CAN WE USE WETLANDS TO TREAT PULSES OF NUTRIENTS FROM AGRICULTURAL WATERSHEDS?
Agricultural production has been identified as a major source of nutrients contributing to the eutrophication of aquatic ecosystems throughout the world. Among the practices implemented to reduce the mass of nutrients reaching sensitive water bodies is directing agricultural runoff or drainage through wetlands. The natural biogeochemial processes that occur in wetlands appear to make them an ideal treatment system for excess nutrients. The wetlands used for the treatment of agricultural non-point source pollution can take multiple forms, including restored wetlands or wetlands built solely for treatment.
Nutrient export from row crop agriculture generally occurs in pulses that is driven by rainfall events. These short periods of high nutrient flux are different from the nutrient dynamics found in other treatment wetlands that operate closer to a steady state. For wetlands to be effective sinks for nutrients from agricultural production, the processes that retain nutrients must be capable of reacting quickly to the arrival of a pulse of nutrients. This presentation will examine the effectiveness of wetlands to remove nutrients in agricultural watersheds.
