“…Researchers have investigated the effects of afforestation on soil carbon and nitrogen storage, and especially on SOC storage, because of the roles of this storage in determining soil quality and in the carbon cycle of arid and semiarid areas [34][35][36][37]. In the present study, we quantified the effects of the conversion of sand dunes to shrub plantations in a semiarid region of northern China.…”

“…We found accumulation of 1004, 346, and 360 kg·C·ha −1 ·yr −1 for SOC to a depth of 100 cm, respectively, 9, 15, and 31 years after planting, versus 96, 33, and 47 kg·N·ha −1 ·yr −1 for TN. In China's semiarid Shanxi Province, the conversion of degraded wastelands to Pinus tabulaeformis plantations increased SOC to a depth of 100 cm by 383 kg·C·ha −1 ·yr −1 , but decreased the corresponding TN by 6.5 kg·N·ha −1 ·yr −1 24 years after planting, versus decreases of 1098 kg·C·ha −1 ·yr −1 for SOC and 119 kg·N·ha −1 ·yr −1 for TN 8 years after planting [36]. In semiarid Patagonia, the SOC in afforested systems 15 years after planting did not differ from that in adjacent degraded steppes [5].…”

Caragana microphylla, a native perennial leguminous shrub, is widely used for desertification control in China's Horqin Sandy Land. We investigated the effects of afforestation using C. microphylla in areas with fixed and active dunes on soil carbon (C) and nitrogen (N) storage in the soil total and light-fraction (LF) organic matter. Compared to the values in the control areas, soil organic carbon (SOC) storage to a depth of 100 cm increased by 88%, 74%, and 145% at 9, 15, and 31 years after shrub planting, respectively; the corresponding values were 68%, 61%, and 195% for total nitrogen (TN) storage, 109%, 199%, and 202% for LF organic carbon storage, and 203%, 337%, and 342% for LF nitrogen storage. The soil light-fraction (LF) organic matter contributed significantly to total SOC and TN storage, despite the low proportion of total soil mass accounted for by the LF dry matter. Thus, afforestation using C. microphylla was an effective way to sequester C and to restore degraded soils, but the process was slow; it would take more than 100 years to fully restore SOC storage in active dunes through afforestation with C. microphylla in the Horqin Sandy Land.

“…Soil bulk density is the major discriminating factor in soil properties in relation to land use and management (Tisdall & Oades 1982, Zenga et al 2014, Matano et al 2015. Soil bulk density integrates effects of management and OM decline; these factors in conjunction result in smaller pore volumes and thus higher bulk densities.…”

Land-use changes and afforestation activities are widely recognized as possible measures for mitigating climate change through carbon sequestration. The present study was conducted to evaluate the effect of afforestation on (i) soil physical and chemical properties and soil carbon stocks in four mountain ecosystems and (ii) whole ecosystem carbon storage. The four experimental sites, situated in the Western Rhodope Mountains (Bulgaria) were characterized by typical forest-related land-use conversions. The four sites were a Douglas fir (Pseudotsuga menziesii [Mirb.] Franco) plantation (Rd1) established on former cropland, a mixed black pine (Pinus nigra Arn.) with Scots pine (Pinus sylvestris L.) plantation (Rd2) established on former cropland, a cropland (RdA1) and an abandoned land with uncontrolled extensive grazing (RdA2) historically used as cropland. Soil parameters, i.e., sand content, pH, organic C and N contents, C/N ratio and soil organic carbon (SOC) stocks, were significantly affected by land use and land-use history. Conversion from cropland into forestland significantly reduced soil bulk density and coarse fragments at 0-10 cm depth. Compared with adjacent cropland and abandoned land, soils in coniferous plantations were acidified in their upper layers. Sites Rd2 and RdA2 contained the least SOC owing to the previous long-term arable cultivation (>100 years). Analysis of the ecosystem C stock distribution revealed that most of C in forests was stored in the aboveground tree biomass. Our study confirmed that afforestation of cropland turned the soil into a C sink for the selected mountain region, but showed conflicting results when afforestation occurred on abandoned cropland.

“…As the repository for approximately 60% of the global terrestrial C pool, soil organic matter (SOM) is sensitive to agricultural management such as tillage (Dikgwatlhe et al, 2014;Urioste et al, 2006), fertilization (Su et al, 2006;Yang et al, 2007), land use change (Gami et al, 2009;Post and Kwon, 2000;Wei et al, 2014aWei et al, , 2014b, grazing (Pringle et al, 2014;Silveira et al, 2013) and afforestation and deforestation Zeng et al, 2014). Contradictory results on the impacts of afforestation and land management change on soil C and TN sequestration have been reported Parras-Alcántara et al, 2014;Perez-Quezada et al, 2011;Zeng et al, 2014) due to the dependence on tree types, stand ages, soil properties and depth and previous land uses (Côté et al, 2000;Wei et al, 2012;Zeng et al, 2014). Changes in pedogenic and hydrological processes caused by natural factors and human activities both affect C and N cycles.…”
