Subsurface drainage describes the process of removal of that water which has infiltrated into the soil in excess of the amount that can be held by capillary forces against the force of gravity.
Soils that require accelerated subsurface drainage typically have some impermeable or slowly. Regulation and control of agricultural water pollution is unique and difficult to accomplish.
Water quality standards are often proposed without adequate consideration of the overall economic impact on agricultural production. This article illustrates how economists and physical scientists can cooperate to develop appropriate control strategies for agricultural water by: 3.
An economic analysis showed that the annualized installation costs for the three bioreactors were between $60 and $ per hectare of effective drained area.
(13%–43% nitrogen reduction. The effect of controlled drainage (CD) on nitrogen (N) losses from controlled irrigation (CI) paddy fields through subsurface drainage and ammonia volatilization (AV) was investigated by managing water table control levels (WTC) with a lysimeter equipped with an automatic water Cited by: 1.
Controlled drainage reduced total nitrogen loading by an average of 94%. • 67% of nitrogen reduction via drain outlet was due to enhanced denitrification. • The nitrogen reduction efficiency reduced to 66% if considering lateral seepage. • Controlled drainage raised daily water table depth significantly by 15 cm.
Developing drainage water management (DWM) systems in the Midwest to reduce nitrogen (N) transport to the northern Gulf of Mexico hypoxic zone requires understanding of the long-term performance of these systems. Few studies have evaluated long-term impacts of DWM, and the simulation of controlled drainage (CD) with the Root Zone Water Quality Model (RZWQM) is limited, while shallow drainage.
A partial economic analysis was conducted for maize (Zea mays L.) at nitrogen (N) fertilizer treatments of 0, 84, and kg ha − 1 under full irrigation (FIT), limited irrigation (75% FIT), and rainfed settings for all growing seasons and then compared to crop water productivity (CWP) measured as crop water use efficiency (CWUE.

Agron. 81, 1. Introduction. Artificial subsurface drainage systems in the Midwestern “Corn Belt” region have allowed for increased productivity over the past century, but nitrate (NO 3 −) losses in drainage have caused significant multi-scale environmental concerns.Much work has been done developing and advancing practices to reduce NO 3 − losses in subsurface agricultural drainage.
An economic analysis showed that the cost of installing subsurface drainage systems was readily justified by annual increased rice and canola yields. Based on the results, the introduction of the subsurface drainage resulted in an increase in both crop yield and cropping intensity in. The study reveals that after introduction of subsurface drainage, the water table depth has gone down to per cent and drain water salinity has showed a tremendous reduction of 98 per cent.
DRAINMOD-NII can predict the impact of system design and operational parameters on transport of various forms of nitrogen within the soil profile and losses in subsurface flow and runoff.
An economic analysis from operating the designed water table control system needs to be conducted for the farmer’s use in evaluating the benefits of. The longer the retention time or length of time the water was in the bioreactor, the greater the rate of nutrient removal. Results indicated consistent reduced conditions (i.e.
improved conditions for denitrification) within the bioreactors when acetate was added to the subsurface drainage water. Potential areas for future research.
Demonstrate and evaluate the sediment, nitrogen and phosphorus reduction effectiveness, biogeochemical processes, hydrologic impacts, and construction design criteria of common agricultural drainage water management practices to address research gaps identified in the Minnesota Agricultural Best Management Practice (BMP) Handbook.
The water in the bypass system was not treated by the bioreactor. Automated equipment collected 8 sub-samples every 3 hours.
For more information about the experiment design and monitoring equipment, please refer to the method section of the final report (PDF). Sample Analysis. Water samples were analyzed for - Nitrate and nitrite-nitrogen. Constructed wetlands have been proposed as cost-effective and more targeted technologies in the reduction of nitrogen and phosphorous water pollution in drainage losses from agricultural fields in Denmark.
Using two pig farms and one dairy farm situated in a pumped lowland catchment as case studies, this paper explores the feasibility of implementing surface flow constructed wetlands (SFCW.
Subsurface drainage systems that incorporate both controlled drainage and subirrigation (CDSI) can improve crop production, N use efficiency, and reduce possible negative effects on the water quality through reduction of nitrate N entering into surface or groundwater systems (Drury et al., ; Fausey et al., ; Frankenberger et al., ).
The Kirkham streamtube approach is used in the WINDS drainage model, which enables WINDS to model water, salinity, and nitrogen in the soil profile as a function of distance from the drain.
The chapter also includes an example of the economic analysis of drain spacing and depth. Delivery coefficients have long been used in economic analysis of policies that seek to address environmental problems like water pollution.
Subsurface drainage is a beneficial water. Progress 12/23/01 to 12/22/06 Outputs Progress Report Objectives (from AD) Develop and evaluate BMPs that protect surface water quality and enhance crop yields.
Expand efforts to conduct integrated drainage management research and cropping systems research, including watershed modeling and economic assessments, to determine the feasibility for adoption of these BMPs throughout the. Goals / Objectives Determine effectiveness of drainage water management and recycling practices that are integrated in a Wetland Reservoir Subirrigation System (WRSIS) for increasing crop yields and reducing nutrient and sediment loss to streams.

