“…However, certain factors only impact the spatial distribution of SOC at specific scales (Wiesmeier et al, 2019). Specifically, stand age can significantly impact the edaphic properties, microbial activity, and plant carbon input by influencing water and heat fluxes as well as light conditions in the forest (Lucas‐Borja et al, 2016; Song et al, 2022; Trogisch et al, 2016; Zhang et al, 2019). This plays a crucial role in the regulation of SOC storage.…”

Understanding the dynamic relationships between soil organic carbon (SOC) and stand age are essential to quantify and predict the terrestrial carbon sequestration potential. However, the spatial patterns in the response of rubber plantation SOC to stand age and their driving factors remain unclear. Based on SOC and its components measurement at different soil depths (0–40 cm) in rubber plantations under five different age classes (0–5, 5–10, 10–20, 20–30, and >30 years) in three major rubber cultivation regions in China, distribution pattern and controlling factors of SOC were investigated. We found that SOC and its components showed significant spatial variability vertically with soil depth and laterally across sampling sites. SOC contents in three major rubber cultivation regions range from 4.48 to 20.13 g kg−1 at a depth of 0–40 cm. Among the sampling sites, Jinghong had the highest SOC content at a depth of 0–10 cm (20.13 g kg−1). On a large‐scale, the relationship between SOC and stand age in rubber plantations did not show a consistent pattern among different sampling sites. Additionally, annual rainfall, soil moisture content, and soil pH had a stronger impact on SOC in rubber plantations compared to stand age. The results indicated that the spatial variability of SOC in rubber plantations with stand age could be influenced by specific soil properties and climate‐related variables at each sampling site. This study emphasized the significance of conducting multi‐site, multi‐scale studies to enhance our understanding of SOC dynamics and its influencing factors, and help to more accurately predict the dynamic changes of soil carbon storage in rubber plantations.

“…Soil microbial communities also vary among forests of different ages and layers [21,22]. The total species number is signi cantly lower in older stands, and the composition of microbial communities is shaped by age [23][24][25]. Continuous cultivation of single-age monocultures might be negative feedback on the soil microbial community [26].…”

Understanding changes in the distribution patterns and diversity of soil microbial communities from the perspectives of age-related changes, seasonal variations, and the interaction between the two factors can facilitate the management of plantations. In Chinese fir plantations, we collected soils from different depths in overmature forests (OMF), mature forests (MAF), near-mature forests (NMF), middle-aged forests (MIF), and young forests (YOF) in summer, autumn, and winter in China's subtropical regions. As the forests developed, the fungal community recovered high diversity in MAF and OMF while bacterial indicators continued to decline. Bacterial communities were more diverse in summer and fungal communities were more diverse in winter. Differences between seasons were mainly reflected in average and maximum temperature indicators. Bacteria clustered by season, while fungi clustered by developmental stage, showed differences in distribution and structure at different taxonomic levels. The fungal community is a more important indicator of soil fertility maintenance, increasing with the increase of forest age, which suggested that extending tree cultivation time could improve the soil fertility of plantations. In different seasons and different ages, we found some species worthy of attention, including Actinobacteria with high abundance in summer and Bacteroidetes in autumn in overmature forests, and Firmicutes in summer in young forests. In autumn, species like Arcopilus and Tolypocladium in near-mature and over-mature forests also have the significance of further research, which may be key species for soil fertility restoration.
