You did not mention how much acreage, but it sounds pretty big. I'd look now and see if I could find some heavy trails leading to the field edges. Then, starting in late summer, I'd try to set up just to glass and see if I could find some places where deer seem to "appear".
I hunt a very similar area in Kentucky. It's about 250 acres, about half of which is swamp (depending on how wet a year it is) and the other half is a buffer of land surrounding the swampy area. This entire area is surrounded by about 1,000 +/- acres of soybeans and corn, making it a great sanctuary for the deer in that area as there are not a lot of big woodlots, outside "our" swamp.
Find trails adjacent to the swamp and then leading to the crop fields. I way prefer to shoot in the woods, prior to the deer entering the fields personally as I see way many more bucks that way. Most mature bucks, in my experience, seem to prefer to stage up back in the woods for a bit, until near dark or full dark before entering the fields themselves.
Of course, when the rut is on, it's another thing and you may see bucks running across bare, harvested fields at noon time too....
