I've seeded about 15 acres in sunflowers and millet. Deer eat both but in the center of all the alfalfa, oats, corn and beans I hope they'll not bother my plots. The last thing needed around here is more deer, even with the winter die-off the deer outnumber all other wildlife. (well seems that way)
My planting method
Run Vic through to make sure there are no nests
cultivate through the standing grass and other wild vegetation.
Broadcast sunflower and millet seeds
cross rake or drag to cover most of the seeds.
sunflowers and millet grow up through all the existing vegetation (there is a lot of seeds on weeds too)
Other areas come August as the burning nettles die back (wildlife feeds on those extensively)
nettle areas are cultivated and planted with Rye.
Rye is green like a golf course and all winter turkeys and yes those dang deer scratch and feed until the snow is too deep. Then they move to the "seed" fields, millet and sunflowers are above the snow. While all ag fields are covered and inaccessible too.
All summer I edit or weed the roost trees. Ironwood, elm and box elder grows up in between the branches of large oak trees. Cutting these out improves roosting areas.
I decided on seeds mainly to help pheasants, quail and dove. Until winter turkeys are not usually too interested in food plots. All kinds of other things are available for them to eat, like insects, acorns, basswood and ash seeds, to name just a few.
Every area, region and zone is different. What else are others doing?
If you agree with me call it fact; if you disagree - call it my opinion.
After all - we are talking turkey.
