Connecting the soil health–water quality nexus under surface‐irrigated conservation tillage

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Intense tillage degrades soil health, worsens soil structure, and accelerates nutrient and sediment transport to vulnerable water bodies. Unfortunately, few studies have measured both soil health and water quality under conservation tillage, particularly in semi‐arid furrow‐irrigated fields, limiting our understanding of tillage impacts in ...

Evaluating the potential for snowmelt phosphorus losses from perennial forage crops

open access: yesJournal of Environmental Quality, EarlyView.
Abstract In cold regions, there is concern that losses of P with snowmelt runoff following freeze and thaw of vegetation may be greater from perennial forages relative to annual crops. We evaluate the drivers of P losses with snowmelt runoff over a network of field‐scale small watersheds in Manitoba, Canada, following annual crops (59 site‐years ...

Field‐scale evaluation of ecosystem service benefits of bioenergy switchgrass

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Purpose‐grown perennial herbaceous species are nonfood crops specifically cultivated for bioenergy production and have the potential to secure bioenergy feedstock resources while enhancing ecosystem services. This study assessed soil greenhouse gas emissions (CO2 and N2O), nitrate (NO3‐N) leaching reduction potential, evapotranspiration (ET ...
