Researchers find fertilizer choice can affect methanogen activity in soil

FAYETTEVILLE, Ark. — University of Arkansas System Division of Agriculture research in rice may lead to more sustainable crop production in Arkansas and around the world.

The quest for increased sustainability in agriculture and other industries includes examining greenhouse gases and how they’re generated. In the U.S.,  only a small fraction of greenhouse gases are attributed to agriculture – 8.6 percent, according to the Environmental Protection Agency.  Within that small fraction, rice production is classed as a minor methane source. Nevertheless, greenhouse gas emissions, however small, may have an economic impact on Ag industries at some point in the future.

“Tackling large-scale problems often takes a one-step-at-a-time approach,” said Jean-Francois Meullenet, head of the Arkansas Agricultural Experiment Station, the research arm of the Division of Agriculture. “Research our faculty is conducting, including Dr. Brye’s important body of work in rice, is part of a broader effort to increase agricultural productivity for our farmers, both short- and long-term, while also increasing agriculture’s sustainability.”
