It could be that you got some germination, but your lack of rain after that is the contributing factor.?. You didn't spray and none of the vegetation that was there at mowing, has any regrowth to it. Your original post says that it had been dry when you attempted this and you only got 1.5" of rain. It doesn't take long for dry soil to dry back out on 1.5" of rain if there is heat/sunshine involved. I have seen seeds pop out of the ground, get a couple inches tall and wildlife come through and wipe it out. Especially on plots about the size of what you tried this in. The first couple of times at my lease this happened and we thought nothing was growing. We have a lease member that traveled for his job and he got to stopping in and taking pictures of the plots when he was up there. We got pics of great looking growth in all of the plots for the first couple of sets of pictures(about 3 weeks from initial planting), then we go up there to work and see how the plots are doing, it is bare soil again. It will leave you scratching your head and wondering what you did wrong. This will really confuse you if you have a trail cam up and it doesn't produce but a couple pics of deer, only to find out that the trail cam had been messing up.
How are your soil samples for this plot or are you trying to get started on building OM? This still requires some lime and a soil test is preferred. What did you plant, I might have missed it? How many turkeys are in your area? I've seen hogs eat just about anything, but it is very rare that they don't go through and root up the soil in a few places while they are eating. Is that rooting in the latest photo or just where the duff has been flipped up? I'm just trying to help you out by asking questions here, that may let someone help you figure out what might have went wrong and possibly make suggestions to fix it.
