cover crop

wanted to plant some turnips for cover crop this fall in some bean ground. we used Sonic for herbicide and now i'm finding out probably should not plant turnips as the sonic will kill it. we can do rye but some of the ground was hay ground last year and all we did was disk it. I think it's got some hard stuff below yet and I don't have a chisel or ripper, thus the reason for the turnips, or radishes.
what do you folks that plant radishes or turnips after soybeans use for herbicide on your beans? was told select max but that don't control broadleaf weeds.

I rent the farm out but this year he planted radishes after soybeans. There are two different radishes and the red ones are about 3" in diameter and white ones look to be over a foot long so far.

You are too late to plant radish now anyway if you want it to amount to something. Rye will be pretty much the only choice.

Try a few, then you will know.

Those brassicas take a lot more herbicide carryover than they 'should' many times. Your sonic would have been sprayed a long time ago, did you get a fair amount of rain this summer?

I sprayed Roundup and Status on my corn pretty late (what a rainy year...) then spun on some urea 2 weeks later and threw a sack of cover crop mix in the spinner. Just a test, not enough to really do anything.

Have softball size turnips in the cornstalks now. And some small radish. I haven't seen any of the other stuff, but then I'm not really sure what I'm looking for on those others....

If you have a real companion layer, I think these cover crops would be real slow at curing it. What they do is send their tap roots deep into soil you rip open, and that organic matter helps create a soil structure that won't compact into a hard pan in the future. They are a good maintainer, not sure they really can burrow through a hard layer any better than anything else?


If you want a deep rooted cover crop that grows through anything..... dad left me a farm infested with Canadian thistles. I tell you, I had the most mellow subsoil you could imagine! Ha.

The Radishes planted where we had soybean and the red radishes are as 4" in diameter and white are 2 1/2" inches in diameter and about 18" long with 4" sticking out of ground.

its to late plant anything now to grow, rent you a chisel plow or ripper
