Agreed, with a small plot like that, young plants won't last long. Also the idea of planting in rows, while good for a garden isn't necessary for a food plot.
Plus, don't trust that your camera captured everything that was in the plot. Game camera's are funny that way, for example just this past weekend one of our cameras took 1400 plus pictures over a two week period, most have deer in them. Yet another camera sitting over a mineral lick that looked like it got hit hard just 100 yards further away only had 18 pictures on it, most of my brother. Now we know deer were there, but the camera just didn't do it's job.
