Organic phosphorus sequestration in subtropical treatment wetlands.
Diffuse phosphorus pollution is commonly remediated by diverting runoff through treatment wetlands to sequester phosphorus into soil layers. Much of the sequestered phosphorus occurs in organic forms, yet our understanding of its chemical nature is limited. We used NaOH-EDTA extraction and solution 31P NMR spectroscopy to speciate organic phosphorus sequestered in a large treatment wetland (STA...
متن کاملOverestimation of organic phosphorus in wetland soils by alkaline extraction and molybdate colorimetry.
Accurate information on the chemical nature of soil phosphorus is essential for understanding its bioavailability and fate in wetland ecosystems. Solution phosphorus-31 nuclear magnetic resonance (31P NMR) spectroscopy was used to assess the conventional colorimetric procedure for phosphorus speciation in alkaline extracts of organic soils from the Florida Everglades. Molybdate colorimetry mark...
متن کاملPhosphorus dynamics in selected wetlands and streams of the lake Okeechobee Basin *
Lake Okeechobee is becoming increasingly eutrophic, presumably due to P loading from numerous dairy operations in the Lake's northern drainage basin. Phosphorus released from this basin is transported through canals, streams, and wetlands before its discharge into the lake. This paper summarizes the results of several studies on P dynamics in wetlands and stream sediments in the Lake Okeechobee...
متن کاملWetlands and Aquatic Processes Phosphorus Retention by Wetland Soils used for Treated Wastewater Disposal
Wetlands function as buffers for nutrients loaded from terrestrial ecosystems through drainage and surface discharges. The objectives of our study were to (i) determine the P retention capacity of representative wetland soils being used for disposal of treated wastewater and (U) relate P retention characteristics to selected physicochemical properties to evaluate likely mechanisms of P removal ...
