If you are relying on food plots to sustain deer, you are barking up the wrong tree.
Food plots may be more about aesthetics to hunters than benefit to wildlife.
Even in a heavy ag area, less than 50% of their daily intake is agricultural plants. Most of their daily nutrition comes from the weeds growing around the edges of the fields.
Would be an understatement to say hunters generally have been over-sold on the merits of
cultivated food plots for deer.
Having most my private deer-hunting acreage in an area with little agricultural crops, I thought
cultivated food plots would be of great value. After decades of doing this, I believe my time & money is generally better rewarded using it to manipulate native habitat, rather than planting things.
I'm not opposed to food plots, still have some. But it is amazing to watch deer walk around a lush clover plot picking out the native ragweed (yes, weeds in my plots), seeming to prefer the ragweed over the clover. Similar is seen with the honeysuckle that is now growing all over the place, in that the deer seem to spend more time eating the honeysuckle than the oat/wheat food plots.
I know many hunter-managers have gone to extreme expense & time to rid their properties of native weeds & honeysuckle, and now believe much of that has been a mistake. Johnson grass is
NOT a native weed! Round that up! And fescue is the scourge of the earth. Good weeds are "forbs" (flowering plants), not "grasses" like fescue.
Ragweed protein content typically ranges from 15% to 22% in its pre-flowering stage, making it a surprisingly potent source of crude protein that
rivals high-quality alfalfa.
And that's why habitat management - not food plots - is so critical in private land management. Through habitat management, I've seen properties transformed from an environment that will support 5-6 deer per square mile to an environment that would support 120 deer per square mile. No food plots.
Put another way, 10 acres of manipulated native habitat can often produce more year-round deer food than a 1-acre cultivated food plot. "Manipulations" include most any tasks to help more sunlight hit the ground (chainsaw is your friend), mowing, disking mowed areas, prescribed fire, reducing grasses (like johnson grass & fescue).
And, no, I'm not opposed to food plots, just saying they've been over-rated by marketers selling food-plot related products, which includes tractors, atvs, other equipment, expensive seed & other gimmicks.
