The National Wild Turkey Federation is a great place to start.

Here is a primer on the Eastern Turkey, the subspecies you will be hunting in New York.

Turkeys need plenty of woods, but can be found during the day strutting and dusting in open fields. Look to ag fields bordered by wood lots- freshly plowed fields provide areas to strut, dust, and feed.
Toms (male turkeys) on the roost will gobble at almost anything. It is common for hunters to use "locator calls" in the evening to find turkeys that have flown up to roost for the night. Crow calls, turkey calls, coyote calls, car doors slamming, a tom will "shock gobble" to most all of them. As they have flown up for the night, if you find a gobbler on a roost, you know where to find him in the morning.
a far as turkey callsgo, start with a "box call" as they are the easiest to get a good sound from. Start calling shortly after sun up and if you are in a good area you should shortly hear a gobble from an amorous tom. Once you get that gobble, shut up for a bit as he is probably on the way. Find a bit tree to sit in front of- large enough that you are not silhouetted- so the gobbler can't get a good look at you, and so some idiot hunter doesn't shoot you in the back.
My experience hunting in New York says that fence lines don't mean a whole lot and while you may be hunting on your land, there is no guarantee that you are the only one hunting it. Remember that you are calling to a bird to bring it into range. Never call on the move (it is illegal in some states) as some hunter may mistake you for a turkey. Also, never assume that turkey on the other side of a bush is in fact a turkey- it could be that idiot hunter drawing a bead on you.
Turkey vision is excellent and slight movement or the flash of a metal buckle or anything out of place will send an old tom in the other direction surprisingly quickly. Turkeys are fleet of foot and powerful flyers- though they lack stamina.
One last thing, when you get your bird on the ground, take plenty of pictures and post them here!!
