Abstract

This study was conducted to determine methane emission rates from wetland rice in tropical regions of West Java, Indonesia, and the effect of various irrigation and water management practices and of rice varieties on the emissions. The experiment tested three water management treatments (continuous flooding, intermittent irrigation, and saturated soil conditions) and three rice variety treatments (unplanted, planted with IR-64, and planted with Cisadane rice) using a split-plot experimental design with three replicates. Methane fluxes were observed during the entire growing period three times per day, one day per week, using a static chamber technique. The results of this study revealed that both water management treatments and rice varieties significantly affected diurnal and seasonal variations of methane flux from wetland rice. Rice with continuously flooded irrigation regimes and intermittent irrigation showed that methane fluxes were 1.4 - 1.9 times higher in the afternoon compared to predawn sampling; however, a reverse phenomenon was observed under saturated soil conditions. The diurnal methane flux variations observed in this study were most likely due to an average difference of 5 degrees C in soil temperature at 5-cm depth between predawn and afternoon.

Methane and CO2 chamber fluxes and porewater concentrations US-OWC Ameriflux wetland site, 2015-2018

Dataset Bohrer, Gil ; Ju, Yang ; Arend, Kristin ; ...

The data measurements of CH4 and CO2 at different patch types (classified by dominant macrophyte vegetation or hydrological state). CH4 and CO2 data include 3 types of measurements: 1) Surface flux measurements from chamber measurements. 2) Leaf flux measurements from plant chambers, providing the rate per leaf area of methane flow through three species of macropyte aerenchemous plants (Water Lily, American Lotus, and Cattail) with the corresponding flux of CO2 at the same leaves. 3) Pore water concentrations of dissolved CO2 and CH4 concentrations. These are measured along vertical profiles at varying depths from the soil-water interface using in-situ porewatermore »« less

Abstract:Freshwater wetland soils are foci of biogeochemical cycling as they serve as key sources of methane to the atmosphere. An array of metalloenzymes is essential to anaerobic microbial carbon transformations. Nickel is notably recognized as playing key roles in the enzymatic pathways of methanogenesis. Low availability of trace metals limits microbial element cycling in laboratory studies, but the occurrence of such limitations in natural subsurface aquatic systems is poorly understood. Microcosm incubation studies were carried out using two distinct wetland soils, one from a marsh wetland and the second from a riparian wetland, to explore the effect of dissolved Nimore »« less
Trace Metal Content and Speciation, Water and Soil Chemistry, and Methane Production for a Wetland in Missouri (September 2015) and in Florida (January 2016)

Dataset Catalano, Jeffrey G ; Cromptom, Nyssa M ; Hasenmueller, Elizabeth A ; ...

Data is associated with a manuscript in preparation for submission to explore whether low trace metal availability inhibits methane production in freshwater wetland soils. Reported data are from two field sites, one in Missouri and the second in Florida (see location data). At each site, surface water compositions and properties and soil compositions are reported. Trace metal availability is assessed via sequential chemical extractions, Ni K-edge X-ray absorption near edge structure (XANES) spectroscopy, and X-ray microfluorescence imaging. Soil mineralogy is determined via powder X-ray diffraction. Multi-energy X-ray microfluorescence imaging as well as bulk and microscale S K-edge XANES spectra assessmore »« less
