Agronomically Speaking

Central Iowa SureForce Trial

  • Year:  2020
  • Trial Location:  Central Iowa

Trial Purpose/What We Were Testing For: SureForce vs simulated OEM downforce 3 treatment. Manual (200 lbs) vs Medium vs Heavy

Outlying Factors:

  • Drought


  • No yield advantage, possibly due to dry conditions and RID type gauge wheels. This trend exists across all 2020 trials on Case planters with RID gauge wheels.

Bushel Advantage: +1 bu advantage vs simulated OEM down force.
