“…As had been previously reported (Moorman et al, 2010;Woli et al, 2010;Warneke et al, 2011a;Christianson et al, 2013a;Ghane et al, 2015), we found small N 2 O emissions from either Bioreactor 1 or 2 wood chip beds. However, our rates were generally greater than those reported by Christianson et al (2013a) for bioreactors with soil covers but similar to those without.…”

Tile drainage is the major source of nitrate in the upper Midwest, and end-of-tile removal techniques such as wood chip bioreactors have been installed that allow current farming practices to continue, with nitrate removed through denitrification. There have been few multiyear studies of bioreactors examining controls on nitrate removal rates. We evaluated the nitrate removal performance of two wood chip bioreactors during the first 3 yr of operation and examined the major factors that regulated nitrate removal. Bioreactor 2 was subject to river flooding, and performance was not assessed. ) in Years 2 and 3, overall removal efficiency was low (3 and 7% in Years 2 and 3, respectively). Based on a process-based bioreactor performance model, Bioreactor 1 would have needed to be 9 times as large as the current system to remove 50% of the nitrate load from this 20-ha field. et al., 2010b;Skaggs et al., 2012;Jaynes and Isenhart, 2014;David et al., 2015;Groh et al., 2015). The effectiveness of these practices is variable from location to location and temporally due to differing tile flow amounts and nitrate concentrations. Edgeof-field techniques have particular difficulty reducing nitrate loads during high-flow periods, when most transport occurs (Royer et al., 2006;Ikenberry et al., 2014;Moorman et al., 2015).Wood chip bioreactors have been installed at the end of tile lines from many fields in the Midwest. A wide range of nitrate removal effectiveness (up to 98% nitrate reductions) in laboratory and field studies has been reported in the literature (Greenan et al., 2009;Chun et al., 2009Chun et al., , 2010Moorman et al., 2010;Verma et al., 2010;Woli et al., 2010;Christianson et al., 2012b;Bell et al., 2015). Most have been designed as plasticlined trenches, filled with mixed-species wood chips, that receive tile flow from fields ranging from 1 to 20 ha in size (e.g., Woli et al., 2010;Christianson et al., 2012b). At low flow most of the tile water passes through the bioreactor, but at high flows they are designed so that water will bypass the wood chip bed (Christianson et al., 2012a). The published literature on the effectiveness of this technique is limited, and additional results are needed because bioreactors have been proposed in two state nutrient loss reduction strategies as a primary method for nitrate reductions (Iowa Nutrient Reduction Strategy, 2013; Illinois Nutrient Loss Reduction Strategy, 2015).One concern with any engineered denitrification technique is that nitrous oxide (N 2 O) could be released (Groh et al., 2015), trading a water quality problem for a greenhouse gas problem Journal of Environmental Quality MOVING DENITRIFYING BIOREACTORS BEYOND PROOF OF CONCEPT SPECIAL SECTION Core Ideas• Bioreactor performance decreased greatly after Year 1.• Tile water temperature was limiting factor as wood chips aged.• Little N 2 O emitted from wood chip bed.• Bioreactor would need to be six times larger for this field and nitrate load.

“…Incomplete denitrification can result in significant release of nitrous oxide (N 2 O), a potent greenhouse gas. Both gaseous N 2 O emission and dissolved N 2 O release in bioreactor effluent can be significant (Moorman et al 2010;Warneke et al 2010).…”

“…Their use is growing, particularly in intensive agricultural regions such as the Midwest United States, where the gains from N use efficiency can outweigh the purchase costs (43). Wood chip-filled trenches, known as denitrifying bioreactors, also show promise by increasing complete denitrification to N 2 (44,45).…”
