Abstract
This paper examines six retrofitted tile drainage systems and the effect of Water Table Management (WTM) on nitrates in tile line effluent. These sites are from two different watersheds and include four irregular and two gridded tile drainage systems. One of the gridded sites has shown nitrate-loading reductions of up to 60% while under WTM, and the four irregular sites had statistically significant changes. Reductions at the gridded site were highly correlated to the time when the site was under WTM, and after release of the water table reduction percentages dropped significantly. Results are preliminary and suggestions for further research are provided.
