No-till gardening: soliciting advice
I'm new to the forum. I've been organic gardening for about 6 years. I've wanted to do the no-till method (http://eartheasy.com/blog/2009/01/no-till-gardening/) for many years, but have yet to build up the nerve. I did a search of this forum but only really saw a thread on no-till as it relates to carbon emissions. Can anyone offer their personal experiences with this method? I mulch heavily every year, so at this point my bed should have a pretty good percentage of organic matter.
Still, some of my concerns:
1. lack of sufficient aeration for tall plants and good yields. Can anyone compare and contrast the difference here between no-till and conventional methods?
2. Amount of mulch used. Exactly how much are we talking and what should I anticipate in terms of additional expense?
3. Proponents of the double-dig method (which I normally do) sell the benefits of turning the soil to make nutrients deeper in the soil more available to the plants. Will no-till require a higher than normal soil amendments to achieve the same results?
4. Other differences I'm not thinking of?
I consider this a big step. If I do it wrong, I lose a lot of veggies that go to feed my family all year long. Any advice would be greatly appreciated.
