There's more to biofuel production than yield
"Corn prices are currently attractive to farmers, but with the exception of biomass yield, all other services were greater in the perennial grass crops," Landis said.
"If high commodity prices continue to drive conversion of these marginal lands to annual crop production, it will reduce the flexibility we have in the future to promote other critical services like pollination, pest suppression and reduction of greenhouse gases."
Additional MSU researchers involved in the study include Ben Werling, Timothy Dickson, Rufus Isaacs, Katherine Gross, Carolyn Malmstrom, Leilei Ruan, Philip Robertson, Thomas Schmidt, Tracy Teal and Julianna Wilson.
Scientists from the University of Wisconsin, University of Nebraska, Bard College and Trinity Christian College were part of the research.
The work was also funded by the U.S. Department of Energy and MSU AgBioResearch.
