| Everyone is trying to figure out why it didn't work. They are not working from an impartial position. They are working from the assumption that cover crops increase yields. Start at 0, assuming nothing and go from there. Your new assumption would be that cover crops decrease yields. Keep doing your trials until you see definitive evidence otherwise. Then they have to increase yields to a point of economic return. There's some cover crop work going on here, but I'm a skeptic so far. Even if they work, do the rewards outweigh the risks?
We have some calcerous, low organic matter soils that I would like to see cover crops work to add OM and improve soil tilth. Time will tell. | |

Cover crop yield data. OOPS, what happened? Part II.
