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

By Brett C. Ramirez, Iowa State University Department of Agricultural and Biosystems Engineering Graduate Research Assistant. To create a facility that performs at the level our pigs and producers desire, we must improve and unify ventilation design, construction integrity, control and monitoring.

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

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.
