Well-drained agricultural lands had higher transport of NO₃-N in the soil profile and groundwater due to increased N leaching. Poorly-drained agricultural lands had lower NO₃-N due to extensive drainage ditches and anaerobic soil conditions promoting denitrification. The performance of WCCs varied by crop rotations (i.e., continuous corn and corn-soybean), with increased N uptake following soybean crops due to the increased soil mineral N availability by mineralization of soybean residue compared to corn residue. The WCCs can reduce N leaching where baseline NO₃-N loads are high in well-drained soils and/or when residual and mineralized N availability is high due to the cropping practices. The findings suggested that WCC implementation plans should be established in watersheds according to local edaphic and agronomic characteristics for reducing N leaching.]]> Wed 11 Apr 2018 15:37:35 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32241 Thu 21 Oct 2021 12:51:23 AEDT ]]>
