..." Soils under long-established prairie grasslands can contain more than 10 tons of roots per acre with most of this bulk in the top 24 inches.
......The roots of some prairie plants can extend to a depth of 10 feet or more. Various studies of the potential for tallgrass prairie carbon storage have shown that the storage rates vary between .30 and 1.7 metric tons per acre per year. This storage ability is cumulative over time so prairie soil is able to sequester or store large volumes of carbon in a natural, safe, effective and reliable way compared to the risky and expensive practice of pumping CO2 underground.
An additional benefit of this “grassland carbon storage system” is that the sequestered carbon is supporting a lush prairie ecosystem above ground. "...
