Abstract
- The article studies the effects of global warming potential and greenhouse gas intensity in irrigated cropping systems in northeastern Colorado. A no-till (NT) cropping systems study initiated in 1999 to evaluate soil organic carbon (SOC) sequestration potential in irrigated agriculture was used in this study to make trace of gas flux measurements for 3 years to facilitate a complete greenhouse gas accounting of global warming potential (GWP) and greenhouse gas intensity (GHGI). These multi-year data suggest that there is year-to-year variability in trace gas exchange, as demonstrated by Dobbie et al. (1999) in other systems and inter-annual variability in SOC exchange as well.
