RE: Turkey and Deer plots
I too like clover for Turkeys.
They eat some clover - but mostly are attracted to the BUGS in the summer months. Also - clover usually grows low enough that a turkey feels comfortable in it. And in the Spring - low growing clover plots make great displaying areas for Mature toms.
As for seed bearing plants for turkeys - I've tried several - and found that corn is best for winter months with snow. Plots of Buckwheat, soybeans, cereal grains never seem to offer food at the right time - at least not in my area.
In the fall - our turkeys are looking mostly for seeds of ash, cherry, beech - also apples. No plots seem to "pull" them off the natural foods (except maybe a fresh spreading of manure - YUCK!).
