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)

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.
