This past winter we put Precision Planting's latest down force control, DeltaForce on a 16/31 John Deere 1790, only putting DeltaForce on the corn rows and leaving John Deere's standard pneumatic bags on the bean rows.

For this trial we kept the bean rows constant at 325 lbs down pressure and DeltaForce was running anywhere from 50 lbs to 450 lbs of applied down force.
