陆地生态系统碳储量（1m）---3170Pg

土壤总碳储量 ---2550Pg (organic C---1550Pg; inorganic C---950Pg)

biochar remove GHG potential---1-1.8 Pg CO2-C per year

Rattan Lal 2018 GCB Digging deeper: A holistic perspective of factors affecting soil organic carbon sequestration in agroecosystems

The global magnitude (Pg) of soil organic carbon (SOC) is 677 to 0.3-m, 993 to 0.5-m, and 1,505 to 1-m depth. Thus, ~55% of SOC to 1-m lies below 0.3-m depth.

Esteban G. Jobbágy 2000 EA THE VERTICAL DISTRIBUTION OF SOIL ORGANIC CARBON AND ITS RELATION TO CLIMATE AND VEGETATION

土壤总SOC储量 -(0-3m): --2344Pg.

Global totals for the 0-1m: 1502 Pg estimated for the first meter (which is similar to the total SOC estimates of 1500–1600 Pg made by other researchers).

1-2 m and 2-3 m were 491 and 351 Pg C
