Anaerobic Dissipation of Herbicides in Microbiologically Induced Soil Redox Regimes
… may encounter anaerobiosis as a result of soil flooding, poor drainage, or offsite transport. Anaerobic dissipation of herbicides in the environment is poorly understood. The objective of this research was to characterize the anaerobic fates of herbicides atrazine, trifluralin, and …

The Influence of Hydrogeomorphology, Soil Redox Conditions, and Salinity on the Spatial Zoning of Saltgrass, Salt Rush, and Cattails in Scotts Creek Marsh, Swanton Pacific Ranch, CA
… the effectiveness of Indicator of Reduction in Soil (IRIS) tubes to indicate the reduction of S. The study examined the following parameters from April 6 to July 21, 2013: (i) the HGM of Scotts Creek Marsh, (ii) soil oxidation and reduction (redox) conditions, (iii) salinity, and (iii) the …

Correlation Analyses among Soil, Plant, and Environmental Variables and Greenhouse Gas Emissions from Furrow-irrigated Rice on a Silt-loam Soil
… (VWC), temperature, and oxidation-reduction (redox) potential. No research has been conducted to relate greenhouse gas (GHG) production to soil and plant properties or environmental factors under furrow-irrigated rice. The objective of this field study was to evaluate correlations between …

An assessment of the potential for in situ preservation of buried organic archaeological remains at Sutton Common, South Yorkshire
… factors; these being hydrological monitoring, soil redox monitoring and microbiological assessment. The most crucial of these, and the one that has been the focus of the monitoring effort, has been the hydrological monitoring as this is essential at identifying saturated conditions, which are …

Bioavailability of metolachlor and glyphosate in aerobic and anaerobic soils
… prevalence of anaerobic wet situations in the soil, the predictive capability for the environmental fate and bioavailability of these herbicides is based primarily on well-drained soil conditions. Anoxic events and flooding ubiquitous to agroecosystems may pose a threat for persistence and …

Historical and contemporary drivers of greenhouse gas emissions from upland soils
… that can feed back on climate change by altering soil greenhouse gas (GHG) emissions. Ponding of soils can temporarily decrease soil O2 concentrations, creating conditions conducive for anaerobic biogeochemical reactions that produce and consume nitrous oxide (N2O) and carbon dioxide (CO2). In …
