RESEARCH UPDATE No till less gas

Greenhouse gases released into the atmosphere by human industry, such as agriculture, are expected to raise average Australian temperatures by up to 6 degrees over 1990 levels by 2070.

While graingrowing emits a relatively low rate of greenhouse gases per hectare, the industry's size means emissions must be monitored. Agriculture accounts for approximately one-third of Australia's greenhouse gas emissions. The GRDC has invested in greenhouse-related research and the good news is that the low soil disturbance of popular no-tillage farming systems is lessening the release of greenhouse carbon dioxide into the atmosphere.

Greenhouse nitrous oxide release, which results from fertiliser and pulse crop nitrification, remains the subject of ongoing research.
