RE: Corn seeds, what to use.
1 acre - even as a block is too small for a corn plot - unless your deer population is extremley low.
We suggest that for corn to do well - in cross pollination - it should be at least a 2 acre plot. You can probably get by with smaller - but not much. Then if the corn does make it to maturatity - the coon, birds, and especially squirrells will strip a 1 acre woodland corn plot - before your hunting season ever starts.
I don't want to discourage anyone considering food plots - but seriously - you would probably be better served with a sound clover plot, or perhaps one of the newer brassica type plots.
If you can plant a solid 2 acre block - say in the corner of a large field - then I'd say go for it - otherwise - I think other plots would serve you better.
