...where does the fertiliser come from?

Currently, there's a lot of fossil fuels involved.

Ammonia created from fossil fuels accounts for 2% of carbon emmisions, but it seems likely that ammonia created from air and water with renewable energy will replace it in the future. Theres some pilot plants in existance.
