"During the growing season, nighttime low temperatures are rising. In the fall, winter, and spring, daytime highs are higher than they used to be. All these effects of the changing climate appear to intensify a microbial reaction called denitrification: In saturated soils and warmer temperatures, the plant food that crops depend on, nitrate nitrogen, is converted into nitrous oxide — a greenhouse gas that is emitted to the atmosphere.

"With less food in the soil, corn and other crops will yield less."

Prof. Tim Griffis is quoted in this article by MN Corn: "We need to come up with strategies that reduce nitrous oxide emissions." SWAC researcher Sam Strack is shown in the photo conducting research. Continue reading the full story on MN Corn's website.
