Denitrification in Surface Soils of a Riparian Forest: Effects of Water, Nitrate and Sucrose Additions
We studied the effects of adding water, nitrate and sucrose on denitrification in a riparian forest that receives nitrate in drainage from cornfields. We used large (3-6 m2) flow-through chambers to sample N 2 0 emissions from surface soils. N2 emissions were estimated by comparing N 2 0 efflux in chambers with or without acetylene addition. Water and solutions of nitrate or sucrose were sprink...
متن کاملDenitrification in riparian forests receiving agricultural discharges
Riparian forests can remove large amounts of nitrate from the groundwater discharges of adjacent uphill croplands. We review the mechanisms that could account for NO3 removal. Denitrification is hypothesized to be important, but measurement problems limit the relevant field data. We used large chambers (1-20 mZ) and tunable-diode laser infrared spectrophotometry to measure nitrous oxide (NzO) e...
متن کاملUnderstanding the Science Behind Riparian Forest Buffers: Factors Influencing Adoption
The riparian area is that area of land located immediately adjacent to streams, lakes, or other surface waters. Some would describe it as the floodplain. The boundary of the riparian area and the ad join ing uplands is gradual and not always well defined. However, riparian areas differ from the uplands because of their high levels of soil moisture, frequent flooding, and unique assemblage of pl...
متن کاملMicrobial Nitrate Processing in Shallow Groundwater in a Riparian Forest
We measured denitrification, immobilization, and respiration in microcosms that simulated groundwater conditions in a riparian forest in Rhode Island. Measured rates were compared with rates of NOj" removal measured in a companion study using a groundwater monitoring well network and 10-mo injection of NOf and a bromide tracer to groundwater in the same riparian forest. Limiting factors for den...
متن کاملEvaluating the quality of riparian forest vegetation: the Riparian Forest Evaluation (RFV) index
Aim of study: This paper presents a novel index, the Riparian Forest Evaluation (RFV) index, for assessing the ecological condition of riparian forests. The status of riparian ecosystems has global importance due to the ecological and social benefits and services they provide. The initiation of the European Water Framework Directive (2000/60/CE) requires the assessment of the hydromorphological...
