Hanna: Match sprayer to new herbicides

Don’t assume application requirements of new products and strategies to control resistant weeds will mimic those of glyphosate and other products you’re familiar with, cautions Dr. Mark Hanna, Iowa State University Extension Agricultural Engineer. Look now at labels of herbicides you’re considering for use next spring to prepare for proper nozzles and travel speeds, and … Continue reading Hanna: Match sprayer to new herbicides

Hanna: Installing solar arrays becomes more attractive for farmers

“Not many people realize this, but Iowa is in the top third of states in terms of solar potential,” said Mark Hanna, agricultural engineering specialist with Iowa State University Extension and Outreach. “The cost per watt for generating electricity has been dropping steadily, down to about $3 per watt as opposed to $10-15 per watt … Continue reading Hanna: Installing solar arrays becomes more attractive for farmers

Hanna, ISU extension and outreach advises combine adjustment for wet fields

As the fall harvest continues to push on across the Midwest, frequent storms and rainfall have dampened many producers’ fields, and this trend will likely continue through October. Dr. H. Mark Hanna, an agricultural engineer with Iowa State University, has recently published a series of combine adjustment tips that could help producers better cope with … Continue reading Hanna, ISU extension and outreach advises combine adjustment for wet fields

Hanna: Top causes for mechanical corn yield loss

Harvest equipment can have a lot to do with how much yield loss you experience. Being attentive to both equipment and field conditions is critical in minimizing yield loss. Research shows during harvest, 60% of yield loss typically occurs at the corn head, according to Iowa State University Extension agricultural engineer Mark Hanna.

Strip-till technologies focus of ISU field day, July 13

The event will begin with a discussion of agronomic considerations for strip-tillage. Sessions on fall versus spring strip-tillage and the use of UAV technology for crop scouting will follow. The day will conclude with lunch and an optional field tour of strip-till research at Iowa State. Matt Darr and Mark Hanna will make presentations during the … Continue reading Strip-till technologies focus of ISU field day, July 13

Hanna: Cut combine maintenance time with a preharvest inspection

A common issue with any machinery stored for long periods of time can be especially damaging to electronic components, wiring and sensors, says Iowa State University Extension agricultural engineer Mark Hanna. “It’s probably been 10 or 11 months since you’ve run that machine, so it’s important to watch for rodent damage.”
