A review of the development and implementation of the critical source area concept: A reflection of Andrew Sharpley's role in improving water quality

Journal of Environmental Quality, EarlyView.
Abstract Critical source areas (CSAs) are small areas of a field, farm, or catchment that account for most contaminant loss by having both a high contaminant availability and transport potential. Most work on CSAs has focused on phosphorus (P), largely through the work in the 1990s initiated by Dr.

Phosphorus lability across diverse agricultural contexts with legacy sources

Journal of Environmental Quality, EarlyView.
Abstract The buffering of phosphorus (P) in the landscape delays management outcomes for water quality. If stored in labile form (readily exchangeable and bioavailable), P may readily pollute waters. We studied labile P and its intensity for >600 soils and sediments across seven study locations in the United States. Stocks of labile P were large enough

Surface water irrigation reservoirs improve groundwater recovery in a heavily stressed aquifer

Journal of Environmental Quality, EarlyView.
Abstract Expansion of irrigated cropland area in eastern Arkansas has led to the formation of regional cones of depression and creation of critical groundwater areas for the Mississippi River Valley alluvial aquifer (MRVA) in Arkansas. In response, use of surface water reservoirs for irrigation in the Grand Prairie critical groundwater area (GPCGA) has

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

Journal 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 ...

Environmental sustainability in US dairy farms: Policies, practices, and outcomes

Journal of Environmental Quality, EarlyView.
Abstract Improving sustainability on US dairy farms has become a critical focus across the industry. As dairy farms continue to consolidate, there is a growing need to identify scalable, implementable soil health management practices that enhance environmental sustainability in the fields managed by the dairy.
