Improving food systems in Iowa through industrial engineering

Improving food systems in Iowa requires a lot more than just a knowledge of agriculture. Anuj Mittal, Ph.D. candidate in industrial engineering (IE) at Iowa State University, has been part of a U.S. Department of Agriculture (USDA) study which will allow food hubs in Iowa to share supply chain best practices among each other and … Continue reading Improving food systems in Iowa through industrial engineering

Schwab describes evolution of rollover protective structures

The American Journal of Industrial Medicine says a 2008 report indicates farmers and farm workers 55 and over are nearly twice as likely to die in farm accidents. Of those fatalities, Tractors accounted for 46 percent of those deaths. Fortunately, there are groups working to make tractors safer. Chuck Schwab of Iowa State University Extension describes … Continue reading Schwab describes evolution of rollover protective structures

Helmers: Focusing on water quality

“We’ve been looking at these practices for a long time to identify how we can reduce nitrate loss from drainage systems and optimize crop production,” says Matt Helmers, ISU Extension ag engineering professor and a member of the team that helped develop the Iowa Nutrient Reduction Strategy, introduced in 2013.

Kohl: Bigger cattle require better facility design

Big cattle need plenty of room. The exact amount of recommended space per animal varies by the type of feed yard. Kris Kohl, Iowa State University Extension agricultural engineer, gave a rundown of stocking density guidelines at a cattle stewardship seminar at the Dickinson County Fairgrounds in Spirit Lake last month.

Shouse: Shade, sprinklers keep livestock cool

Calm and muggy days are particularly troublesome for feedlot cattle, says Shawn Shouse, Extension ag engineer with Iowa State University. Many feedlots are without shade, leaving cattle to sometimes bake in the summer sun. Some feedlots offer natural or manmade shade, and Shouse says adding even the smallest bit of shade can make a difference.

Ag engineering student brings aquaponics to ISU and beyond

For Sophie Rotole, a junior in agricultural engineering, it’s been a great experience for an undergraduate. “Miniponics 3.0 was a great success for me personally. It was a great opportunity to experience the engineering design process. I really enjoyed designing and constructing a product from start to finish and watching it function as intended,” she … Continue reading Ag engineering student brings aquaponics to ISU and beyond

Brenneman: Drainage design — for profit and water quality

“While subsurface drainage is important for crop production, we need to consider the design of these systems for proper function, as well as to minimize nitrate loss,” says Greg Brenneman, an Iowa State University Extension ag engineer. Drainage systems need to be designed for efficient collection of excess soil water, as well as adequately moving … Continue reading Brenneman: Drainage design — for profit and water quality

Shouse: Cattle building benefits factor into industry expansion

Shawn Shouse, Extension ag engineer with Iowa State University in Lewis, Iowa, says while most of the technology remains pretty much the same, interest among the cattle industry is growing. “Based on our survey, about half of the expansion in the beef industry over the past five years has been done with confined buildings,” he says. … Continue reading Shouse: Cattle building benefits factor into industry expansion

Iowa Grain Quality Initiative begins life-saving research in Rwanda

Iowa State University Extension and Outreach’s Iowa Grain Quality Initiative (IGQI) is embarking on a project in Rwanda assessing the impact of mycotoxins – toxic chemicals produced by fungi found in food crops. The program will sample and test animal feed grains in Rwanda and is slated to begin mid-March. Little research has been undertaken … Continue reading Iowa Grain Quality Initiative begins life-saving research in Rwanda
