The midwestern United States offers some of the most productive agricultural soils in the
world. Given the cool humid climate, much of the region would not be able to support …

Rasouli, S., Whalen, JK and Madramootoo, CA 2014. Review: Reducing residual soil
nitrogen losses from agroecosystems for surface water protection in Quebec and Ontario …

As agriculture in the 21st century is faced with increasing pressure to reduce negative
environmental impacts while continuing to efficiently produce food, fiber, and fuel, it …

Much of the nonpoint N and P entering surface waters of the Midwest is from agriculture. We
determined if constructed wetlands could be used to reduce nonpoint N and P exports from …

Subsurface drainage is a beneficial water management practice in poorly drained soils but
may also contribute substantial nitrate N loads to surface waters. This paper summarizes …

Agriculture is a major nonpoint source of phosphorus (P) in the Midwest, but how surface
runoff and tile drainage interact to affect temporal concentrations and fluxes of both …

In an agricultural catchment area in Germany we analyzed water samples from five entry
routes for 2 insecticides, 5 fungicides and 13 herbicides. The sewage plant outlet and the …

Much work has been invested in the development of practices and technologies that reduce
nitrate losses from agricultural drainage in the US Midwest. While each individual practice …

This study examines spatiotemporal variability (event-based, seasonal) in the contribution of
drainage tiles within a basin to basin hydrologic discharge and soluble reactive phosphorus …

Nitrate from agricultural activity contributes to nutrient loading in surface water bodies such
as the Mississippi River. This study demonstrates a novel in‐stream bioreactor that uses …
