There are 3 elements that are required for high yield on crops: nitrogen, potassium, and phosphorous.

Nitrogen (in molecules usable by plants) was traditionally the bottleneck, the limiting factor, until the development of the Haber Bosch process, which allows plentiful atmospheric nitrogen to be combined with hydrogen and energy to make ammonia.

Creating green hydrogen (by cracking H2O/water into hydrogen and oxygen molecules using electrolysis) allows for the process to generate ammonia without contributing carbon to the atmosphere. That means it doesn't actually need plants or any biological feedstock for the process. Nitrogen can be fixed into the soil without plants (or fossil fuels), so that part isn't going to be the limiting factor.

I'd be much more concerned about the sources of mined potassium/potash and phosphorus/phosphates.

Potassium is from Canada. That country just thrown in a trade war. Yeah, that might worry some farmers.
