“…Conversion of NF to RP and ArP depleted the SOC stock by 21% (64.0 Mg ha −1 ) and 59% (177.2 Mg ha −1 ) of ecosystem C, respectively. A similar trend of loss of the ecosystem C by 37% as compared with that under natural forest was estimated for Chinese fir plantations (Fan et al, ). The ecosystem C stock of PB being 11% less than that under NF suggests that traditional agroforestry management system accelerates biomass and soil C sequestration, which is similar to that for the NF.…”

“…The loss of vegetation C was as high as 83–85% when NF was converted into DF or ArP. Such a significant loss in vegetation C due to LUC into plantation/commercial crops has also been reported by Liao, Luo, Fang, and Li () and Fan et al (). The highest loss of vegetation C (93%) observed for IG is comparable to 95–98% loss of vegetation C stock in grasslands of Indonesia in comparison with that under natural forest (Palm, van Noordwijk, Woomer, et al, ).…”

“…The retrogressive change from NF to RP depletes SOC to 100 cm depth by 23%. In China, conversion of natural forest into Chinese fir ( Cunninghamia lanceolata ) and rubber plantations decreased SOC stock by 19–38% compared with that in soil under natural vegetation (Fan et al, ; Guillaume, Muhammad, & Kuzyakov, ). The SOC stock to 100 cm depth in IG (97.8 Mg ha −1 ) is in accord with that reported in other studies (Hendarson et al, ) and is ~27% lower than that of NF.…”

This study evaluated the ecosystem carbon (C) stock and sequestration potential for predominant land uses converted from forest in Northeast India to advance the scientific knowledge and minimize the anthropogenic C emissions from land use change (LUC). Field assessments were conducted on 6 predominant land uses including (a) natural forest (NF), (b) degraded forest (DF), (c) rubber (Hevea brasiliensis) plantation (RP), (d) Areca (Areca catechu) plantation (ArP), (e) pan (Piper betle) jhum (slash and mulching) agroforestry (PB), and (f) Imperata grassland (IG) of Northeast India to assess changes in ecosystem C stock with progressive and retrogressive LUC. Ecosystem C stock was the highest for NF (300.5 Mg ha À1) and the lowest under IG (110.4 Mg ha À1 ). The ecosystem C stock under PB and IG was 11% and 63%, respectively, lower than that under NF. In comparison with DF, the gain in ecosystem C was in the order PB (125%) > RP (99%) > ArP (4%). The ratio of soil organic carbon to ecosystem C stock was~50% for NF, PB, and RP and that shifted to~80% for ArP/DF/IG. The LUC and management of DF through PB and RP indicated the ecosystem C sequestration rate of 5 and 4 Mg ha À1 year À1, respectively. Similarly, the ecosystem C sequestration rate was 0.5 and 4 Mg ha À1 year À1 , respectively, when IG was converted into ArP and RP. Therefore, restoration of degraded lands (viz., DF and IG) through RP and PB enhanced ecosystem C sequestration rate and reduced CO 2 emissions from LUC.

Moso bamboo (Phyllostachys edulis (Carrière) J.Houz.) is famous for its fast growth and biomass accumulation, as well as high annual output for timber and bamboo shoots. Organic mulches are widely used to improve shoots' production in moso bamboo forests. However, continuous mulching management may cause bamboo forest degradation and affect sustainable development. The objective of this study was to identify the degradation mechanism and to provide a theoretical basis for recovery. A complete randomized block design with four treatments was conducted, including mulching for one year (M1), two years (M2), three years (M3) and no-mulching management (NM). Soil nutrient contents, enzyme activities and microbial biomass were determined. With the increase of mulching years, the soil pH value gradually reduced, causing soil acidification, but the content of soil organic matter was inclined to ascend. Soil total nitrogen (TN), total phosphorus (TP) and total potassium (TK) contents showed an increasing trend, and they were significantly higher in mulching stands than those in NM (p < 0.05). Contents of soil available nutrients (AN, AP and AK) increased, then decreased with the increase of mulching years and peaked in M1. With the increase of mulching years, the soil stoichiometry ratio (C/N, C/P and N/P) gradually increased. Soil invertase, urease and acid phosphatase activities presented a single-peak curve and reached the maximum within one year after mulching. Total microbial biomass and that of individual groups changed greatly after mulching. Soil microbial biomass increased first and then decreased, and it was the largest in M1. The fungi:bacteria ratio decreased in the first year and then began to rise, while the aerobic:anaerobic ratio showed the opposite trend. According to the overall results, M3 leads to soil acidification, imbalance of the nutrients' proportion, abnormal enzyme activity and change of soil microbial flora, and rotated mulching management (mulching one year and then recuperating one year) should be recommended in practice.

“…Soil carbon stocks are in fact a major indicator of atmospheric CO 2 exchanges, and soil can play a crucial role in the fight against global warming through its ability to store carbon [3][4][5]. In fact, several researchers have studied the capacity of soils to store carbon in various terrestrial environments (e.g., forests, prairies, and farmland) [6][7][8] and measured their variability based on land use [9][10][11]. Soil organic carbon can vary over space and time based on numerous soil conditions and soil-forming processes, including hydroclimatic and morphological factors [12][13][14].…”

Abstract:Measuring soil organic carbon (SOC) in riparian forest soils affected by floods is crucial for evaluating their concentration and distribution along hydrological gradients (longitudinal and transversal). Hydromorphological factors (e.g., sedimentation vs. erosion, size of floodplain, flood recurrence) may be the cause of major variations in the concentration of organic matter and SOC in soils and could have a direct impact on C levels in soil profiles. For this study, SOC concentrations were assessed in riparian soils collected along transects perpendicular to the riverbanks which cross through inundated and non-inundated zones. Other soil properties (e.g., acidity, nitrogen, texture, bulk density) that may affect the concentration of SOC were also considered. The main purpose of this study was to assess SOC concentrations in soils subjected to flooding with those outside the flood zones, and also measure various soil properties (in surface soils and at various depths ranging from 0 to 100 cm) for each selected area. Across the various areas, SOC shows marked differences in concentration and spatial distribution, with the lowest values found in mineral soils affected by successive floods (recurrence of 0-20 years). SOC at 0-20 cm in depth was significantly lower in active floodplains (Tukey HSD test), with average values of 2.29 ± 1.64% compared to non-inundated soils (3.83 ± 2.22%). The proportion of C stocks calculated in soils (inundated vs. non-inundated zones) was significantly different, with average values of 38.22 ± 10.40 and 79.75 ± 29.47 t·ha −1 , respectively. Flood frequency appears to be a key factor in understanding the low SOC concentrations in floodplain soils subjected to high flood recurrence (0-20 years).
