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”
Better distribution of manure nitrogen can help reduce the need to apply supplemental N as sidedressing in spring, thus resulting in cost savings and water quality benefits.
Dan Andersen, an ag engineer at Iowa State University, said between 25 and 30 percent of nitrogen, phosphorus and potassium needs are provided through manure usage. “We have plenty of room for more,” he told producers at the Iowa Pork Congress here Jan. 25.
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”
Kristina Craft is a graduate student working toward a master’s degree in agricultural and biosystems engineering. The goal of her graduate work is to increase understanding in the science involved in mitigating adverse water quality and soil health impacts of row crop systems while maintaining or improving upon production. Kurt Rosentrater, associate professor of agricultural …Continue reading “Craft and Rosentrater named to CALS Sustainability Task Force”

Matt Darr, an associate professor of agricultural and biosystems engineering at Iowa State University, called UAVs a “bleeding-edge technology” with great potential in agriculture. And faculty and students at Iowa State are playing a multifaceted role in advancing this emerging technology, he says. Iowa State engineers are developing software to make UAVs smarter and faster at …Continue reading “Birds-eye view of agriculture”
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”
Amy Kaleita, associate professor of agricultural and biosystems engineering, has many reasons for working with remote sensing. “I got into sensors because I think they’re cool and fun,” she says, “but also as a grad- uate student I did enough field work by hand that I thought, we’d never be able to answer these big questions …Continue reading “Soil to space”
