Summary: This paper reports one of the highest carbon drawdown rates ever documented – 8 tons per hectare (3.2 tons per acre) per year. The high C capture in soil occurs through a conversion from row cropping to “management-intensive grazing.” Cation exchange and water holding capacity also increased by 95% and 34%, respectively. The study was conducted on farms in Georgia, USA, where the average annual precipitation is 1,224 millimeters (48 inches).
