Project Number: 6408-13660-004-03
Project Type: Specific C/A

Start Date: Sep 28, 2001
End Date: Sep 14, 2006

Objective:
Document the effects of carbon and landscape position on denitrifications resulting from the implementation of different intensities and types of best management practices in a Management System Evaluation Area (MSEA). Examine the relationships between quality of agriculture runoff, organic carbon and environmental improvement as a result of management practices.

Approach:
Potential and laboratory rates of Delta soil denitrification as related to crop type and landscape position will be determined. Sites will be selected for the measurement of soil denitrification in the Mississippi Delta MSEA Project. Site selection will include paired agricultural and riparian zone land uses with three replicates of each. At each plot, autorecording water wells will be installed and data downloaded at least quarterly. At each plot, autorecording water wells will be installed and data downloaded at least quarterly. At each of these sites, intact soil cores will be sampled seasonally and transported to the laboratory for the determination of denitrification. Denitrification enzyme assay will be used to measure the potential denitrification rate and is equivalent to the Phase I assay.
