Summary

One anticipated benefit of ecosystem restoration is water quality improvement. This study evaluated NO3-N and phosphorus in subsurface waters during prairie establishment following decades of row-crop agriculture. A prairie seeding in late 2003 became established in 2006. Wells and suction cup samplers were monitored for NO3-N and phosphorus. Nitrate-N varied with time and landscape position. Non-detectable NO3-N concentrations became modal along ephemeral drainageways in 2006, when average concentrations in uplands first became <10 mg NO3-N L−1. This decline continued and upland groundwater averaged near 2 mg NO3-N L−1 after 2007. The longer time lag in NO3-N response in uplands was attributed to greater quantities of leachable N [...]
