“You could look at putting additives in cattle fodder, or something, that reduces methane emissions. You could look at zero-tillage cover cropping, they’re all sorts of other techniques that might be useful. Small tractors, robotics, solar-powered tractors, something to replace nitrogen because nitrogen is a very carbon intensive product. If you can replace that with a kind of different fertilizer, maybe an organic fertilizer, or something like that then the initial emissions would be less.”
