Interpretive Summary:

Technical Abstract: Multiple enterprises in integrated crop-livestock (ICL) production systems can generate management synergies to reduce environmental degradation from agricultural lands. Among the many environmental metrics associated with agricultural production, nitrous oxide (N2O) flux is a prevalent factor in dictating the global warming potential of management practices in semiarid regions. Unfortunately, there is limited understanding globally of ICL production system effects on this important greenhouse gas. Therefore, we measured N2O flux from ICL management practices near Mandan, ND USA using static chamber methodology over a 3-yr period (Oct 2016 – Oct 2019). Evaluated treatments included grazed and ungrazed cropland and grassland on a site with gently rolling topography and fertile Haplustoll soils. Treatment effects on daily and cumulative N2O flux, along with factors affecting flux dynamics, will be presented.
