UCNRS RAMS

We will take greenhouse gas flux measurements to characterize the seasonal variability of the flux rates. Field samples will be taken bimonthly from early April 2019 to May 2020 at each plot. These samples will be taken to characterize the GHG fluxes and environmental conditions of the saturated (Dec-Feb), moist (Mar-May), and dry seasons (Jun-Nov). The soil GHG fluxes will be measured using a static dark chamber technique. The aluminum chamber bases (0.076 m2 ) will be inserted approximately 20 cm into the soils at least one week before the first measurement to allow the soil to equilibrate. The bases will not be moved throughout the duration of the study. At the time of sampling, the moat on the top of the chamber base will be filled with water before placing the chamber top to create an air tight seal. Gas samples will be collected between 10 am-3 pm local time to control for the effect of temperature on microbial activity. Chamber headspace samples will be taken using syringes immediately after each chamber is sealed and approximately 15, 30, and 45 minutes after the initial sample. The samples will be taken to the laboratory to be analyzed within 24 hours on a gas chromatograph. Ambient air samples will also be collected at the final sample at each chamber is taken. The following ancillary data will be collected next to each chamber once per sampling date: air temperature, soil temperature, salinity, redox potential, soil moisture, and soil concentrations of NO3 - and NH4 + . Soil organic matter content and pH will be taken once per season. Air temperature and soil temperature will be measured using temperature probes Soil samples will be collected and analyzed in the laboratory for soil salinity, soil pH, NO3 - and NH4 + soil concentrations, and soil organic matter content using a 1:5 soil slurry method for salinity and pH, KCl extraction for soil N, and loss on ignition (LOI) technique for soil organic matter, respectively.
