Can rotational grazing sequester all our CO2 emission?

The "mob, mow, and move" strategy of rotated grazing of livestock implemented by Allan Savory and Joel Salatin has been peer-reviewed.

The bottom line? North America could sequester about 1.2 Gigatons of Carbon a year. Multiply by 3.67 to convert to CO2, and that's 4.4 Gigatons of CO2, or 1/8th of the 36 Gigatons CO2 we release each year.
So we need 8 times the pastureland to sequester all our CO2. The USA has 2.38 million km2 under permanent pastures in 2008.

The world has 35. That's 14 times the pastureland of the USA, or 1.8 times the land necessary to sequester all our CO2.
