Which fertilizers are those? I was under the impression that nitrogen fertilizers were by far the most important. We get the nitrogen from the sea of it that we're swimming in -- no need to dig it out of the ground. The Haber process also uses hydrogen, which probably comes from WGSR, is that what you mean? If so, I strongly suspect that fertilizer production necessary for human survival would easily be economical on electrolytic hydrogen.
