The statement describes coal-to-natural-gas conversion followed by fertilizer production in the U.S. heartland. While coal can be converted to syngas (which contains hydrogen and can be used to produce ammonia for fertilizer), this is not a common or economically dominant pathway in the U.S. today; most U.S. fertilizer production uses natural gas directly (from shale) rather than coal-derived gas. Large-scale coal-to-fertilizer plants in the heartland are not a major current reality, making the statement misleading in its implication that this is a widespread or primary domestic method.

While the Great Plains Synfuels Plant in North Dakota does convert coal to synthetic natural gas, there is no known facility that uses that gas to produce fertilizer locally; the statement implies a coal-to-gas-to-fertilizer process that is not currently operational in the U.S. heartland.

U.S. fertilizer production primarily uses natural gas extracted directly, not coal that is first converted to natural gas; coal‑to‑gas facilities are rare and not a major source for domestic fertilizer, making the claim misleading.
