Basically I'm not using man-made chemical fertilizer or chemical pest control anymore. I used to use MG fertilizer and poisonous pest control and have switched to composted cow manure and letting the bugs run their course. Other than squash bugs, I've never had to fight bugs too much anyway.
Next year, I'm planning to no-till. Unless you call a light hoeing now and then tilling. I'll cut the plants off at the ground and leave the roots to break down over the winter. Amend with a topdress of composted manure and mulch next year and let the soil biology do the rest! With a good mulch cover I'll even be able to do away with the hoe and go with hand weeding once in a while, adding the pulled weeds to the mulch.
I can't say that I've had too many extra problems with the transition so far. The biggest problem has been the extreme heat this year but that's not related to switching from conventional to a more natural form of gardening.
I've started a compost pile, it's struggling so far. I don't have a lot of material to put on the pile at this time. I've been pulling pig weed and dumping left-overs from canning onto the pile so far. With a buffalo grass yard I don't get grass clippings to compost so I'm improvising at this point. I'd like to get away from reliance on any boughten materials for the garden above seed and plants.
I'm searching for a source for alfalfa hay and wheat straw for the time being to add to the compost.
At any rate, I hope I answered some of the questions posed in another thread.
