Agriculture is a major nonpoint source of phosphorus (P) in the Midwest, but how surface runoff and tile drainage interact to affect temporal concentrations and fluxes of both dissolved and particulate P remains unclear. Our objective was to determine the dominant form of P in streams (dissolved or particulate) and identify the mode of transport of this P from fields to streams in tile-drained agricultural watersheds. We measured dissolved reactive P (DRP) and total P (TP) concentrations and… Expand
Contributions of systematic tile drainage to watershed-scale phosphorus transport.
TLDR
The results of this study show that in systematically tile-drained headwater watersheds, the amount of P delivered to surface waters via tile drains cannot be dismissed and development and implementation of best management practices (BMPs) must jointly consider economic and environmental benefits. Expand
Catchment-scale Phosphorus Export through Surface and Drainage Pathways.
TLDR
Monitoring of P fate and transport in drained areas provided evidence that particulate P losses in drainage were greater than dissolved P losses, indicating that frequent, small storms have the potential to result in extreme losses. Expand
Orthophosphorus Contributions to Total Phosphorus Concentrations and Loads in Iowa Agricultural Watersheds.
TLDR
Evaluated Iowa rivers found systematic variation in the annual mean ratios of OP to total P (TP) concentrations and loads and found Orthophosphorus contributions from croplands would be greater in watersheds characterized by widespread tile drainage and well-drained soils, whereas cropland TP export would be dominated by particulate P in dissected till plains with poorly drained soils.

Phosphorus loading and ecological impacts from agricultural tile drains in a west Michigan watershed
Abstract Phosphorus (P) loading from nonpoint sources is often implicated as a contributing factor to the proliferation of algal blooms in freshwater ecosystems. However, the influence of subsurfaceExpand
Phosphorus fractions in discharges from artificially drained lowland catchments (Warnow River, Baltic Sea)
Understanding phosphorus (P) dynamics, from inland sources to the sea, is essential for developing strategies to reduce P loads. In this study, we examined concentrations, fractions, and associationExpand
Phosphorus losses from agricultural watersheds in the Mississippi Delta.
TLDR
Results indicate that applying P fertilizer in the spring may be recommended to reduce potential ortho-P loss during the fallow winter season; in addition, conservation practices may reduce potential TP loss associated with soil loss. Expand
Characterizing phosphorus dynamics in tile-drained agricultural fields of eastern Wisconsin
Summary Artificial subsurface drainage provides an avenue for the rapid transfer of phosphorus (P) from agricultural fields to surface waters. This is of particular interest in eastern Wisconsin,Expand
Nutrient Content at the Sediment-Water Interface of Tile-Fed Agricultural Drainage Ditches
Extensive network of tile drains present in the Midwest USA accelerate losses of nutrients to receiving ditches, rivers and eventually to the Gulf of Mexico. Nutrient inputs from agriculturalExpand
Storm phosphorus concentrations and fluxes in artificially drained landscapes of the US Midwest
This study investigates phosphorus (P) concentrations and fluxes in tile drains, overland flow, and streamflow at a high temporal resolution during 7 spring storms in an agricultural watershed inExpand
Characterizing bioavailable phosphorus concentrations in an agricultural stream during hydrologic and streambed disturbances
TLDR
A novel yeast-based bioassay is used with unfiltered sample water to estimate BAP concentrations during two storms, and downstream of a reach where management-associated dredging disturbed the streambed, to suggest that BAP export can exceed SRP, particularly when streams are not in equilibrium.

Particulate phosphorus transport within stream flow of an agricultural catchment.
TLDR
Monitoring of the Bog Burn drains a dairying catchment in Southland, New Zealand, and has been monitored at fortnightly intervals over a 12-mo period for suspended sediment, dissolved reactive phosphorus (DRP), and total phosphorus (TP), indicated that trapped sediment was derived from topsoil and entered the stream either through tile drainage or, to a lesser extent, overland flow.

Kinetics and Modeling of Dissolved Phosphorus Export from a Tile‐Drained Agricultural Watershed
Agricultural runoff can be a source of P, a limiting factor for freshwater eutrophication. To develop a simple method to estimate P export from the cropland, we studied 1.2-μm filtered dissolvedExpand

Timing of riverine export of nitrate and phosphorus from agricultural watersheds in Illinois: implications for reducing nutrient loading to the Mississippi River.
TLDR
A program of intensive, long-term monitoring allowed us to assess how nutrient export was distributed across the range of discharge that occurred at each site and to examine mechanistic differences between NO3(-)-N and DRP export from the watersheds and simple simulations showed that reducing in-stream nutrient loads by as much as 50% during periods of low discharge would not affect annual nutrient export fromThe Illinois watersheds.

Sources of phosphorus exported from an agricultural watershed in Pennsylvania
Abstract Freshwater eutrophication is usually controlled by inputs of phosphorus (P). As point source controls have decreased P inputs, the relative contributions of nonpoint inputs from agricultureExpand
Phosphorus budgets and riverine phosphorus export in northwestern Ohio watersheds.
TLDR
Detailed water quality studies show that riverine export of total phosphorus (TP) has decreased by 25 to 40% and soluble reactive phosphorus (SRP) by 60 to 89%, both due primarily to decreases from nonpoint sources. Expand

Phosphorus is the limiting factor for primary production in most freshwater ecosystems. In many areas, diffuse P losses from intensively cultivated land cause severe eutrophication of surface waters.Expand
