Climate Change

KBS researchers discovered and quantified how different crop management practices can interact to provide novel opportunities for greenhouse gas mitigation by agriculture. These discoveries inform agricultural greenhouse gas policies worldwide.

Dr. Phil Robertson
A series of automated chambers for collection of naturally occurring greenhouse gas samples -- carbon dioxide, methane, and nitrous oxide -- in a wheat field at the Kellogg Biological Station LTER site.
J.E. Doll
The net global warming impact (GWI) of cropped and unmanaged ecosystems at the KBS LTER site. Row crops include corn, soybean, and wheat rotations. Unmanaged ecosystems include fields abandoned from agriculture 20 (Early) to 60 (Mid) years ago that are undergoing natural succession toward native deciduous forest (Late).
