Highlights Denitrifying woodchip bioreactors treat nitrate-N in a variety of applications and
geographies. This review focuses on subsurface drainage bioreactors and bed-style …

Abstract Nitrate (NO3−) is highly water-soluble and considered to be the main nitrogen
pollutants leached from agricultural soils. Its presence in aquatic ecosystems is reported to …

Woodchip bioreactors are widely known as a best management practice to reduce excess
nitrate loads that are discharged with agricultural leachates. The aim of this study was to …

Cold temperatures limit nitrate-N load reductions of woodchip bioreactors in higher-latitude
climates. This two-year, on-farm (Willmar, Minnesota, USA) study was conducted to …

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

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

Woodchip denitrification walls offer a potentially useful way for passive in situ remediation of
groundwater nitrate pollution, yet because of the low redox state they induce on the …

In Australia, declining water quality in the Great Barrier Reef (GBR) is a threat to its marine
ecosystems and nitrate (NO3−) from sugar cane-dominated agricultural areas in the coastal …

Woodchip bioreactors have the capability to promote the reduction of reactive nitrogen in the
nitrate (NO 3−) form to dinitrogen (N 2), a harmless gas in the atmosphere. Nevertheless …

Abstract Nitrate (NO 3−) removal in denitrifying bioreactors is influenced by flow, water
chemistry, and design, but it is not known how these widely varying factors impact the …
