If that isn't testament to his advanced age, I don't know what is. I like seeing big antlers as much as anyone, but for whatever reason, seeing a deer with the body of a Guernsy milk cow is what really gets me excited! If the 12-pt and the Incredible Bulk were both within range, at the same time, I'd probably faint from the pressure of making that kind of decision. Ironically, my wife once sat in a stand and watched a beautifully symmetrical 10-pt and an old, bruiser of an 8-pt square off and posture at one another. The 10-pt, who wasn't any older than 3.5, decided he had some seriously pressing business in the next woodlot over and quite literally high-tailed out o' there. My wife, not knowing how entranced those critters were during their "walk-up", never moved a muscle for fear of scaring them off.
Buckwheat is a dear friend of mine, because it is willing and able to grow on the absolute worst excuses for soil imaginable. When the first field of it bloomed, on my grandma's property, she excitedly informed me and dad that, "your little barleys are doing great!"
So, ever since then, dad and I plant barleys just about every year. In addition to the soil benefits (on ground hardly worthy of the moniker), buckwheat is a food plot option that has a remarkably broad appeal to wildlife.
Any more, the value of BW to deer is no more than a tertiary benefit, in my eyes. It is planted, first and foremost, for what it provides to the follow-on crop. You've got good soil there, but you are also more attentive and astute than most; I suspect you will be keenly aware of how well the next thing you plant in that area grows. Given your proclivities, I'm sure you already took note of the bees (and therefore birds) and the rabbits and the turkeys (my gosh, the turkeys!) and the various and sundry predators that have all delighted in the mixed salad of buckwheat and cereal grains. If the current crop of BW gets a chance to harden off seed, and Kentucky has a late turkey season, steel yourself for what is to come.
I have always loved seeing pictures of your place. I know, without a doubt, you and Aldo would have been the very best of friends.
