*The Haber-Bosch process can fix nitrogen directly from the atmosphere.It does require heat,but that could come from renewable energy.
*Farm equipment could be electrified.The present,water-filled ballasted tires could become the batteries.

*Mining can be electrified.Some of it already is.
*Phosphorous IS an issue.Regardless of climate change.
