“…The majority of fine root C was located in the upper 40 cm soil depth (data not shown) due to abundant water and nutrients, which is consistent with recent findings in other tree species [40,41]. Furthermore, litter C stock increased with stand age.…”

“…By contrast, Nizami et al [21] predicted rubber plantation to be a smaller C sink (186.7 Mg ha −1 ) in a 40-year rotation using the CO 2 FIX Model. Another important finding was that SOC stock was relatively stable over age sequence, whereas its contribution to TEC decreased rapidly with stand age (Figure 3), similar to the results from Pinus strobus [36] and Cyclobalanopsis glauca [41] plantations. This trend did not occur in some other plantations due to the differences in the rates of biomass and soil C accumulation among tree species during stand development [40,44].…”

Abstract:Transition from forest to rubber (Hevea brasiliensis Muell. Arg.) plantation has occurred in tropical China for decades. Rubber has been planted on 1 million ha to provide raw materials to the rubber industry. The role of various-aged rubber plantations in carbon (C) sequestration remains unclear. The biomass C accumulation including latex C and C distribution in soil of five different-aged stands (7,13,19,25 and 47 years old) were examined. The total biomass C stock (TBC) and total net primary productivity (NPP total ), whether with or without latex C, had a close quadratic relationship with stand age. Regardless of stand age, around 68% of the C was stored in aboveground biomass, and NPP latex contributed to approximately 18% of C sequestration. Soil organic carbon stock in the 100-cm depth remained relatively stable, but it lost about 16.8 Mg ha −1 with stand age. The total ecosystem C stock (TEC) across stands averaged 159.6, 174.4, 229.6, 238.1 and 291.9 Mg ha −1 , respectively, of which more than 45% was stored in the soil. However, biomass would become the major C sink rather than soil over a maximal rubber life expectancy. Regression analysis showed that TEC for rubber plantation at 22 years is comparable to a baseline of 230.4 Mg ha −1 for tropical forest in China, and would reach the maximum value at around 54 years. Therefore, rubber plantation can be considered as alternative land use without affecting net forest ecosystem C storage. In addition to the potential C gains, a full set of ecosystem and economic properties have to be quantified in order to assess the trade-offs associated with forest-to-rubber transition.

“…This is very close to the study in an age-sequence of Cyclobalanopsis glauca plantations in southwest China [51] in which soil C storage at a depth of 0 to 100 cm was 70.38, 90.84, 84.39, 107.99 Mg·ha −1 and ecosystem C storage was 110.83, 169.09, 174.80, and 222.68 Mg·ha −1 in 8-, 20-, 40-, 70-year old Cyclobalanopsis glauca stands, respectively. The average ecosystem C storage was 155.17 Mg·ha −1 , was bigger than 144.86 Mg·ha −1 determined by Cui et al [44] in Quercus spp.…”

Large-scale Quercus variabilis natural secondary forests are protected under the Natural Forest Protection (NFP) program in China to improve the ecological environment. However, information about nutrient characteristics and carbon (C) storage is still lacking. Plant biomass and C, nitrogen (N) and phosphorus (P) stoichiometry of tree tissues, shrubs, herbs, litter, and soil were determined in young, middle-aged, near-mature and mature Quercus variabilis secondary forests in the Qinling Mountains, China. Tree leaf N and P concentrations indicated that the N-restricted situation worsened with forest age. The per hectare biomass of trees in decreasing order was near-mature, mature, middle-aged, then young stands. The majority of the biomass was in the stems (44.88-48.15%), followed by roots (24.54-28.68%), and branches (10.15-14.16%), and leaves made up the lowest proportion (2.86-3.55%) of trees. C storage at plant layer increased significantly with age, reaching maximum values in near-mature stand (100.4 Mg·ha −1 ) and then decreasing in mature stands. Soil C storage at a depth of 0 to 100 cm was 82.8, 96.8, 85.8, 104.2 Mg·ha −1 , and C storage of forest ecosystem was 122.8, 163.0, 184.9, 178.3 Mg·ha −1 in young, middle-aged, near-mature, mature stands, respectively. There were significant correlations between biomass and C, N, P stoichiometry in different layers, especially in young stands.

“…Three 40 m × 50 m plots were established for all three stands in a regular slope-depression continuum in October 2014. The plots were established following the standard of the Center for Tropical Forest Science [18,19], and were divided into ten 10 m × 10 m quadrats. Tree density, tree height (H), and tree diameter at breast height (DBH) were recorded in each plot.…”