Increased level of NO3-N in the drinking water supplies is a major health concern these days. The long-term effects of actual nitrogen (N) fertilizer management practices are not well understood.
The use of computer models allows the simulation of different N management practices on a long-term basis and their related effects on water quality. The RZWQM (Root Zone Water Quality Model, Version. Agricultural subsurface tile drainage contributes nutrients to Minnesota waters.
Constructed and/or restored wetland systems have proven successful in treating excess sediment and nutrients, especially nitrates, under a variety of conditions and have the potential to improve water quality in Minnesota’s agricultural watersheds.
Because the primary method of transport of nitrate-nitrogen is at the subsurface level, however, tile drainage can significantly hasten its movement to the edge of the field, and, thus, into an adjacent stream.
Jackson et al. found that during a three-year study period, subsurface tile drainage accounted for % of all nitrate losses. An economic analysis shows that the subsurface drainage systems are highly cost-effective: cost–benefit ratios range from tointernal rates of return from 20 to 58%, and the pay-back.
An array of irrigation systems are available which can be broadly classified as being gravity flow or pressurized. Pressurized irrigation systems provide better control on the amount of applied water and, in most cases, better irrigation uniformity than gravity flow systems.
They also have a higher initial capital cost than gravity flow systems and an analysis is required to determine whether. 4 Water Percolation: An Indicator of Nitrogen-Leaching Potential 59 1. WILLIAMS AND D. KISSEL 11 Fate of Nitrate in Subsurface Drainage Waters H.
PIONKE AND R. LOWRANCE and Economic Analysis Package (NLEAP) that was developed to implement xi. xii PREFACE. The RZWQM has been previously used in southern Ontario to assess the long-term effects of nitrogen application rates and timing on nitrate loss in subsurface drainage water under corn production.
Nitrogen from fertilizers may enter streams through surface or subsurface drainage (leaching). Considerable loss of nitrogen may occur if heavy rains immediately follow a surface application of fertilizer on a moist soil surface, particularly in the sloping soils of.
Wherever subsurface drains have been installed to control this groundwater, the drainage effluent has had high nitrate concentrations. Large quantities of inorganic nitrogen fertilizers are applied annually and the assumption prevails that fertilizer is the major source of nitrates in the drainage water.
Improving water and energy efficiency in buildings is one of the best ways to reduce greenhouse gas emissions. This study examines various energy-related carbon dioxide (CO 2) reduction measures, including the use of water efficient showerheads and shower drain water heat recovery, in order to distinguish the significance of user influence on the water usage of a shower.
Goals / Objectives Subsurface tile drains are essential for achieving high crop yields in many regions of the United States, including the humid Midwest and the semi-arid West.
However, tile drains also increase connectivity to surface ditches and streams, thereby providing direct pathways for nitrogen (N) and phosphorus (P) transport to surface water bodies, leading to greater potential for.
The Southwestern United States is facing a water crisis with an extended drought period with water for domestic, industrial, and irrigation use getting scarce every year. Irrigation industry divert the largest amount of water for food production and must take a leading role in achieving a sustainable water use.
The use of microirrigation is one of the ways for the industry to achieve this goal. Simulations were performed for each plot with subsurface drains at m and m. Based on DRAINMOD predictions for the plot 2 through 6, reducing drain depth from to m resulted in 17% reduction in subsurface drainage, 30% increase in surface runoff, and 4% increase in evapotranspiration over an 11 year period.

Lower than expected nitrate removal by the tile-drain bioreactor was likely due to a combination of site/design constraints, potential internal short-circuiting, and water chemistry (% annual N load reduction; g NO3-N removed m-3 d-1, lb N ft-3 d-1).
corn-soybean rotation and spring N application, drainage water management and wetland construction are more economically efficient in reducing N loss, with estimated costs of $ and $ lb-1 N loss reduction, respectively. A % interest rate was used with a and yr life for drainage water management and wetland restoration.
The average concentrations of NH 4 + ─ N, NO 3 − ─ N, and TN were not correlated to drainage discharge according to a Pearson correlation analysis, whereas a power function can quantify the relationship between N mass fluxes and discharge during various water management periods.
