Nope. The idea in no till is just adding stuff to the top and letting worms and roots handle the tilling.

I've had good luck just dumping a foot or two of finished compost on the ground and growing in it.

Another solid no-till approach is sheet mulching. You put down a layer of cardboard (to kill weeds), then layers of carbon and nitrogen like straw and kitchen scraps. Wait a few months, then plant. So you could do that in the late summer or fall to prepare a site for spring planting.

A lot of these things depend on location, though. Something that works great in Pennsylvania might not work as well in Utah.
