borealboy; Clover will feed the deer from the time it greens up to late fall. Apples will only draw the deer for a few weeks in the fall until they' re consumed. In your area the deer winter feed on browse (cedar, balsam, dogwood) but there are farms growing rye, wheat, alfalfa and clover. An area 30 x 100 yds has the potential to produce large amounts of hay (ton(s)). An other thing you could do is create a larger opening (4-5 acres) and let it regrow in brambles and poplar. These clearings keep the browse within reach of the deer.
