“…This was due to different land use (vegetation) species having different N requirements, exploiting N with varying efficiency and storing or converting N at different rates (Aert and Chapin, 2000;Chen and Li, 2003). The distribution of soil N has a close relationship with root distribution (Berger et al, 2002). Many studies have …”

Understanding the effects of land use change on soil properties is important for soil quality improvement and sustainable land use. In this study, six land use types including wasteland (WLD), cropland (CLD), abandoned land (ABD), artificial grassland (AGD), shrubland (SLD) and woodland (WOD) were selected to analyse the effects of land use types on soil nutrient in the Anjiapo catchment in the western part of the Loess Plateau in China. Significant differences were found in soil organic matter (SOM), total nitrogen (TN) and nitrate nitrogen (NON) (P < 0.01) between the six land use types. Our study also showed that land use types have different effects on soil nutrient storage, and vegetation restoration may improve soil nutrients and soil quality. While crop plantation can significantly decrease soil fertility, the trend can be reversed by cropland abandonment and afforestation. It is recommended that more C input, alternative cultivation practices, vegetation restoration and education and techniques training of local farmers could be used to improve soil conditions and to advance the sustainable land use and local development in the loess hilly area in the Loess Plateau of China.

“…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.…”

For example, admixing effects could also exist because of the small portion of higher-production species, which leads to low expected production even if the production of a twospecies mixed stand is between that of two corresponding pure stands.…”

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.

“…Based on the regression between log organic carbon and δ 13 C, we found that SOC turnover was slower in the mature forest than in the disturbed and rehabilitated forests (Table 3), which was partially attributed to thicker soil and higher silt and clay content (Table 1). Plant roots were prone to extend downwards to absorb nutrients in the deeper soil layers, which can increase root biomass and decrease the decomposition of root residues (Jobbágy and Jackson 2000;Berger et al 2002). Soil clay and silt had strong ability to conserve soil organic matter, thus SOC associated with fine soil particles was difficult to be decomposed by soil microorganism (Garten et al 1999;Carter et al 2003).…”

Chronic atmospheric nitrogen deposition affects the cycling of carbon (C) and nitrogen (N) in forest ecosystems, and thereby alters the stable C isotopic abundance of plant and soil. Three successional stages, disturbed, rehabilitated and mature forests were studied for their responses to different nitrogen input levels. N-addition manipulative experiments were conducted at low, medium and high N levels. To study the responses of C cycling to N addition, the C concentration and 13 C natural abundances for leaf, litter and soil were measured. Labile organic carbon fractions in mineral soils were measured to quantify the dynamics of soil organic C (SOC). Results showed that three-year continuous N addition did not significantly increase foliar C and N concentration, but decreased C/N ratio and enriched 13 C in N-rich forests. In addition, N addition significantly decreased microbial biomass C, and increased water soluble organic C in surface soils of N-rich forests. This study suggests that N addition enhances the water consumption per unit C assimilation of dominant plant species, restricts SOC turnover in N-poor forests at early and medium successional stages (thus favored SOC sequestration), and vice versa for N-rich mature forests.
