Recent research has identified how crop rotation in Wisconsin can influence labile pools of C and N. In-short, on Mollisols of southern Wisconsin, big changes in management are required to increase these labile pools. Kalyn Diederich’s (MS Soil Science & Agroecology) poster titled “Increasing labile C and N pools in agricultural soils requires a change in system, rather than practice” was awarded honorable mention in the student poster competition at the Ecology of Soil Health Summit in Fort Collins, CO. This research shows that it is the big shifts – i.e. shifting from grain-based rotations to forage-based rotations to pasture – that cause increases in these biological indicators of soil health, rather than management shifts (e.g. tillage) within a cropping system.
