Humboldt IA | Last year was our first harvest with the Calmer BT chopper rolls (on a Case IH head FWIW). I don't think our residue blew as bad as it had in years past, and definitely blew less than neighbors with chopping heads. Any of the leaves that end up going down through the rolls get cut up into little pieces, just like the stalks. The small pieces of leaves then get mixed in/settle in with the stalk pieces and then the wind doesn't seem to pick them up and put them in the fence/ditch. And with the 10-12" of stalk still sticking up out of the ground, it helps keep that layer of finely cut residue in place.
We then disk rip the stalks so can't comment about planting directly to that residue.
And now with all the rain we've been having, I think those small pieces of stalk don't plug up the intake guards as easily as they used to...they get sucked in and hopefully go all the way through the system. | |
