When you till the soil, your giving one type of bacteria an upper hand over another. When this balance gets tipped in one direction it causes co2 to be discharged into the air, this is not good. If you have earth worms you most likely have night crawlers. These worms burrow up to 6 feet down, and break up soil just fine. These worms are really top feeders, coming out at night looking for manure and other organic material to eat. for proof lay a large piece of cardboard over your garden area and in a month you will see all kinds of worm activity under it.
The key to good organic gardening/farming is lots of compost material covering the soil. If you want to try a no till method, put a large piece of cardboard on the area you choose. Then get lots of leaves weeds and grass clippings covering it. If you got a friend with some composted horse manure mix it in, add some water and mix thoroughly. If you added green material you can't plant into it until it's done heating.
If you used only brown or dried material you can plant into it within a week or two. One way to do this is get some potting soil and create a furrow then cover furrow with potting soil. Then just add seeds in that furrow. You just suppressed all weed problems and have a great start on a no till garden.
Some start their no till by till only once to get organic material into the soil which will work just fine. But you do destroy all the burrows created by the night crawlers, and they won't be helping your veges grow right away.
Here is website that argues both sides, but I do support the no till without chemicals.
This year I will try colored plastic to cover the soil, then cut small holes into it where I to plant. Blue plastic for cucumbers and melons, red for tomatoes and peppers, and green for the rest. For watering I am going to use drip irrigation under the plastic. The major problem is cleanup in the fall, a major problem. I want to plant a cover crop in fall to feed my flock of 50+ sheep in the garden. I understand that the different colors can increase yield up to 4X.
