> you'll suffer lower yields for a few years after you stop tilling, while the soil builds up a proper layer of decomposing matter on top.
Anecdotal, but can confirm, I observed lower yields (sometimes minimal, in the range of 5-10%) for a year or two after starting to till. But it's so much worth in the long run. Granted, I'm talking about the market-garden size yield. Could be different in multi-hectare yields, but I can see the difference on my scale. After the initial one or two years I can see increased yields with lowered herbicide use and less frequent weeding activity.
