“…However, SOC was more dependent on LULC type. LULC change was an important factor that weakened the coupling relationship between the changes in NPP and SOC density by altering the amount of litter input and litter quality as well as decomposition rate under given climate conditions (Poeplau and Don 2013;Shi et al 2013b). Slope degree and aspect did not significantly affect NPP or SOC density, which were consistent with some other studies (Wang et al 2002;Mueller and Pierce 2003).…”

Contex Soil carbon sequestration is an ecosystem process that can provide important ecosystem services such as climate regulation and mitigation of global warming. Spatiotemporal variation in the soil organic carbon (SOC) stock is the basic information needed for landscape management and determination of regional carbon budgets. Objectives The objective of this study was to evaluate the effect of ecological restoration on SOC stocks and determine the influences of multiple factors in the Yanhe watershed of the Loess Plateau. Methods We coupled the Yasso07 soil carbon model with remote sensing indices as model input. The model performance was evaluated by uncertainty and sensitivity analyses as well as validation against field measurement. Results The modeling captured the spatial pattern of SOC variability across the landscape generally well. Net primary productivity (NPP) was the foremost factor that affecting the spatiotemporal variation of SOC density. Converting cropland to grassland was the most efficient restoration type in soil carbon sequestration in the study period. Land use change influenced the spatial correlation between NPP and SOC density by altering both litter quantity and quality. The changes in land use area tended to have higher contributions to the changes in SOC stock than did the changes in SOC density for different land use types. Conclusions The overall effect of ecological restoration on soil carbon sequestration was dependent on the main vegetation restoration type and the time of recovery. Human-derived land use changes could have more substantial effects on soil carbon budgets compared to natural factors in a short period of time.

“…Soil C stocks generally increase on depleted ex-croplands, and remain unchanged or decrease on ex-grasslands and ex-pastures with the progressive disappearance of their abundant root litter [42][43][44][45][46]. For example, Guo et al [47] observed, in an afforested pasture with pines, that the loss of soil C was positively correlated with the mortality volume of fine roots.…”

“…However, the abundance and diversity of non-commercial species on NS sites suggests the presence of a multi-storey structure. Among non-commercial species, shrubs can play a key role, since their higher root:shoot ratio compared to trees [31] allows a higher C input to soil by root litter [45]. Finally, the higher frequency of Alnus rugosa on NS sites could have facilitated soil C sequestration by providing extra nitrogen input from bio-nitrogen fixation [48].…”

Abstract:The objective of this study was to compare organic carbon (C) accumulation in plantations (PL) and natural succession (NS) established on fallow lands along a 50-year chronosequence in the eastern mixed forest subzone of Quebec (Canada). Above-and below-ground woody biomass were estimated from vegetation measurement surveys, and litter and soil (0-50 cm depth) C from samplings. At the year of abandonment, total C content of both PL and NS sites averaged 100 ± 13 Mg C ha −1 . Over 50 years, total C content doubled on NS sites and tripled on PL sites (217.9 ± 28.7 vs. 285.7 ± 31.0 Mg ha −1 ) with respect to fallow land. On NS sites, the new C stocks accumulated entirely in the vegetation. On PL sites, C accumulated mostly in the vegetation and to a lesser extent in the litter, whereas it decreased by a third in the soil. As a result, the net C accumulation rate was 1.7 ± 0.7 Mg ha −1 yr −1 greater on PL sites than on NS sites over 50 years. By the 23rd year, PL sites became greater net C sinks than NS sites in the fallow lands of the study area, even with the loss of soil C.

“…These processes are influenced by a wide range of factors which need to be taken into account: (i) previous use and possible soil cultivation; (ii) type of woody plants; (iii) soil character of the site (texture, pH, sorption, etc. ); (v) afforestation method; (vi) topography and climate of the site (Guo, Gifford 2002;Shi et al 2013). Table 3 shows variant B where the selection criteria are slightly different from variant A (see Table 1).…”

Afforestation of agricultural lands may be a positive action in many cases. Especially, it is a beneficial feature for waterlogged soils, stony soils or for soils which are less fertile for any other reason and thus unsuitable for farming. Afforestation can be a very important action even in the agricultural landscape -afforested belts of agricultural land divide large farm blocks into smaller ones, or act as windbreakers and biological corridors. The value, quality and fertility of soil can be assessed in different ways. The study aims to determine the identification soil criteria of agricultural land which is suitable for afforestation. This evaluation process is based on Evaluated Soil Ecological Units (ESEU), in the Czech Republic known as BPEJ, database which is available for all agricultural land in the Czech Republic. The results are represented by a complete list of ESEU codes suitable for afforestation. The list of codes is supplemented by an explanation why such an ESEU code, representing a soil group with similar properties, is suitable to afforestation.
