OC stock in bulk soil(kg/m2)=
OC × SBD × D / 100, 就是这个转换系数我看有的是×10, 有的又是➗10。SOC stocks单位一般都是Mg/ha.
这是我另外看的文献公式:Estimation of Soil Organic Carbon Stock Total SOC stock of profile for each of the five depths (0–20, 20–
40, 40–60, 60–80, 80–100 cm) was computed by multiplying the SOC concentration by the bulk density, depth, and factor by 10
(Equation 1). Profile SOC stock=SOC concentration(g/kg)× bulk density(Mg/m3)×depth(m)×10
SOC stock was calculated according to Shofiyati et al.
(2010), which is given as below: SOC stock(t/ha)
=TOC(g/kg) × BD (g/cm3) × soil depth(m) × 10 4× m2/ha ×10
