Belowground Contributions of Pea and Canola to Soil Nitrogen Pools and Processes
… was uncoupled from rhizodeposition and denitrification enzyme activity (DEA), root-derived 15N correlated with DEA in pea and canola. This research highlights the importance of belowground inputs from differing crop species on N budgets and soil N cycling.

A Process-Based Nutrient Model for the Bedded Manure Pack of Confined Beef Systems
… total potassium), short-term nitrification activity potential, and denitrification enzyme activity from simulated beef cattle bedded manure packs related to storage length (0 to 3, 3 to 6, and 6 to 9 weeks), bedding material (corn stover or soybean stubble), and temperature (10°C or 40°C). …

Legacy Effects of Long-term Manure Applications on Soil-derived Nitrous Oxide Emissions
… (i.e., from May 2011 to June 2014). In addition, denitrification enzyme activity (DEA) was measured in a subset of the plots starting in June 2011 and continuing three times per year (i.e., prior to and after the spring fertilizer application and again in early fall). Treatment-induced N2O …

Method development and application for measuring representative & potential denitrification rates during wastewater reclamation in soil treatment units
… units has identified the large variability in denitrification rates as a major obstacle. A method for quantifying representative and potential rates of denitrification in soil subject to wastewater application was developed and implemented. Four columns were packed with soil classified as …

Denitrification response to nutrient enrichment in New Zealand estuaries
… organic-rich sediments. Nutrient processing and denitrification in estuarine sediments represent important ecosystem functions regenerating nutrients for primary producers, and regulating the ability to remove excess terrestrially derived nitrogen. Denitrification therefore offers resilience to …
