Nitrate reduction rates and soil/ water chemistry from roadside ditches in the Mobile Bay (AL, USA) region (2018-05-23 to 2018-06-08) (NCEI Accession 0211099)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 03:40 AM | Dataset Last Updated: July 15, 2020 at 12:00 AM
Ninety-six roadside ditches spanning three landuse types in the Mobile Bay (Alabama, USA) region were sampled in May-June of 2018. Isotope pairing was used to measure nitrate reduction rates (denitrification, anammox, and dissimilatory nitrate reduction to ammonium) on soil slurries. These values were used to calculate the percentage of nitrogen removed in ditch soils. Soil extractable nitrate and ammonium, organic matter content, and plant above/ belowground biomass were measured as well. There was standing water in seventeen of the ditches and it was measured for nitrite, nitrate, ammonium, and phosphate concentrations.
