Teco: Carbon Monoxide Consumption By Forest And Agroecosystem Soils, Gary M. King
Teco: Carbon Monoxide Consumption By Forest And Agroecosystem Soils, Gary M. King
University of Maine Office of Research Administration: Grant Reports
Carbon monoxide is a more dynamic component of the atmosphere than methane, occurring at a lower concentration but substantially higher flux. CO and hydroxyl radical interact rapidly, affecting a number of atmospheric parameters: the oxidative state of the troposphere; the fate and residence times of methane, non-methane organics and inorganics; tropospheric ozone; and the extent of thermal forcing. Soils consume atmospheric CO, accounting for 10-25% of the global carbon budget, depending on the source estimate. Some of the controls of soil CO uptake and production have been described generally, but much remains unknown. Details of CO uptake in agroecosystems are …

Lort And Young Rivers Catchment : Catchment Appraisal 2001, Jamie Bowyer, Esperance Catchment Support Team (Wa)
Resource management technical reports
Using the Rapid Catchment Appraisal process, this report summarises current information for the Lort and Young Rivers Catchment, 75 kilometres west of Esperance in Western Australia. The Rapid Catchment Appraisal (RCA) process is one of the processes included in the strategy to tackle salinity and its management in Western Australia. The RCA process provides a 'snap shot' of information on the risk and impact to agricultural production and natural resources within regional geographic catchments.

Potential Runoff Accumulation In Wheatbelt Towns Of Western Australia, Mahtab Ali, Travis Cattlin, Neil Coles, Sharam Sharafi
Potential Runoff Accumulation In Wheatbelt Towns Of Western Australia, Mahtab Ali, Travis Cattlin, Neil Coles, Sharam Sharafi
Resource management technical reports
Describes an analysis of flood runoff volumes from 16 small, gauged catchments in the agricultural areas of south western Australia. It also describes methods for estimating flood runoff volumes from ungauged catchments. The independent variables found to be statistically significant in explaining the variability in flood runoff volumes from the gauged catchments were catchment area, mean annual rainfall and the percentage of the catchment that was cleared. No soil factor was found to be significant.

Monitoring Subsurface Drainage Flow At Remote Locations, Stephen R. Workman, Stephen F. Higgins, Scott A. Shearer
Biosystems and Agricultural Engineering Faculty Publications
Laboratory evaluations and field results are presented for a slotted weir used to measure discharge from subsurface drains. The head–discharge curve for the vertical slot is a simple power function with an exponent of 1.5. There was excellent agreement (r2 > 0.99 and 1:1 slope) between predicted and observed discharge in laboratory testing of 12 test weirs representing five slot widths. The primary advantages of the vertical slot weir are its simplicity, ease of maintenance, and ability to measure small flow rates. Disadvantages include a tendency for the slot to close a small amount over time as a result of …

Island Arcs, Accretionary Terranes And Midcontinent Structure New Understandings Of The Geologic Architecture Of The U.S. Midcontinent, Marvin P. Carlson
Island Arcs, Accretionary Terranes And Midcontinent Structure New Understandings Of The Geologic Architecture Of The U.S. Midcontinent, Marvin P. Carlson
Conservation and Survey Division
A data base collected over the last 100 years, containing both surface and subsurface information, has allowed us to begin to understand the physical framework of Nebraska. We have learned that even in the stable Midcontinent region of North America, there has been an active geologic history. This framework has been deciphered by our programs of surface geologic mapping and by the study of rock samples from both water wells and those deeper test wells for oil and gas. Determining the major structural features across the state (figure 1) has allowed us to better understand both the occurrences of its …
Determining Matric Stress With The Modified Cam Clay Energy Relationship, Richard A. Rohlf, Larry G. Wells
Determining Matric Stress With The Modified Cam Clay Energy Relationship, Richard A. Rohlf, Larry G. Wells
Biosystems and Agricultural Engineering Faculty Publications
The stress generated by matric suction, or matric stress, was determined at points along the stress path with an analytical and experimental procedure based on the modified Cam clay energy relationship. Matric stress was found to be approximately constant at large strain for constant water content triaxial compression tests. Matric stress was included in both shear and volume relationships in a critical–state soil model that employed the modified Cam clay yield function. Shear was modeled with a constant matric stress. Slope of the normal compression and recompression lines was adjusted for matric stress using a state function that expressed matric …
Carbon Dynamics In Peat Bogs: Insights From Substrate Macromolecular Chemistry, Kuder Tomasz, Michael A. Kruge
Carbon Dynamics In Peat Bogs: Insights From Substrate Macromolecular Chemistry, Kuder Tomasz, Michael A. Kruge
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
The macromolecular compositions of subfossil plants from boreal Sphagnum bogs and restiad bogs (New Zealand) have been studied by pyrolysis-gas chromatography/mass spectrometry to evaluate the extent of degradation in the anoxic zone (catotelm) of a peat bog. Degradation of vascular plant polysaccharides was apparent only into the upper catotelm. Sphagnum was degraded more slowly than vascular plants, but no cessation of degradation was observed. The inferred rate of degradation varied depending on type of plant, extent of aerobic, precatotelmic degradation, and mode of litter deposition (rooting versus at the surface). Environmental forcing on anaerobic carbon dynamics would potentially be largest …

Application Of Neuro-Fuzzy Technique+2:9s To Predict Ground Water Vulnerability In Northwest Arkansas, B. Dixon, H. D. Scott, J. V. Brahana, A. Mauromoustakos
Technical Reports
Contamination of ground water has been a major concern in recent years of local, state and federal agencies involved with the management, quality, and quantity of water and their relationships with human health. The Springfield Plateau aquifer, which lies beneath the study area in northwest Arkansas, has been shown to have higher nitrate-N (NO3-N) concentrations than the national median. The dominant landuse (LULC) of this area is agriculture (primarily pasture/cattle and woodlands) and an encroaching urbanization. The major sources of nitrogen in the study area are poultry/cattle wastes, inorganic fertilizers (Peterson et. al., 1998) and septic filter fields. Many of …
