As many deer as the land can hold at it's worst. So best year good summer rain lots of AG field and food plots do great with bumper acorns so the green fields grow throughout the winter and deer have food all year is awesome. And that year you can hold a ton of deer. But what about the years of summer drought terrible crops that get cut early. No acorns and plots get flooded in December rain. Those years the deer will suffer and bucks won't reach full potential. So personally I want as many deer as the land can hold on a bad year. And on good years with more food than deer then we will have major growth. They way to check for density is to do a camera survey and have a cage in the plots. If the caged area is significantly taller than the outside you have too many deer in the area for the food available.
