Burton - 5/5/2016 09:11 Never done much investigating or seemed to have issues with compaction except on a new farm i picked up last year. Has sandy nobs and loamy dips, in the lower spots corn dodnt do much because water sat, and when i combined it i could drive through standing water and only sink in 4 inches, only ran 115 bu/a. I did some investigating today and I can jump on the shovel and only goes in about 5 inches (160lbs), top 10 in is a clay loam then goes to hard red clay i dug down 28 inches and there i can jump on the shovel and get it in 3 inches. How big of a problem do i have? I plan on putting cal sol down this spring it is going to beans this year can i make it to fall then inline rip it? Will it help or hurt to chisel plow it? Shooting for 40-45 bu beans located in WC WI. Thanks in advance

Tillage never solves a compaction problem for any length of time.  A few big rains and it all melts back together, and you still have all the compaction from before, plus what occurred with the tillage in an attempt to alleviate it.  As some would say, tillage begets tillage.



Your the agronomist, I'm not. But what I've seen is a good crop usually brings about more good crops. I not sure what kind of ground you guys farm, but here, if you have a compaction problem you will go broke trying to "no till" it away.

My advice to OP is if you can get in there in good conditions chisel plow it and imediatley run a cultivator over it to get it smoothed out. The last thing you want is that clay drying out and turning to rocks, if you cant do that then just deal with it this year. That will be your band-aid fix for this year. This fall run a ripper over it and rip it up. Try to stay off it when wet and hope it starts producing better. It takes roots and OM to build soil structure and reduce compaction, but If u dot get rid of the compaction with tillage your crops will continue to suffer and you will never get the roots and OM of a good crop.
