Reconnecting tile drainage to riparian buffer hydrology for enhanced nitrate removal.
Riparian buffers are a proven practice for removing NO from overland flow and shallow groundwater. However, in landscapes with artificial subsurface (tile) drainage, most of the subsurface flow leaving fields is passed through the buffers in drainage pipes, leaving little opportunity for NO removal. We investigated the feasibility of re-routing a fraction of field tile drainage as subsurface fl...
متن کاملSelenium Removal from Agricultural Drainage Water: Lab Scale Studies
This report is an evaluation of the selenium removal from agricultural drainage water and synthetic solutions contaminated with high amounts of selenium. Batch and kinetic studies were conducted on the removal of selenium and the effectiveness of various remediation materials was determined. The agricultural drainage water samples were obtained from San Joaquin Valley and provided by Department...
متن کاملPhosphorus losses through agricultural tile drainage in Nova Scotia, Canada.
Tile drainage water from agricultural fields commonly exceeds environmental guidelines for phosphorus (P) in rivers and streams. The loss of P through artificial drainage is spatially and temporally variable, and is related to local factors. This study characterizes variability in total P (TP) and soluble reactive P (SRP) concentrations in weekly drainage samples from 39 agricultural fields in ...
متن کاملEffectiveness of Constructed Wetlands in Reducing Nitrogen and Phosphorus Export from Agricultural Tile Drainage
nutrient in estuaries. Phosphorus enters surface waters in both dissolved and particulate form and is generally Much of the nonpoint N and P entering surface waters of the the limiting nutrient in lakes. A large portion of the N Midwest is from agriculture. We determined if constructed wedands could be used to reduce nonpoint N and P exports from agricultural and P now entering U.S. freshwater ...
متن کاملNitrogen removal and greenhouse gas emissions from constructed wetlands receiving tile drainage water.
Loss of nitrate from agricultural lands to surface waters is an important issue, especially in areas that are extensively tile drained. To reduce these losses, a wide range of in-field and edge-of-field practices have been proposed, including constructed wetlands. We re-evaluated constructed wetlands established in 1994 that were previously studied for their effectiveness in removing nitrate fr...
