Agricultural biogeochemistry
research area
Ongoing and historical data available for the Harford Animal Science Teaching and Research Center (some for 25-30 years):
- Water quality from 15 wells, including nitrate
- Soil test results (pH, P, potassium, and N availability) and crop yields
- Manure and fertilizer applications: good records for 20 years
- Nutrient inputs via animal feed
- Animal densities
- Field management
Data to be collected for this project:
- Repair and sample wells monthly for a year; analyze DON, nitrate, ammonium
- Monthly + storm event surface samples from drainage creeks and nearby streams; analyze for sediments, nitrite, nitrate, ammonium, TDN, SRP, TDP, and particulate N and P
- Monitor deposition of ammonia and ammonium along gradients away from the farm site, using both bulk deposition measurements (Fahey et al. 1999) and passive samplers for ammonia gas in the atmosphere.
