19 acres isn't much to work with and any turkeys spending time on your property are also spending a lot of time on other's property also. With that said, one of the quickest ways to improve turkey habitat is a controlled burn. Turkeys flock into a burn practically before it stops smoking. They first come in for the parched insects and seed. Later as fresh new growth starts it promotes insect life and keeps the turkeys around. It opens the undergrowth and makes the area more attractive to them. Afterward consider some plantings for turkeys. Small grains like millet and sorgum are excellent food sources and easy and cheap to grow. Clovers and chufa are also good but take a larger investment in preparation and time.
However right now is not the time to burn. Your hens are likely nesting or have young poults that can't escape the fire right now.
I recommend you contact and talk to your local state biologist, forester and county extension agent. They likely will pay you a visit and give you good specific advise about your property.
