You are describing zone-til, which just busts up the path the planter will drop the seed in. They do have what they call a 1-tripper, which tils, injects fertilizer, and has the planter behind that. It takes some big iron and flat fields to run that stuff effectively.
No-til is just that, no tillage. The planter cuts through the trash and drops the seed into otherwise undisturbed ground. We still have to run a ripper through it where it is run on a lot to break up the soil. Sometimes fields that used to be flood irrigated or conventional- or full-til need ripped from end to end to break them up.
