Grundy County, Iowa | We’ve no-tilled beans into corn stalks for 25 years. Beans never grow as fast or look as pretty as tillage but too many advantages including $$ to work the ground. The problem this year appears to be the residue from 250 bushel corn last fall. And the wind. The wind piled corn stalks along fence lines and even in the field. Had a poor stand some places.
We do some cover crop and worked that in with a vertical tillage machine. That cures the residue problem. But that blows too on occasion.
We run normal knife rolls on a 612 corn head. They need replacing. We’re wondering about Calmer’s rolls or 360 chain rolls. When cut that fine does the residue blow more or less. Anyone with any experience? |

| More cut up = more blowing. |

SE Nebraska | We’ve used the Calmer rolls for a couple seasons now on a 612 and had good luck with them, they size the trash nicely, the wind last harvest piled up trash everywhere don’t think it would have mattered what size it was it all blew down the row and collected in the turn ends or from neighbors with perpendicular row directions. Couldn’t get through it with a strip till machine it just formed a blanket. |

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. |

Arkansas | We've went away from the chopping head and leaving what's left of the stalks standing. We just split the middles on 30 inch rows the next year. By not sizing the stalks they don't blow nearly as bad. |

SE South Dakota | Does anyone leave the stalks standing and plant 15” rows? How do you do it? Try to split the row planting 7.5” on each side or just take them at an angle? |

NW IN | I leave stalks standing. Plant in 15 in rows . Try to get on both sides of old row. 7000 planter, 1063 corn head with knife rolls. I did make chain guards for planter to keep row chains on. |
