Just youtube Ray the soil guy. Hard to beat his descriptions. Now for the good Doctor. I think the problem that everyone, including myself that does any no till planting, is accepting what, and to quote him, a "perfect plot" might be. Will it be a monoculture or only the plants from the seeds you have planted?? Probably not. Will the deer give a damn?? Pretty sure they won't since they survived quite well for millions of years on just Mother Natures throw and mow technique. If he were to explain the different techniques, I would get his comments, but to just across the board and say that one is wasting their time, well he has someone padding his pockets is my call.
I have no problem if one chooses tillage, but there are multiple ways to hunt a deer, and there are multiple ways to plant a plot, no right to say what is a waste if it works. Sure are a lot of big time farmers making bunch more money then he, in my area that are on the wagon of no till and always a cover crop. Go figure, guess they don't know of this Dr Kroll.
