Ag Web has an article from a long time no-till farmer which should please the greens and foodies on first reading, if not the second.
I say that because he makes clear it's not an open-and-shut case for no-till, it's heavily dependent on the type of soil and the nature of the topography. And an investment in tiling is required. (My guess is plowed land dries more than no-till land, hence the need for tile.) And he's very much into new technology. So the overall perspective is very different than the romanticism I see in many locavore-organic-sustainable ag types.
