Forests are regarded as an economically viable solution to reduce greenhouse gas emissions and mitigate climate change. Carbon sequestration in forests is accomplished through surface and underground biomass as well as soil, which are interconnected and important sources of carbon storage. using direct calculations based on stem analysis and plant biomass. Four poplar plantations were selected, and a one-hectare plot was sampled in each plantation. DBH and the total height of all trees were measured in each plot, and two poplar trees were randomly selected and cut for analysis. Stem analysis, wood biomass determination, and carbon measurement were conducted. In each plot, soil profiles were dug, and samples were taken to measure the physicochemical properties. The results showed that Shaft had the highest density (N/ha) (326), followed by Siahkal (216), Langrud (129), and Talesh (190), respectively. Stand tree stem carbon content (tons per hectare) was the highest in Talesh with 52 tons per hectare, followed by Shaft (38.7), Siahkal (28.3), and Langrood (24.16). Allometric equations were established based on the highest correlation coefficient (r2) and the lowest standard error value (SE) between age as the independent variable and carbon as the dependent variable. Calculation of carbon sequestration in plantation stand stock and soil can provide insights into species function and their responses. Furthermore, comparing carbon sequestration in different sites can aid in the restoration of degraded lands and the conversion of such lands into high-yield plantations, which can be an effective measure in managing carbon sequestration using fast-growing species.
