Industrial Pyrolitic Bioenergy, (If one leading char company, Cool Planet makes your car into an air cleaning appliance with Bio-Gasoline & Char, add 1/2 GtC); 2 GtC
Holistic Grazing; (aka, Mob Grazing, Intensive Paddock Management, and given the 2012 UGA study showing 3.5 Tons C/Ac/am, potential could be twice this), 2+ GtC
Over 6 GtC,
So soils & biota can do more than half the 10 GtC reduction job, feeding carbon to life instead of death.

Erich is right that there is no doubt that the increased growth and storage of biomass above ground, biomass below ground, and of soil organic carbon (not including elemental black carbon) should all increase with biochar addition, some very considerably, but that the multiplier will vary with intrinsic soil fertility and climate, so that there is no single multiplier for all habitats and ecosystems, but many that must be determined experimentally. No matter how you slice it, it will be way ahead of BECCS!
The table you cite shows a lot that people are still confused comparing ocean and land carbon cycles. Not only is terrestrial biomass much higher than marine biomass, but it also captures far more carbon despite the much faster growth rate of algae than trees. In fact when you compare productivity on a unit area basis, the land is capturing around twice as much CO2 as the ocean, even though the latter is nearly 5 times larger in area, so carbon sequestration on land is potentially up to 10 times greater per unit area.
The point of my 1987 Nature letter on The Other Side of the Global CO2 Problem (expanded in later papers) was that rapid cycling on land, and restoration of tropical biomass and soil carbon in particular, could prevent CO2 and climate overshoot in as little as decades, while the ocean takes 1600 years to turn over its dissolved inorganic carbon, and longer for dissolved organic carbon, based on C-14 age measurements. That 1987 Nature paper led to Richard Grantham calling me and asking me to join him planning the First Geotherapy Conference in Lyon.

<PastedGraphic-6.tiff>
The final column seems to include carbon both above and in the ground. It must exclude inorganic carbon.
I was surprised to see that for land vs ocean the total GPP ratio (in Gt C/yr) was about 2:1 (115/55), but the global biomass (Gt C) itself about 470:1 (1837/3.9). The ratio of these important fundamental global parameters is more than 300:1. I bring up ocean biomass as I think we will need it for soil improvement; algal beds show up as good as tropical rain forests on a per unit area GPP basis.
Anyone know of a better such table? (Wanting to separate out above and below ground carbon.)
