Ninety-six roadside ditches in the Mobile Bay region of Alabama, USA, were sampled to measure nitrate reduction processes and soil/water chemistry. Data includes denitrification, anammox, and dissimilatory nitrate reduction to ammonium rates, soil extractable nutrients, organic matter, and plant biomass. The dataset was collected by NOAA_NCEI from May to June 2018.
Use Cases
- Predict percentage of nitrogen removed in ditch soils using measured nitrate reduction rates and soil organic matter content.
- Model relationships between landuse type and concentrations of nitrite, nitrate, ammonium, or phosphate in standing water from 17 ditches.
- Analyze correlations between plant above/belowground biomass and soil extractable nitrate or ammonium levels.
- Compare denitrification, anammox, and dissimilatory nitrate reduction to ammonium rates across different soil chemistry conditions.
Strengths
- Samples from 96 distinct roadside ditch sites provide spatial coverage.
- Measures multiple nitrate reduction pathways (denitrification, anammox, DNRA) and key soil/water chemistry parameters.
- Data collection occurred over a focused 17-day period in May-June 2018, ensuring temporal consistency.
Limitations
- Sample size for water chemistry is limited to the 17 ditches with standing water.
- Temporal scope is narrow, representing only a single snapshot in late spring 2018.
- Unknown row count and file structure limit assessment of dataset volume and granularity.
