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.
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
ISU Extension ag engineer Mark Hanna told attendees that a proper planter setting is critical for the row crop. He advises placing the corn seed at a soil depth of 2 inches using down pressure to ensure consistency of seed placement, and having the disk openers set such that they would hold a piece of … Continue reading Hanna: Integrating cover crops and livestock operations
In a recent Iowa Learning Farms webinar by Iowa State University Agronomist Matt Helmers, he dispelled some myths and misconceptions about water quality and drainage problems in corn and soybean fields.
Harvested corn, like all food, can spoil or grow mold in certain situations. Farmers have to take care to keep their product safe to sell. Last fall, there was a large crop and farmers had to pile grain. On top of that, the humidity or dew point was high, so there are concerns that the … Continue reading Hurburgh: Grain storage concerns after warm winter
Jay Harmon has been named the interim associate dean for extension and outreach programs and the interim director of Agriculture and Natural Resources Extension in the College of Agriculture and Life Sciences at Iowa State University.
“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
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 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
Iowa State University College of Agriculture and Life Sciences presented awards to faculty and staff March 9. The award winners included: The Team Award went to the Bioplastics for the Green Industry Team. This interdisciplinary team has made significant contributions through research, extension and graduate education to improve the sustainability of specialty crop production. Producers … Continue reading ISU College of Agriculture and Life Sciences presents outstanding faculty and staff awards
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.
