Managing Greenhouse Gas Exchange in a Constructed Wetland Model:
Part 2: The Effects of Peat, Water Content, and NH4NO3 on CO2, CH4, and N2O Emissions
Method
III) NH4 NO3 Addition and Water Sampling
Materials
-12 x 64.5mg of NH4 NO3
-480 mL distilled water (40mL/ container)
-36 water storage containers
-scoopula
-automatic balance
-20 mL pipette
1) Using a pipette, extract water from the substrate of the models and insert into labelled water storage containers.
2) Measure out 64.5 mg of NH4 NO3 using the scoopula and automatic balance. Repeat eight times.
3) Place measured NH4 NO3 concentrations into water storage containers.
4) Add 40mL of distilled water to each container and allow NH4 NO3 to dissolve.
5) Add one 40 mL solution to each model, distributing it as evenly as possible across the surface of the wetlands.
6) Using a pipette, extract water from the substrate of the models and insert into labelled water storage containers.
