The recent dry conditions across the state, carried through from the 2020 growing season, has created an environment in which field fires are of concern this spring if current conditions continue to persist. Strong winds can increase problems by acting as a catalyst, drying crop residue,...
The unprecedented August 10 derecho storm event has caused significant damage to Iowa corn fields. If it’s decided to proceed with harvesting the field for grain, several operational changes may increase performance and productivity of the combine.
It’s always difficult to forecast weather, but if dry field conditions persist, potential for combine and field fires this fall could be a problem. All it takes is a single high-temperature source in the engine area, or an overheated bearing to ignite dry plant material.
During harvest...
Increasing sprayer travel speed causes the controller to increase boom pressure (and decrease droplet size). If field conditions have you running behind and your sprayer travel speed has increased 20–25%, consider using one size larger nozzle tip to minimize drift potential.
Accelerated, early planting in some parts of the state increases pressure on applicators of preemergence herbicide to speed up sprayers to cover a larger numbers of acres. Increased speeds increase boom pressure for existing nozzles, and can tempt applicators to increase boom height. Both...

It’s always difficult to forecast weather, but if dry field conditions persist, the potential for combine and field fires this fall will continue to be a problem. There have already been dozens of significant field fires around the state,...
