80% of a prairie’s biomass is below ground, which is a part of the reason why prairies are the greatest soil carbon factories in the world. Those roots break up compacted soil, and as a portion of those roots die each year, they add organic matter and decompose into carbon, further enriching the soil; all of this is done without deadly pesticides or equally deadly petrochemical fertilizers needed to keep the 41 million acres of lawn in US going.
