- A trial on a vineyard near Auburn in South Australia has been trying to produce nitrogen fertiliser using "lightning" in a bottle
- Development of non-thermal plasma unit technology could help farmers produce their own nitrogen fertiliser
- If powered using solar panels it could be a green option for fertiliser production
"If you imagine having an arc welder in a beaker of water, and then feeding air past it, it's effectively mimicking lightning in a very controlled fashion,"he said.
"As all farmers know urea is extremely expensive, so I think it's going to be a really good option."
