Silage research study finds cause and solution for greenhouse gas emissions

Researchers at Kansas State University have determined a cause and potential solution for greenhouse gas emissions from silage.

Jeongdae Im, an associate professor of civil engineering, says his team tested simulated silage from corn, alfalfa and sorghum and monitored emissions over a four-week period.

“A group of bacteria called the denitrifiers are responsible for nitrous oxide emissions from silage making,” he says.

The experiment also showed that when the chemical chlorate was applied to silage it significantly mitigated greenhouse gas emissions.

Im says the next step will be a full-scale demonstration that also includes testing the potential impact on the meat production process…

‘To see if there’s any remaining residual, chlorate or other chemicals that we added in the process. I don’t believe that that will be the case,” he says.

Corteva co-authored the study and the research was supported by a National Science Foundation grant.
