There is so much involved and with out fences, 150 acres in Texas will be tough. I would find out what will grow in your area with highest protien quality and plant as much as you can. As far as trying to control the buck quality you won't unless all the surrounding properties do the same. I wish I had 150 acres, but the real truth is its not enough to do all that you want. Give the deer something good to eat/drink and they will stay around your property for the most part. Try to get your neighbors on board to control the does. In PA we know bucks travel well over a mile pre rut, who knows how far during the rut.
