“…In accordance with our model, the carbon content declined gradually with the rising altitude. Different results were found in Germany, where a higher carbon stock deposited in upper-layer humus at higher elevations and alpine sites where thick organic layers are common (Wiesmeier et al 2013;Grüneberg et al 2014). Nevertheless, these results are from alpine areas, where generally higher hummus accumulation occurs because of extreme climatic and site conditions.…”

“…It is estimated that approximately 30 to 50% of total carbon content in forests is located in soils (Dixon et al 1994;Paul et al 2002;Pan et al 2011;Wiesmeier et al 2013;Grüneberg et al 2014). The amount of accumulated carbon and its distribution in the soil profile is influenced by individual tree species (Augusto et al 2015;Andivia et al 2016).…”

Soil organic carbon (SOC) is a great component of the global carbon cycle and plays significant role in terms of climatic changes and agricultural land-use. An important management concern is the extent of SOC stocks sequestration when farmland is converted to forest stands. We have reviewed the literature about changes in SOC stock in relation to altitude and stand age and sought differences between former agricultural land and origin forest stands. Accumulation of SOC was monitored in 17 examples (41 samples) in 9 locations across the all Czech Republic with focus on the main tree species Norway spruce (Picea abies [L.] Karst.). Results showed a significant increase of SOC stock in an afforested farmland with increasing stand age. Another factor was the altitude. With increasing altitude, the carbon stock in our model gradually decreased. From the data analyzed comparing forest stand and former agricultural land, similar carbon sequestration was documented for both variants with higher SOC for forest stands. However, other conditions affecting SOC stock should be taken into consideration, especially silvicultural management, topography, disturbances, soil properties and cultivation. The general tendencies of SOC changes at the investigated sites are comparable to those in other studies across the Europe.

“…Though a lot of work has been done to study the positive effects of biodiversity on ecological function (Balvanera et al, 2006;Marquard et al, 2009), attention is rarely given to soil organic carbon (Vesterdal et al, 2013) and nitrogen stocks, which are closely related to global climate change. The limited research shows that the soil OC and N stocks in mixed stands do not necessarily exceed those of corresponding pure stands (Berger et al, 2002;Forrester et al, 2012;Wiesmeier et al, 2013;Wang et al, 2013;Cremer et al, 2016). Most previous studies did not consider the relative portion of the component species (Berger et al, 2002;Wang et al, 2013;Cremer et al, 2016), which may result in an underestimation of admixing effects.…”

Accumulation of soil organic C and N in planted forests fostered by tree species mixture

Abstract. With the increasing trend of converting monocultures into mixed forests, more and more studies have been carried out to investigate the admixing effects on tree growth and aboveground carbon storage. However, few studies have considered the impact of mixed forests on belowground carbon sequestration, particularly changes in soil carbon and nitrogen stocks as a forest grows. In this study, paired pure Pinus massoniana plantations, Cinnamomum camphora plantations and mixed Pinus massoniana-Cinnamomum camphora plantations at ages of 10, 24 and 45 years were selected to test whether the mixed plantations sequestrate more organic carbon (OC) and nitrogen (N) in soils and whether this admixing effect becomes more pronounced with stand ages. The results showed that tree species identification, composition and stand age significantly affected soil OC and N stocks. The soil OC and N stocks were the highest in mixed Pinus-Cinnamomum stands compared to those in counterpart monocultures with the same age in the whole soil profile or specific soil depth layers (0-10, 10-20 and 20-30 cm) for most cases, followed by Cinnamomum stands and Pinus stands with the lowest. These positive admixing effects were mostly nonadditive. Along the chronosequence, the soil OC stock peaked in the 24-year-old stand and was maintained as relatively stable thereafter. The admixing effects were also the highest at this stage. However, in the topsoil layer, the admixing effects increased with stand ages in terms of soil OC stocks. When comparing mixed Pinus-Cinnamomum plantations with corresponding monocultures within the same age, the soil N stock in mixed stands was 8.30, 11.17 and 31.45 % higher than the predicted mean value estimated from counterpart pure species plantations in 10-, 24-and 45-year-old stands, respectively. This suggests that these admixing effects were more pronounced along the chronosequence.

“…S2) might indirectly affect SOC by stimulating an increase in crop NPP (Tao and Zhang 2013;Tao et al 2014). Therefore, we can infer that climate effects are of minor importance in agricultural soils because agromanagement options counteract them to a certain extent (Wiesmeier et al 2013;Xu et al 2009); improvement in Horizontal line is the average value corresponding to land use in the bottom. Paddy is cropland where irrigated rice grown and upland is that where other crops are planted management practices should be a more important factor in the SOCC than the scenarios of climate change, which is consistent with the conclusions of Thomson et al (2006) and .…”

Aims Try to detect the spatiotemporal dynamics and the controlling factors of soil organic carbon (SOC) in the North China Plain (NCP) over the last 30 years: 1980s-2010s. Methods We investigated the SOC evolution by compiling data from 32 published papers during the last 30 years. Then we examined the spatial pattern and controlling factors by analysing a two-period sampling observations (1980s and 2010s) and multiple explanatory variables in four typical counties.
