Wet fall disking, chisel plowing

Any issues with fall disking when it is so wet like this? Will I make more problems as you would disking in a wet spring, or will the freeze/thaw corrct some smear issues from the disk. Also, any problems that can be caused by disc chiseling moist to wet ground. Have a few feilds thqat NEED to be broke up down in that 8"-12" depth that had terrible hard pan this year. Pretty sure with all the rain we have had I will not get that fall dry hard pan shatter I was hoping for, but, it needs to be hit, and mixed a bit with the lime and organic matter(manure, stalks).
 
The top disking when wet will not hurt anything. The freezing and thawing will take care of that.

The deep tillage wet is a different story. The deep shank will just cut a slot and smear the sidewall. So you do not get rid of the hard pan and the smeared side wall creates a horizontal root block for the next season. The corn roots just go down the slot and do not spread out like they need too.

So I would not do the deep tillage when wet. You may actually hurt the yield potential of the filed.
 
Being a no-tiller,I'd say a disc will hurt yields anytime except when the dirt is bone dry 5 or 6 inches down.Maybe real sandy soil might not get hurt by discing . A disc will leave a compacted zone especially when wet that doesn't go away easily.
 
Disks scare me any more, but I am on clay, much clay, here. Wouldn't be a problem in loam or sandy loam I'm sure.

Wife was using the soil saver yesterday, left some good tracks in the bean field and it is uneven field.

Besides, we wanted to find some more rocks.......

Would like to move to no till on about 40% of my acres, but so far have had poor luck with it. Roots just did not penetrate the soils. Gonna try no tilling again, but into rye cover crops
 
Disking will do nothing to change the hard pan for better or worse. Disking when wet will create close. Chisel plowing when it is dry will help to break up the hard pan. Doing so when it is wet will further build up the hard pan. It seems like a darned if you do darned if you don"t. I would chisel plow this fall. My reasoning being doing so you will open up cracks that will help the field drain in the spring. Hopefully the cracks will fill with moisture and break up the soil with the freezing and thawing. There is no benefit to discing the field think fall.
 
The worst primary tillage job we do in the fall on our clay soils is still better than the best job we can do in the spring. I wouldn"t let it sit over winter.
 
It's hard for people not from here to understand this. If we don't get it fall plowed, no matter how wet it is, it will hurt yields next year. Spring plowing is always a disaster.
 
Those of us in the cold, wet north getcha! Winter does a great job breaking down any clods. The deep ripping stuff I don't know about, I understand you want to do that in drier weather. But if it's dry down in the compacted zone I'd think that would work. If you get a freeze 2-4 feet deep like we do in an open winter it should do a lot of the work for you.
 
Agree down here in Houston Black Clay. If clay is dry or dry enough to not make a rut fine, be it a rolling disc, chisel, or field renovator/ripper. If it makes a rut, too wet. Course at the end of the summer season it can be too dry too, but that can be broken up and pulverized, just need to slow down, take it easy, and give the implement time to work.

Agree a dose of rain and especially a freezing spell will quell the best of the clods.
