Growth, biomass, carbon storage, and carbon sequestration potential along an age series in Populus deltoides plantations were
assessed. The growth rate of diameter at breast height and height was higher in trees of 4 to 7 years and 2 to 5 years, respectively. The
total aboveground biomass (AGB) increased with age and reached its maximum (180.2 Mg ha–1) at 11 years of age. Mean carbon
concentration in aboveground components varied from 39.7% to 51.7%. Allometric equations were developed to estimate biomass and
biomass carbon in different tree components, which had adjusted R squares greater than 94%. Aboveground carbon stocks in P. deltoides
increased from 0.5 Mg ha–1 at 1 year to 90.1 Mg ha–1 at 11 years. The carbon sequestration rate (i.e. carbon sequestrated in wood products
and by the substitution of biomass for coal) in mature plantations (7–11 years) varied from 5.8 to 6.5 Mg C ha–1 per year. Soil carbon
stocks increased with age (1–11 years) from 61.2 to 66.8 Mg ha–1 and decreased with soil depth. Soil carbon stock in different ages of
plantations varied from 63.9 to 83.8 Mg ha–1 at 0–30 cm depth, 57.5 to 60.1 Mg ha–1 at 30–60 cm depth, and 55.5 to 59.7 Mg ha–1 at 60–90
cm depth. The amount of total carbon stock (AGB and soil) increased from 64.4 Mg ha–1 at 1 year to 173.9 Mg ha–1 at 11 years. This study
recommends P. deltoides planting as a viable option for sustainable production and carbon mitigation.
