“…plantations markedly reduced the SOC content as compared with abandoned lands, but the SOC content did not vary with plum plantation age; however, the cumulative and potential SOC mineralization rates were different among plum plantation ages, and both increased with increasing soil calcium concentration; thus, more attention should be paid in the future to the critical role of calcium in SOC mineralization in the studied subtropical area [17]. In contrast, the study conducted by Zhao et al in a larch (Larix principis-rupprechtii Mayr) forest showed that the contents of SOC, total N and total K were all increased with increasing stand age, and clear-cutting reduced SOC, total N, and total K contents [18]. The effect of the conversion of natural evergreen broadleaved forests to an assisted natural regeneration and Chinese fir (Cunninghamia lanceolata (Lamb.)…”

Forests cover around 30% of the global land area and forest ecosystems can store over 70% of total soil organic carbon (SOC) of all terrestrial ecosystems, but SOC stocks and greenhouse gas (GHG) emissions may be affected by both natural and anthropogenic disturbances. Even though the changes in forest soil C pool can have a significant effect on climate change, there are some contradictory results regarding the role of forest disturbance on SOC sequestration, GHG emissions, and the mitigation of global changes. Therefore, there is a need to better understand the impact of different disturbance regimes on forest soil C storage and GHG emissions. A Special Issue was therefore organized for discussing the responses of soil C storage and GHG emissions to various types of disturbances in forest ecosystems and a total of 15 studies were accepted for this special issue to assess these responses. This Special Issue includes the effects of storms and beetle outbreaks, Karstification, rock desertification, warming, nitrogen addition, land-use change, field tillage, and biochar application on soil C dynamics and/or GHG emissions.Disturbances from natural (e.g., insect outbreaks, geologic processes and wildfires) and anthropogenic (e.g., logging, applying soil amendments and land use change) are important drivers of changes of ecological processes in forest ecosystems, and the impact of disturbances on ecosystem processes may vary with the type and level of disturbances [1-3]. These disturbances are expected to markedly affect the amount, form and stability of soil organic carbon (SOC) and the emission of three major trace greenhouse gases (GHGs) (CO 2 , CH 4 and N 2 O) from forest ecosystems [4,5]. More than 70% of total SOC of all terrestrial ecosystems can be found in forest ecosystems [6] and thus, a minor change in the size of the forest SOC pool can exert a large impact on climate change on a global scale. The assessment of the variability in forest SOC storage and GHG emissions is thus a critical consideration for evaluating regional and global climate change [7]. It is vitally important to improve the understanding of the impact of different disturbance regimes on forest SOC storage and GHG emissions for guiding future research, forest management practices, and policy development. We therefore organized a Special Issue to bring together researchers working on different aspects of forest ecology to share their findings on disturbance effects on SOC storage and GHG emissions in forest ecosystems. We are pleased that we received a strong response from the scientific community to this call for the Special Issue and a total of 15 papers have ultimately been accepted for inclusion in this Special Issue.Three papers in this Special Issue address the effect of natural disturbances on SOC content and GHG emissions. Storms and beetle outbreaks are two major forms of disturbance in European forests,

“…Huong et al (2015) identified an opportunity to increase and sustain production of tree plantations over at least three rotations through better management practices. For example, in Eucalyptus and Prince Ruprecht's larch, Zhang et al (2015) and Zhao et al (2019) observed a long‐term improvement in soil quality with reduced soil disturbance during logging, keeping understory coverage and litter retention. These general recommendations need to be tested under local agronomic constraints (e.g., pest pressures) and socio‐economic bottlenecks (e.g., shortfall in timber sales) that have to be included in any changes made in smallholder plantations.…”

Rubber, rubber and rubber: How 75 years of successive rubber plantation rotations affect topsoil quality?

et al. 2022

Rubber tree plantations (Hevea brasiliensis) cover large areas in the tropics. In historical producing regions like South Thailand, rubber has been planted by smallholders for three successive rotations lasting a total of 75 years. Despite possible consequences on topsoil, the long‐term impacts of repeated rubber plantations on soil quality remain unknown. This study aims to better understand how various factors linked to long‐term rubber land use and land use change affect topsoil physico‐chemical properties and soil organic carbon (SOC) thermal stability. We focus on the effects of three factors: i. deforestation (change from forest to first rubber plantation); ii. the age of the rubber stand (immature vs. mature); and iii. long‐term rubber cultivation (first, second or third successive rotation) over a chronosequence in farmers plots. Our results show that soil was deeply degraded after deforestation to a rubber plantation. Long‐term rubber cultivation is also detrimental for the soil and has a more negative impact on soil physico‐chemical properties and carbon dynamics, than the age of the rubber stand (e.g., on average, decrease of 50% of SOC content between forest and third rotation). At the third rotation, after 50 years of rubber cultivation, the quality of the 0–10 cm soil layer was very low, with an increase in SOC thermal stability. At this stage, logging practices upset the sustainability of the system. These impacts could be limited by less destructive practices during planting.

The bare lands formed after volcanic eruptions provide an excellent opportunity to study the interactions between vegetation succession and soil formation. To explore the changes in soil physicochemical properties in the vegetation succession processes and the relationship between them, soil physicochemical properties of different volcanic ash accumulation on Miyake-jima Island were studied at different vegetation succession stages. The results showed that soil bulk density gradually decreased and that soil porosity, soil water content (SWC), pH, cation exchange capacity (CEC), soil total organic carbon (TOC), and total nitrogen (TN) increased significantly with vegetation succession. The physicochemical properties changes in the soil surface horizon were most obvious, and the deep soil accumulated a large amount of relatively stable soil carbon and nitrogen. The forest land formed a thicker organic matter horizon, accumulating more carbon and nitrogen than grassland, and the soil quality index (SQI) was higher than that of grassland and shrubland. In conclusion, our research indicates the significant change in soil physicochemical properties and the improvement in soil quality in the vegetation succession processes, emphasizing a significant relationship between vegetation succession and soil development in bare land.
