Abstract: Well-managed pastures support many ecosystem services, but in the Midwest US perennial pastures increasingly are converted to annual row crops mostly fed to confined livestock and ethanol refineries. This agronomic intensification increases yields but drives soil loss, climate change, water quality degradation, flooding, anti-microbial resistance, pesticide resistance, and biodiversity decline. Maintaining and expanding well-managed pastures for livestock production is key to more multifunctional agricultural landscapes, but we need better predictions about how ecosystem functions co-vary under alternative pasture management.
