The Distribution and Function of Denitrification Genes: Exploring Agricultural Management and Soil Chemical Implications
Title of thesis: THE DISTRIBUTION AND FUNCTION OF DENITRIFICATION GENES: EXPLORING AGRICULTURAL MANAGEMENT AND SOIL CHEMICAL IMPLICATIONS Holly Bowen, Masters of Science, 2016 Thesis directed by: Professor Stephanie Yarwood Department of Environmental Science and Technology Denitrification is a microbially-mediated process that converts nitrate (NO3) to dinitrogen (N2) gas and has implications ...
متن کاملIn situ ground water denitrification in stratified, permeable soils underlying riparian wetlands.
The ground water denitrification capacity of riparian zones in deep soils, where substantial ground water can flow through low-gradient stratified sediments, may affect watershed nitrogen export. We hypothesized that the vertical pattern of ground water denitrification in riparian hydric soils varies with geomorphic setting and follows expected subsurface carbon distribution (i.e., abrupt decli...
متن کاملPersistence of denitrifying enzyme activity in dried soils.
The effects of air drying soil on denitrifying enzyme activity, denitrifier numbers, and rates of N gas loss from soil cores were measured. Only 29 and 16% of the initial denitrifying enzyme activity in fresh, near field capacity samples of Maury and Donerail soils, respectively, were lost after 7 days of air drying. The denitrifying activity of bacteria added to soil and activity recently form...
متن کاملChanges in Denitrification Rate, Bacterial Denitrifier Community Structure and Abundance in Dairy-grazed Pasture Soils Treated with Cattle Urine and Dcd
Urine excreted by cattle can produce very high concentrations of available N in relatively small volumes of soil and lead to high nitrous oxide (N2O) emissions. Application of the nitrification inhibitor dicyandiamide (DCD) can inhibit nitrification. DCD application results in lower nitrate (NO3 ) concentrations and N2O emissions from denitrification in urine affected soils. However, the effect...
متن کاملDetection and Diversity of Fungal Nitric Oxide Reductase Genes (p450nor) in Agricultural Soils.
UNLABELLED Members of the Fungi convert nitrate (NO3 (-)) and nitrite (NO2 (-)) to gaseous nitrous oxide (N2O) (denitrification), but the fungal contributions to N loss from soil remain uncertain. Cultivation-based methodologies that include antibiotics to selectively assess fungal activities have limitations, and complementary molecular approaches to assign denitrification potential to fungi a...
