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
I) Model Setup Process
Materials:
-12 plastic containers
-90 L sphagnum peat moss-soil mixture
- 72L distilled water
-500mL measuring cup
-240 small arrowhead plants
-4 grow lights
1) Place 7.5 L of sphagnum peat moss-soil mixture into each container.
2) Pour 4L of distilled water into Models A1, A2, and A3. Pour 6L of water into models B1, B2 and B3, and also into control models D1, D2, and D3. Pour 8L of water into Models C1, C2 and C3.
3) Plant 20 arrowhead bulbs in each container.
* Due to the setup of the room in which the plants were kept and the position of the grow lights, it was necessary to rotate the models each night.
