Interpretive Summary:

Technical Abstract: Integrated crop-livestock (ICL) production systems provide opportunities to leverage synergies among multiple enterprises for improved ecosystem service outcomes. Understanding ICL management effects on soil properties and soil-atmosphere gas flux dynamics is critically important for designing practices that improve soil quality while limiting emissions of radiative gases to the atmosphere. Previous research documenting ICL management effects on near-surface soil properties and soil-atmosphere gas flux dynamics has largely occurred in tropical regions. Making inferences from that body of research to temperate, semiarid conditions like the northern Great Plains is difficult. Therefore, we sought to quantify management effects on near-surface soil properties and soil CO2 efflux in a long-term ICL study near Mandan, ND USA. Treatments included grazed and ungrazed crop/forage rotations under no-till management. Results from an intensive measurement campaign conducted during the 2019 growing season will be presented.
