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.
By Brett C. Ramirez* and Harishchandra Jadhav, Iowa State University Department of Agricultural and Biosystems Engineering Graduate Research Assistants. Proper air distribution from planned ceiling inlets plays a major role in providing an environment that is acceptable for both pigs and workers.
Ethanol plants need to be especially cautious of moldy corn this spring due to a humid fall and excessive amounts of corn stored in outdoor piles. Charles Hurburgh, Iowa State University Extension grain quality specialist and ABE professor, says mid- to late February will bring reports of moldy corn, hot spots and blue eye mold … Continue reading Hurburgh: Beware of moldy corn this spring
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
Hydrogen sulfide gas is a serious issue in and around barns with liquid manure storage. The decomposition of organic matter in manure results in the release of several gases: ammonia, carbon dioxide, methane and hydrogen sulfide among them. Most of the time these gases are emitted at low levels, but any time manure is being agitated … Continue reading Pit gases pose a danger in beef barns
