Crops to Reduce Compaction

I have a paddock that I bale grazed on during a wet spring. It is really compacted, so I fall plowed it and then planted a cover crop mix this spring that included tillage radish. The radishes go down to the plow pan and then send several smaller roots to the side.

Are there a better plants than radishes to break through compaction ?

If I remember correctly, annual ryegrass is very good for compaction.

I heard the same thing, and planted it on my last years sacrafice area. We'll see.
 
I agree with all the above. Probably I would get it in a perennial grass like OG or fescue or both and let it rest a year or most of the year and maybe rip it with a subsoiler.

Did a search on annual rye. Sounds like it does work to reduce compaction - - but one post pointed out that multiple years are needed to equal a ripper.
They spends a lot of time talking about how to kill it... Why not just graze it ?

Annual ryegrass is promoted heavily by the ryegrass producers as a cover crop for corn and beans, etc. I used to use it a lot for a cover crop after tobacco, back in the day.
It can be tough to kill out especially if you use a lot of ammonia nitrate...AN on rygrass is sort of like throwing gas on a fire. It lovesss nitrogen.
It doesn't like a lot of competition from other established grasses so it will eventually decline.
 
We have wild radish here and it certainly grows well, we also have a lot of compaction from the previous owner (25 years ago) who had Percheron horses that totally overgrazed the place, and always followed the irrigation line.
We have a good 3 bottom subsoiler that takes everything a 100HP tractor has to pull, especially if there's sod. In my less rocky fields I try and do a pass with every plowing, and there are still spots I can't get right yet.
