Like timbercruiser said, food plots would work really well. Even smaller 1/2 acre plots will work great but of course that will depend on your deer population density. I like the food plots in the 1/2 to 1 acre range because the deer feel more comfortable using these plots during the day knowing they have cover close by. Irregular shaped plots are best also remember you will be shooting across these fields so don't make them too long.
