Caption: MODEL RELEASED. Plant greenhouse gas research. Technician (left) and soil scientist (right) using gas chromatography to determine the amount of greenhouse gases in plant samples collected from a farm. Agricultural practices, particularly the use of nitrogen-based fertilisers, generate significant levels of the greenhouse gases nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4). This research is being done to determine the mechanisms behind these emissions.
