Abstract. Afforested drained peatlands have significant implications for greenhouse gas (GHG) budgets, with contrasting views on their effects climate. This study utilized the dynamic ecosystem model ForSAFE-Peat to simulate biogeochemical dynamics over two full forest rotations (1951–2088) in a nutrient-rich peatland afforested Norway spruce (Picea abies) southwest Sweden. Model simulations aligned well observed groundwater levels (R² = 0.71) and soil temperatures ≥ 0.78), captured seasonal annual net production patterns, although daily variability was not always represented. outputs were analysed under different system boundaries (soil, ecosystem, plus fate of harvested wood products named ecosystem+HWP) assess carbon exchanges using balance (NCB) integrated storage (ICS) metrics. Results indicated negative NCB ICS across all boundaries, except positive calculated by end simulation at ecosystem+HWP level. The exhibited persistent losses primarily driven peat decomposition. At level, reduced as growth partially offset until harvesting. (1015 gC m-2soil) level due slow decay products, but (-7.0×105 gC yr initial losses. highlights importance boundary selection temporal assessing peatlands.

Within this study, we evaluated the fine root (trees and understory vegetation combined) morphological traits, production (FRP), carbon (C) input with litter in forest stands (dominated by either coniferous or deciduous trees) clearcut areas (previously dominated nutrient-rich organic soils. The study was conducted 26 sites hemiboreal land Latvia summarizes results obtained a two-year (2020–2022) using ingrowth method. Traits of roots varied significantly depending on development stage (stand area), dominant tree species type (coniferous deciduous), soil drainage status (drained naturally wet). According to second year, mean FRP among groups from 0.58 ± 0.13 1.38 0.28 t ha−1 yr−1, while C ranged 0.06 0.68 0.14 yr−1. More than half (59 4%) total occurred upper 0–20 cm layer. tended correlate positively C/N ratio negatively pH nutrient concentration. Incubating cores for at least two years is strongly recommended accurately estimate annual input. This helps avoid potential underestimation that may occur when only one incubation year (12 months after core installation). provided new insights into dynamics traits will help improve accuracy flow estimation forests soils Latvia.
