North Central Illinois | I know of a fella that uses wide sweeps on a disk ripper to kill alfalfa in an organic system. Runs over the field once with regular ripper shanks first. He does this in the fall, so as to leave residue on the surface. Then he does finish tillage in the spring.
Alfalfa sure is some tough stuff, unless you want to keep the stand another year, then it ain't very tough at all. I expect that some would survive the hinniker, but it might work. I disked the headland on a field that I fall plowed just as it was breaking dormancy in the spring (I didn't plow it with the rest of the field, because I had baleage stacked on the edge of that end). Come the 10th of May, I couldn't tell the difference between what I had disked and the good stand across the road.
I guess, try it on a small scale and let us know what happens. | |
