Kohl: Warm temps bring storage considerations

In the past couple of weeks, high temperatures have been well above average, with dew point temperatures above grain temperatures. This can cause grain bins to act like solar collectors on the south side. The southwest side heats up, causing the air to rise and dry the grain, says Kris Kohl, Iowa States University agricultural engineer.

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

ABE faculty and extension specialists to present at farmland drainage workshop

Various aspects of farmland drainage will be the focus of a daylong workshop March 3 at the Iowa Bioprocess Training Center in Eddyville. The program is from 8:30 a.m. to 4:15 p.m. “This workshop is being offered due to the increased interest in this topic the past year,” says Kapil Arora, field agricultural engineer with Iowa … Continue reading ABE faculty and extension specialists to present at farmland drainage workshop

Ramirez: Minimum Ventilation – Design versus operation

By Brett C. Ramirez, Iowa State University Department of Agricultural and Biosystems Engineering Graduate Research Assistant. As we enter the middle of winter, it is essential we revisit the importance and role of Minimum Ventilation. It is understood that poor ventilation during the winter months can lead to moisture problems, hazardous gas build-up, and in general, … Continue reading Ramirez: Minimum Ventilation – Design versus operation

Andersen: Workshop offers insight on water quality issues

When Iowans talk about water quality, they sometimes think the major problem is manure. “I’m a big fan of the nutrient reduction strategy,” says Iowa State University Extension Agricultural Engineer Dan Andersen. “I’m not a big fan of when people call it the manure reduction strategy.” Andersen was one of the speakers at a manure management workshop … Continue reading Andersen: Workshop offers insight on water quality issues

Schwab: Fatalities jump for hobby farmers

Going against almost all other industry currents, farming retirements exist only on paper, echoes Charles Schwab, a professor of agricultural and biosystems engineering at Iowa State University. “Farmers keep working at some level and you see these injuries mount. We’ve recorded so many farm injuries with 70- and 80-year-olds and that makes agriculture so different.”

Andersen: Producers respond to H2S deaths

When manure is disturbed or agitated, H2S is released into the air “in bursts,” says Dan Andersen, ag and biosystems engineering professor at Iowa State University. Air concentrations can increase a thousand-fold, reaching deadly levels within seconds.
