Session Description: Subsurface (tile) drainage systems is an important pathway for nitrogen exports from agricultural fields to surface waters. Several existing or emerging practices aiming at minimizing nitrogen exports through subsurface agricultural drainage systems are being studied and evaluated throughout the US and the world. Collectively termed conservation drainage, these practices are agronomic or engineered approaches designed to optimize the source or timing of nitrogen availability to the crop; increase plant uptake of nitrogen; reduce drainage flow volume and/or increase denitrification. Abstracts discussing aspects of the practices including their efficiencies, impacts and adoption are invited.
