I’m a whole different situation:
I like to graze s few acres, I use turnips.
They grow a big long deep tap root, but it is a cord, not the whole carrot tube into the ground. So they make holes too, but thinner holes. Frankly in a hard pan I see both turnips and radish hitting it and turning sideways often enough, they can’t do Miracles but they do some work.
I plant my turnips with my spring small grains, they tolerate the shading and don’t grow too much until the smal grain comes off. I swath my small grains, in some years there is a fair amount of turnip leaf in the windrow that would be a concern. You can’t plant radish early, you can plant turnips early.
The turnip or radish sucks up nutrients, and then releases them as they rot away again. So best to leave them (or graze them and cycle into manure) to keep the soil building going. In my cold climate they winter kill and rot easily, tho they do tolerate a lot of cold if you are in a mild climate. Still seem easy enough to kill.
Really a lot to experiment with and see what fits your climate and timetable with these brassicas.
