Preliminary Study “An overview of nitrate and nitrite concentrations in soil from the Meadowlands".

“Nitrous oxide is the world’s third largest greenhouse gas
which, in high concentrations, can negatively affect both plant and animal
health.  It is released into the atmosphere by a process known as the
Nitrogen Cycle. This is a natural process where nitrogen is reduced with
hydrogen to yield ammonia, a form of nitrogen commonly used by most living
species to synthesize proteins, nucleic acids and other nitrogen containing
compounds.  The residual nitrogen is then converted into nitrous oxide
mostly by bacteria found in both soil and plant roots. This presentation is
based on a preliminary study for larger research concerning the ratio of
nitrogen ions and nitrous oxide in the marsh ecosystem of the Meadowlands
region. Sediment from eight various sites have been sampled twice in a two week
period and analyzed for anions, mainly nitrate and nitrite. Two sites with the
highest total nitrate + nitrite concentration , one landfill and one naturally
occurring wetland, will be selected and sampled repeatedly next year for both
nitrous oxide concentrations and soil.  The data will be analyzed to
explore 1) the impact of varying levels of nitrate concentrations in soil and
their relationship to nitrous oxide, 2) how this relationship differs between a
landfill site and a man-made wetland, and 3)  the seasonal impact  on
nitrous oxide admission.”
