Boyd Deep Canyon Desert Research Center

09 Jul, 10 AM - 23 Jul, 04 PM

For this 2-week summer campaign, I will deploy a suite of gas analyzers into the plot at Boyd Deep Canyon where soil collars were installed 2 weeks earlier. Instruments include: a CO2 analyzer, a NO and NO2 analyzer, and a N2O isotopic analyzer which also measures N2O and CO emissions, all connected through a multiplexer and 8 automated collection chambers. Because instruments run the risk of overheating, I will be enclosing these instruments in an insulated box with an air conditioning unit. All parts of this suite of instruments will be powered using two gas-powered generators and will be covered with a shade canopy. During the campaign, I will measure trace gas fluxes and soil climate conditions every 30 minutes as they respond to experimental wetting treatments: 1) wetting + N amendment, 2) wetting + C amendment, 3) wetting + C&N amendment, 4) wetting only, 5) rewetting of "wetting only" treatment. I will also collect 3*3*10-cm deep soil cores during prewet and 24 hour post-wet for each treatment; these cores will be processed onsite and then will be transported back to UCR for additional processing and analysis for NH4+, NO3-, total C and N, microbial biomass, pH, and soil moisture.
