it is possible, but requires continuing disruption to the nitrogen cycle to artificially fix nitrogen which has some potential long term ecological consequences. the haber-bosch process used natural gas to produce ammonia, so we need to modernize it to use electricity as the energy source for nitrogen fixation. mineral depletion of soil is also an issue, although probably not an insurmountable one.

it’s a whole lot easier to do all of this if we properly address climate change.
