Well, due to the overwhelming attention required of the sunflower project, I have to admit the no-till project is getting a bit neglected.  But it is still proceeding nonetheless.  But it is still going without me.   I pulled off part of the tarp to take a look at the soil yesterday and most of the plants have died off.  In the control section there are some rhizomes which I suspect are from couch grass, but most everything else is dead.  These has left the soil with a nice layer of lose soil, and I have not checked, but I assume it will be much easier to dig in now.  I wil do bulk density testing as soon as I can find the time. I will be curious to see the difference.  Here is a video of the area now:
