A Comparison of Conventional Annual and Alternative Perennial Cropping Systems Under Contemporary and Future Precipitation Scenarios in the US Prairie Pothole Region

Effects of land management on inundation of prairie pothole wetlands in the Des Moines Lobe using AnnAGNPS

“…Changing management of low productivity farmed potholes may be an opportunity to restore some ecosystem services at a lower cost than removing high productivity upland areas from production. Evidence suggests that perennial crops perform better in potholes compared to corn (Zea mays L.) and soybean (Glycine max) crops (Bailey-Serres et al, 2012;Edmonds, 2017;Mann et al, 2013).…”

“…Incorporating alternative management practices, such as conservation restoration programs or planting perennial grasses, may help to minimize or eliminate crop yield losses in flood-prone pothole areas (Edmonds, 2017).…”

An assessment of the potential for biomass sorghum to be produced as a dedicated bioenergy crop in Iowa, USA

“…Before running a simulation with Agro-IBIS, a "spin-up" and "restart" run has to be completed in order to build up the soil carbon and nitrogen pools (Kucharik, 2003;Vanloocke, Bernacchi and Twine, 2010;Edmonds, 2017;Ferin et al, 2021). The spin-up period was from 1750-1910, where natural vegetation (no agricultural crops) are grown for 160 years to simulate pre-settlement ecology.…”
