lot of organic content, if it is like the soil in Cresson. I've (unintentionally) tilled up some soil at Motorsports Ranch, and it looks pretty weak on organic matter.
Take a soil sample to your county agricultural extension office, and they will do an analysis on it, ant tell you exactly what you need.
