Riparian buffer located in an upland landscape position does not enhance nitrate-nitrogen removal

► The study emphasizes additional buffer width does not necessarily produce proportional groundwater water quality benefits. ► The conservation buffer was added in an upland landscape position and did not contribute to groundwater NO3−-N reduction. ► A reduction in NO3−-N was only observed through t...

Zusammenfassung:► The study emphasizes additional buffer width does not necessarily produce proportional groundwater water quality benefits. ► The conservation buffer was added in an upland landscape position and did not contribute to groundwater NO3−-N reduction. ► A reduction in NO3−-N was only observed through the existing hardwood forested buffer located downslope. ► Landscape position determined the effectiveness of this buffer and should be a primary metric for site selection.
