“…The consequences of revegetation on the soil organic carbon stocks SOC stocks were significantly greater in natural grassland and C. korshinskii shrublands than those in cropland. This finding is consistent with previous studies (Mensan et al 2003;Jia et al 2010;An et al 2010;Lenka et al 2012) that showed that SOC increased with the development of shrubs and grass. The lower SOC stocks in cropland have been attributed to lower carbon inputs and higher carbon mineralization (Skjemstad et al 2008;Nyamadzawo et al 2009).…”

“…Revegetation may lead to accumulation of SOC by increasing carbon derived from the new vegetation type and decreasing carbon loss by decomposition and erosion (Laganière et al, 2010). Numerous studies have been conducted investigating the effects of revegetation on soil carbon sequestration (Mensan et al 2003;Ashagrie et al 2005;Yue et al 2007;Han et al 2008;Haile et al 2008;An et al 2010;Jia et al 2010;Lenka et al 2012;Wei et al 2012;Feng et al 2013). However, the accumulation of soil carbon fractions induced by revegetation is not well understood.…”

Estimating the distribution of soil organic carbon (SOC) is essential for improving SOC sequestration. Our objectives were (1) to quantify the dependency of SOC stocks on vegetation type; (2) to identify in which aggregate sizes and chemical forms the SOC was stored; and (3) to determine which vegetation type was the most effective at sequestering SOC.

The studied vegetation types were shrubland CK16 (16-year-old Caragana korshinskii Kom.), shrubland CK26 (26-year-old C. korshinskii Kom.), shrubland AS (Armeniaca sibirica Lam.), natural grassland and artificial pasture. We investigated SOC stocks and measured soil carbon, in <0.25, 0.25–1, 1–2, 2–5 and 5–8 mm sized aggregates, and carbon fractions [humus (HS-C), humic acid (HA-C), fulvic acid (FA-C)] from CK shrublands, natural grassland and cropland.

The SOC stocks were the greatest for CK shrublands and natural grassland. Compared with cropland, shrubland CK caused increases in >2 mm sized aggregate C stocks. The 1–2, 2–5, 5–8 mm size aggregate C stocks were the highest in the natural grassland. HS-C was 1.4, 3.1, and 4.1 Mg ha−1 greater in shrubland CK16, shrubland CK26, and natural grassland, respectively, than in cropland.

Conversion to C. korshinskii shrublands and protection of natural grassland should be promoted to improve the contribution of vegetation to SOC sequestration

“…The significant increase of MBC in M1 and M2 compared to CK led to a higher ratio of MBC/SOC in M1 and M2 than in CK. And the MBC/SOC ratio generally ranges from 0.01 to 0.04 in this region [4,11]. In the present study, it ranged from 0.03 to 0.09 depending on how long the mulch material stayed in place, which improved with the increase of mulching time.…”

“…Furthermore, advanced techniques and methods are widely used to determine above-ground biomass [9,10]. For example, height (H), branch diameters (D), crown volume (C v ), and crown cover (C) may be employed in biomass estimation models as the independent variables [11][12][13][14][15]. As for trees, stem-related variables, specifically height (H) and diameter (D), have proven to accurately predict individual biomass [4,10,14].…”

The quantification of above-ground biomass is based on the calculation of carbon storage, which is important for the balance of carbon cycling. However, the allometric models of shrubs for calculating the above-ground biomass of shrubs in the Loess Plateau are scarce. In order to solve this issue, this study analyzed some highly correlated variables, including height (H), branch diameters (D), canopy volume (Cv), canopy area (Ca), and then built a regression model to predict the above-ground biomass in two common shrubs (Caragana korshinskii and Sophora viciifolia) in the Loess Plateau, China. The results show that the above-ground biomass of these two shrubs can be accurately predicted by H and D, and then we can use allometric model (y = axb) to calculate shrub above-ground biomass (including leaf biomass and branch biomass). Furthermore, the correlation between leaf biomass and branch biomass in Caragana korshinskii and Sophora viciifolia indicates that the components of above-ground biomass are closely related to each other. In addition, there is a strong linear relationship (p < 0.01) between the observed and estimated biomass values, which confirms the data accuracy of the above-ground biomass estimation models. In summary, these two biomass estimation models provide an accurate way to estimate the quantification of carbon for shrubs in the Loess Plateau.
