Methane uptake of forest soils
Grant number: DP120101735 | Funding period: 2012 - 2015
This project will provide a detailed understanding of capacity of soils in Australia to sequester the greenhouse gas methane. It will identify the main factors and processes controlling methane uptake in soils and improve predictive models will allow us to predict methane uptake in the future.
