Researchers at the Salk Institute are testing genetically edited soybeans with deeper root systems that could help crops survive drought and store more carbon underground. Field trials in Illinois, Missouri, Kansas and Iowa will measure real world carbon storage and yield, with initial results expected this fall. The work is backed by an $18 million grant from the Bezos Earth Fund. Salk estimates one hectare of deeper rooted soybeans could store an extra metric ton of CO2 per year, but that depends on soil conditions and how long the carbon remains below ground. The bigger question is whether farmers and seed companies will adopt the technology quickly enough to matter.
