While enabling economically viable use of poorly drained soils, artificial subsurface
drainage has also been found to be a significant pathway for nutrient transfers from …

Denitrifying bioreactors are organic carbon‐filled excavations designed to enhance the
natural process of denitrification for the simple, passive treatment of nitrate‐nitrogen …

There is a need to evaluate high surface nitrate concentrations across agricultural
watersheds, both spatially and temporally, to increase understanding of source and timing of …

Landscapes typically deemed at risk from leached losses of nitrogen (N) and phosphorus
(P) are those with short subsurface hydrologic time lags. Due to the short time it takes …

A denitrification bed is a system that can reduce the nitrate concentration in subsurface
drainage water. There is a need to investigate the carbon quality of old woodchips to gain a …

Denitrifying woodchip bioreactors are a best management practice to reduce nitrate–
nitrogen (NO3–N) loading to surface waters from agricultural subsurface drainage. Their …

Subsurface flow constructed wetlands with wood chips (SSF-CWs) have proven to effectively
reduce the loss of nitrogen (N) from agricultural fields to surface water, however in some …

Denitrification bioreactors are an effective edge-of-field conservation practice for nitrate (NO
3) reduction from subsurface drainage. However, these systems may produce other …

Runoff from farm roadways within farm boundaries are acknowledged as a year-round
source of pollutants discharging to surface water, particularly during the main grazing …

Denitrifying bioreactors are edge-of-field structures that remove excess nitrogen (N) from
intercepted agricultural drainage by supporting the activity of denitrifying microorganisms …
