Carbon accumulation in agricultural soils after afforestation: a meta-analysis.
TLDR
In this paper, the authors provide a review of the influence of afforestation on soil organic carbon (SOC) stocks based on a meta-analysis of 33 recent publications (totaling 120 sites and 189 observations).Abstract:
Deforestation usually results in significant losses of soil organic carbon (SOC). The rate and factors determining the recovery of this C pool with afforestation are still poorly understood. This paper provides a review of the influence of afforestation on SOC stocks based on a meta-analysis of 33 recent publications (totaling 120 sites and 189 observations), with the aim of determining the factors responsible for the restoration of SOC following afforestation. Based on a mixed linear model, the meta-analysis indicates that the main factors that contribute to restoring SOC stocks after afforestation are: previous land use, tree species planted, soil clay content, preplanting disturbance and, to a lesser extent, climatic zone. Specifically, this meta-analysis (1) indicates that the positive impact of afforestation on SOC stocks is more pronounced in cropland soils than in pastures or natural grasslands; (2) suggests that broadleaf tree species have a greater capacity to accumulate SOC than coniferous species; (3) underscores that afforestation using pine species does not result in a net loss of the whole soil-profile carbon stocks compared with initial values (agricultural soil) when the surface organic layer is included in the accounting; (4) demonstrates that clay-rich soils (> 33%) have a greater capacity to accumulate SOC than soils with a lower clay content (< 33%); (5) indicates that minimizing preplanting disturbances may increase the rate at which SOC stocks are replenished; and (6) suggests that afforestation carried out in the boreal climate zone results in small SOC losses compared with other climate zones, probably because trees grow more slowly under these conditions, although this does not rule out gains over time after the conversion. This study also highlights the importance of the methodological approach used when developing the sampling design, especially the inclusion of the organic layer in the accounting.read more

Land-use conversion and changing soil carbon stocks in China's 'Grain-for-Green' Program: a synthesis.
TL;DR: Soil C sequestration significantly increased with restoration age over the long-term, and therefore, the large scale of land-use change under the 'Grain-for-Green' Program will significantly increase China's C stocks.

Global patterns of the dynamics of soil carbon and nitrogen stocks following afforestation: a meta-analysis
Dejun Li,Shuli Niu,Yiqi Luo +2 more
TL;DR: It is indicated that soil C and N stocks both increase with time after afforestation, and that C sequestration through Afforestation depends on prior land use, climate and the tree species planted.

Sensitivity of soil organic carbon stocks and fractions to different land-use changes across Europe
Christopher Poeplau,Axel Don +1 more
TL;DR: In this article, the authors investigated qualitative and quantitative effects of land use changes on soil organic carbon (SOC) and found that land use change can influence the balance of soil organic CO 2 emissions or sequestration.

The vertical distribution of soil organic carbon and its relation to climate and vegetation
TL;DR: In this paper, the authors examined the association of soil organic carbon (SOC) content with climate and soil texture at different soil depths, and tested the hypothesis that vegetation type, through patterns of allocation, is a dominant control on the vertical distribution of SOC.

Stabilization mechanisms of soil organic matter: Implications for C-saturation of soils
TL;DR: The relationship between soil structure and the ability of soil to stabilize soil organic matter (SOM) is a key element in soil C dynamics that has either been overlooked or treated in a cursory fashion when developing SOM models as discussed by the authors.

L. B. Guo,R. M. Gifford +1 more
TL;DR: In this article, the influence of land use changes on soil carbon stocks was reviewed and a meta-analysis of these data from 74 publications was conducted, which indicated that soil C stocks decline after land use change from pasture to plantation (−10%), native forest to plantations (−13), native forests to crop (−42), and pasture to crop (+59%), while the reverse process usually increased soil carbon and vice versa.
