Agricultural watersheds in the upper Midwest are the major source of nutrients to the Mississippi River and Gulf of Mexico, but temporal patterns in nutrient export and the role of hydrology in controlling export remain unclear. Here we reporton NO3(-)-N, dissolved reactive phosphorus (DRP), and total P export from three watersheds in Illinois during the past 8-12 years. Our program of intensive, long-term monitoring allowed us to assess how nutrient export was distributed across the range of… Expand
Effect of variable annual precipitation and nutrient input on nitrogen and phosphorus transport from two Midwestern agricultural watersheds.
TLDR
These two watersheds are within 150 km of one another and have similar dominant agricultural systems, but differences in climate and cropping inputs affected amounts and timing of nutrient transport. Expand
Nitrate-nitrogen export: magnitude and patterns from drainage districts to downstream river basins.
TLDR
Water yields were consistent with prior tile drainage studies in Iowa and the upper Midwest, but associated NO-N concentrations and losses were among the highest reported for plot studies and higher than those found in small watersheds. Expand
Subsurface nutrient export from a cropped field to an agricultural stream: Implications for targeting edge-of-field practices
Abstract It is understood that the major transport pathways for the soluble nutrients nitrate (NO3-N) and orthophosphorus (OP) from cropped fields to streams in the U.S. Cornbelt are tile drainageExpand
Phosphorus transport pathways to streams in tile-drained agricultural watersheds.
TLDR
Concentrations of DRP and PP in tiles increased with discharge, indicating tiles were a source of P to streams, and particulate P was the dominant form during overland runoff events, which greatly affected annual TP loads. Expand
Dynamics of nitrate and chloride during storm events in agricultural catchments with different subsurface drainage intensity (Indiana, USA)
Summary Drainage tiles buried beneath many naturally poorly drained agricultural fields in the Midwestern U.S. are believed to “short circuit” pools of NO 3 - -laden soil water and shallowExpand
Sources of nitrate yields in the Mississippi River Basin.
TLDR
It is found that river runoff times fertilizer N input was the major predictive term, explaining 76% of the variation in the model, and the greatest nitrate N yields corresponded to the highly productive, tile-drained cornbelt from southwest Minnesota across Iowa, Illinois, Indiana, and Ohio.

The impact of fertilization and hydrology on nitrate fluxes from Mississippi watersheds
The watersheds of the Mississippi are some of the most intensively managed agricultural basins in the world. As such, they receive high loadings of nitrogen and export a large amount of nitrate toExpand

Long-Term Observations of Nitrogen and Phosphorus Export in Paired-Agricultural Watersheds under Controlled and Conventional Tile Drainage.
TLDR
Overall, the study results indicate that CTD is an effective practice for reducing watershed scale fluxes of stream water, N, and P during the growing season and suggest physical abatement byCTD is the means by which nutrient fluxes are predominantly reduced at these scales. Expand

Evaluation of nitrate nitrogen fluxes from a tile-drained watershed in central Iowa.
TLDR
Assessment of discharge and NO3-N fluxes passing the outlet of an Iowa watershed and two of its tile-drained subbasins from mid-1992 through 2000 found that agricultural and wetland best management practices are needed to achieve water quality goals in tile- drained watersheds. Expand
Nitrogen Balance in and Export from an Agricultural Watershed
Surface water nitrate (NO 3 - ) pollution from agricultural production is well established, although few studies have linked field N budgets, NO 3 - loss in tile drained watersheds, and surface waterExpand

Transport and fate of nitrate in headwater agricultural streams in Illinois.
TLDR
Assessment of headwater streams in agricultural areas of east-central Illinois found that most NO(3)-N in these headwater sites appeared to be exported to downstream water bodies rather than denitrified, suggesting previous estimates of N losses through in-stream denitrification may have been overestimated.

TLDR
Comparisons using nonparametric, nonlinear trend fits (LOWESS) suggest that changes in fertilizer and manure application rates are the most important cause of trends in phosphorus and total Kjeldahl nitrogen; point sources are insufficient to account for the phosphorus trends. Expand
