The contracts Gevo is developing with corn growers in South Dakota are intended to keep carbon in the ground by reducing the use of commercial fertilizer, increasing soil fertility and reducing erosion.

About 90% of nitrate contamination comes from manure and commercial fertilizer application.

As of March, commercial fertilizer prices reached a record high, with nitrogen fertilizer jumping four-fold since 2020 and phosphate and potash up three-fold, said London-based consultancy CRU Group.

Even in states where large livestock herds generate massive quantities of manure, there's not enough to replace commercial fertilizer completely.

"If I sold any more, I'd have to turn around and buy commercial fertilizer, which makes no sense," Reisinger said.
