Action on the Ground Project

The concentration of greenhouse gases in the atmosphere have significantly increased since the beginning of the Industrial Revolution. The most significant greenhouse gases are carbon dioxide, methane and nitrous oxide with methane and nitrous oxide presenting Global Warming Potentials (GWP) of up to 36 and 298 times higher than carbon dioxide respectively (for a 100-year timescale).
Most nitrous oxide emissions take place in soils and are related to agricultural activities. The research currently underway through the Action on the Ground research project in Monto focusses on gathering and sharing information on how soil management practices like pulse rotations could be used to reduce nitrous oxide emissions.
Following an experimental pulse crop of faba beans last winter, the research team recently harvested the summer rotation of sorghum (the main feed grain crop grown in Queensland). All the mineral nitrogen present in the post-faba harvest soil was as nitrate, which is prone to leaching and loss as nitrous oxide after heavy rainfall.
The project, which is led by Burnett Catchment Care Association, is a collaborative partnership with the BMRG, Central Queensland University, the Queensland Department of Science, Information Technology and Innovation and local growers and is funded by the Australian Government Department of Agriculture and Water Resources Carbon Farming Futures – Action on the Ground program.
