Demonstration projects for on-farm practical methane management strategies: Trevenna
The ‘Trevenna’ on farm demonstration site in collaboration with MLA and the Australian Government’s Climate Change Research Program - RELP was set up to build an integrated reference data of all major carbon flows in current and potential future sheep grazing systems (soil, animal, plant, air). Farmers, scientists, and students have participated in 49 events in the last 2 years, with over 2,000 people hearing about the project and over 550 people visiting the ‘Trevenna’ site. This project demonstrated how to estimate methane (CH4) emissions and practical management for reducing emissions intensity. The FTIR spectrometer estimate of CH4 emissions were 19.5 and 17.5 g CH4/animal/day on high (HPL) and low productivity landscapes (LPL), respectively. Nitrous oxide emissions (N20) were 4 times higher on the HPL than the LPL 20 v. 5 μg N2O/m2/h in autumn, but 13 times higher on HPL in winter when the C4 plant species was dormant on the LPL.
