“…In a field study of Midwestern collection ditches, Smith and Huang (2010) observed decreased P exports in dredged ditch reaches versus undredged reaches for up to 1 yr after dredging (similar to Shigaki et al, 2008, and the present study; Fig. 2b).…”

“…Our finding that dredging lowered effluent P relative to the control when hydrology was held constant is consistent with Smith and Huang (2010) and Shigaki et al (2008). Disrupted materials from dredged and undredged ditches from the same site where our intact soil mesocosms were taken were compared for their P-release potential by Shigaki et al (2008).…”

“…Midwestern collection ditches are secondary ditches that primarily drain tile, function and behave much like streams (featuring near-constant to constant flow, whether recently dredged or not), and likely are neither as acidic nor dominated by Fe as the coastal plain soils of this study. Nevertheless it makes intuitive sense that removal of high-P materials would lower ditch free water P concentrations, as observed in Smith and Huang (2010), Shigaki et al (2008), and here (Fig. 2b).…”

“…It is important to understand how common ditch management practices such as dredging and controlled drainage affect ditch P retention and transport Sharpley et al, 2007;Smith and Pappas 2007;Shigaki et al, 2008). Dredging removes accumulated materials to intercept rising water at greater depth and has produced, in a midwestern context, increased P release in postdredge sediments in fluvaria (Smith et al, 2006;Smith and Pappas, 2007) and decreased P concentrations in the field (Smith and Huang, 2010). Controlled drainage restricts flow to retain sediments, decreases export of dissolved constituents, and raises the water table to promote denitrification (Gilliam and Skaggs, 1986;Evans et al, 1995;Kröger et al, 2008).…”

Hydrology and Soil Manipulations of Iron‐Rich Ditch Mesocosms Provide Little Evidence of Phosphorus Capture within the Profile

et al. 2017

Agricultural drainage ditches function as first-order streams and affect nutrient management. Soil mesocosms from a ditch featuring a vertical (increasing upward) gradient in iron (Fe) and phosphorus (P) were subjected to hydraulic and soil treatments. These manipulations mimicked aspects of dredging and controlled drainage and inspected the soil release and retention of P. Treatments did not remove P from simulated groundwater. Throughput water either gained in P (lack of dredging, especially under Fe-reducing conditions) or had P concentrations indistinguishable from input water (dredging). Undredged mesocosms, when Fe-reducing, released Fe and P simultaneously. Simultaneous release of P and Fe from our Fereducing mesocosms indicates a mechanism whereby P capture occurs by Fe precipitation upon emergence to aerated surficial waters. Upwelling and surficial phases of ditch hydrology and the lowering of the ditch surface on dredging complicate interpretation of traditional means of describing ditch P retention and release.

“…This can result in increased bank erosion (hence particulate P loss) and removal of bed materials with a high P sorption capacity leading to ditches becoming a P source rather than a P sink Sharpley et al, 2007;Smith and Pappas, 2007;Shigaki et al, 2008). In some instances, however, short-term increases in P retention have been observed following ditch dredging (Smith and Huang, 2010). As is the case with tile-drained fields, many questions are still to be answered regarding the use of drainage ditches for effectively removing water from agricultural fields without significantly increasing risks of P loss.…”

Phosphorus Fate, Management, and Modeling in Artificially Drained Systems

et al. 2015

Phosphorus (P) losses in agricultural drainage waters, both surface and subsurface, are among the most difficult form of nonpoint source pollution to mitigate. This special collection of papers on P in drainage waters documents the range of field conditions leading to P loss in drainage water, the potential for drainage and nutrient management practices to control drainage losses of P, and the ability of models to represent P loss to drainage systems. A review of P in tile drainage and case studies from North America, Europe, and New Zealand highlight the potential for artificial drainage to exacerbate watershed loads of dissolved and particulate P via rapid, bypass flow and shorter flow path distances. Trade-offs are identified in association with drainage intensification, tillage, cover crops, and manure management. While P in drainage waters tends to be tied to surface sources of P (soil, amendments or vegetation) that are in highest concentration, legacy sources of P may occur at deeper depths or other points along drainage flow paths. Most startling, none of the major fate-and-transport models used to predict management impacts on watershed P losses simulate the dominant processes of P loss to drainage waters. Because P losses to drainage waters can be so difficult to manage and to model, major investment are needed (i) in systems that can provide necessary drainage for agronomic production while detaining peak flows and promoting P retention and (ii) in models that can adequately describe P loss to drainage waters.
