[QUOTE="Simon C, post: 3410962, member: 319"] The one thing we know for sure is that no-till reduces the losses of organic matter. If you don't keep artificially aerating the soil to depth, you won't be stimulating the bacteria that feed on it and therefore releasing CO2 into the atmosphere. The other thing is that organic matter is no use if it is down below the aerobic layer, however deep that is. Even in permanent grassland, fence stakes don't rot all the way down, they give a very good idea of how far the air is getting into the soil and so ploughing OM down below this level is pretty stupid. In the days of horse drawn ploughs running at four of five inches in mid winter when the soil was too cold for any microbial activity to be going on anyway, probably wasn't a big deal, but today's deep summer and early autumn ploughing is a whole different ball game.
