Hydrological variability and agricultural drainage ditch inorganic nitrogen reduction capacity.
The application of inorganic nitrogen fertilizers on agricultural landscapes has the potential to generate concerns of environmental degradation at fine to coarse scales across the catchment and landscape. Inorganic nitrogen species (NO3*, NO2*, and NH3) are typically associated with subsurface flow processes; however, surface runoff from rainfall events in no-till agriculture with inorganic su...
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 کاملRelease rates and potential fates of nitrogen and phosphorus from sediments in a eutrophic reservoir
1. Nutrients released from lake sediments can influence water column nutrient concentrations and planktonic productivity. We examined sediment nutrient release [soluble reactive phosphorus (SRP) and ammonia (NH4 )] at two sites in a eutrophic reservoir (Acton Lake, OH, U.S.A.) that differed in physical mixing conditions (a thermally stratified and an unstratified site). 2. Sediment nutrient rel...
متن کاملAcceleration of selenium volatilization in seleniferous agricultural drainage sediments amended with methionine and casein.
Phytoremediation is potentially effective for managing excessive selenium (Se) in drainage sediment residing in the San Luis Drain in central California. This 2-year field study examined the feasibility of amending drainage sediment (containing 4.78microgSeg(-1)) with methionine and casein to enhance volatilization without or with vegetation of Sporobolus airoides. Results show that without org...
متن کاملRelease of multiple bubbles from cohesive sediments
[1] Methane is a strong greenhouse gas, and marine and wetland sediments constitute significant sources to the atmosphere. This flux is dominated by the release of bubbles, and quantitative prediction of this bubble flux has been elusive because of the lack of a mechanistic model. Our previous work has shown that sediments behave as elastic fracturing solids during bubble growth and rise. We no...
