Equations / Aboveground biomass
Mimosa hostilis, caatinga, ground-level diameter
As printed (Table 2, p. 938)
In this library's units, ready to compute (kg)
Aboveground biomass = 0.1064 * DRC^2.2907DRC- Root collar / stem base diameter, cm
Table 2 prints each equation as a*DGL^b or a*DBH^b with the exponent as superscript (flattened here with ^). Biomass is oven-dry aboveground plant biomass in kg (Table 2 title), diameters in cm. Wood dried at 60 C. Plants were cut at the base and the stump was included in the weighed biomass. Perimeters were converted to diameters assuming a circular shape; for branching below measuring height, branch areas were summed into one equivalent diameter. DGL is stem diameter at ground level, mapped to DRC.
