In a column experiment, we monitored rhizosphere effects on lime dissolution, CO2 effluxes, and the concentrations of dissolved inorganic carbon (DIC) and dissolved organic carbon (DOC) in leachate from an acidic Kandosol. The experiment consisted of four treatments viz: soil only (control), soil\u00a0+\u00a0lime, soil\u00a0+\u00a0wheat, and soil\u00a0+\u00a0lime\u00a0+\u00a0wheat. We measured CO2-C effluxes at 7, 43 and 98 days after planting (DAP) and leachate was collected at 56 and 101 DAP. The soil CO2-C efflux rate increased significantly with lime addition at 7 and 43 DAP compared to control. At 43 DAP, the largest increase in CO2-C effluxes was observed in the lime\u00a0+\u00a0wheat treatment. However, at 98 DAP similar CO2-C effluxes were observed from wheat and lime\u00a0+\u00a0wheat treatments, suggesting that most of the lime was dissolved in the lime\u00a0+\u00a0wheat treatment. Both DOC and DIC concentrations in the leachate increased significantly with lime and wheat only treatments (cf. control). In contrast to DOC, there was an increase in the DIC concentration in the soil leachate from lime\u00a0+\u00a0wheat treatment columns at 101 DAP (significant wheat\u00a0\u00d7\u00a0lime interaction), thus, accentuating the pronounced role of wheat roots. We conclude that plant mediated dissolution of lime increased the concentration of DIC in the soil leachate, while both liming and presence of plants enhanced DOC leaching.", "keywords": ["2.

We analyzed the impact on SOC of four N fertilization rates (0\uffe2\uff80\uff93270 kg N ha\uffe2\uff88\uff921) and four cropping systems: continuous corn (CC) (Zea mays L.); corn\uffe2\uff80\uff93soybean [Glycine max (L.)

Cropping systems that contained alfalfa had the highest SOC stocks, whereas the CS system generally had the lowest SOC stocks. Concentrations of SOC increased significantly between 1990 and 2002 in only two of the nine systems for which historical data were available, the fertilized CC and COAA systems at one site. Soil quality indices such as particulate organic carbon (POC) were influenced by cropping system, with CS &lt; CC &lt; CCOA. In the native prairie, SOC, POC, and resistant C concentrations were 2.8, 2.6, and 3.9 times, respectively, the highest values in cropped soil, indicating that cultivated soils had not recovered to precultivation conditions. Although corn yields increased with N additions, N fertilization increased SOC stocks only in the CC system at one site.

Widespread shrub encroachment in global drylands may increase plant  biomass and change soil organic carbon stocks of grassland ecosystems.  However, the response of soil inorganic carbon (SIC), which is a major  component of dryland carbon pools, to this vegetation shift remains  unknown. 2. We conducted a systematic field survey in 75 pairs of  shrub-encroached grassland and control plots at 25 sites in the grasslands  of the Inner Mongolia Plateau to evaluate how shrub encroachment affects  SIC density (SICD) in these ecosystems. 3. We found that shrub  encroachment significantly reduced SICD in the upper 100 cm (3.85 vs. 4.74  kg C m-2, P &lt; 0.05), especially in the subsurface soil (20-50 cm  layer). The magnitude of SICD changes was related to the change in soil  pH, shrub patch size, and initial SICD, reflecting that the reduction in  SICD might be attributed to the shrub encroachment-related soil  acidification. Our results also revealed that the lost SIC was mainly  released into the atmosphere rather than redistributed into deeper soil  layers. 4. Synthesis. We provide the first evidence for the soil  acidification-induced SIC loss caused by shrub encroachment.

However, to date, few studies have addressed these processes. Here, we use meta-analysis and nationwide-survey datasets to investigate changes in soil inorganic carbon (SIC) stocks in China. We observe an overall decrease in SIC stocks in topsoil (0\uffe2\uff80\uff9330\uffc2\uffa0cm) (11.33\uffc2\uffa0g C m\uffe2\uff80\uff932 yr\uffe2\uff80\uff931) from the 1980s to the 2010s. Total SIC stocks have decreased by \uffe2\uff88\uffbc8.99\uffc2\uffa0\uffc2\uffb1\uffc2\uffa02.24% (1.37\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.37\uffc2\uffa0Pg C). The average SIC losses across China (0.046 Pg C yr\uffe2\uff80\uff931) and in cropland (0.016 Pg C yr\uffe2\uff80\uff931) account for \uffe2\uff88\uffbc17.6%\uffe2\uff80\uff9324.0% of the terrestrial C sink and 57.1% of the soil organic carbon sink in cropland, respectively. Nitrogen deposition and climate change have profound influences on SIC cycling. We estimate that \uffe2\uff88\uffbc19.12%\uffe2\uff80\uff9319.47% of SIC stocks will be further lost by 2100. The consumption of SIC may offset a large portion of global efforts aimed at ecosystem carbon sequestration, which emphasizes the importance of achieving a better understanding of the indirect coupling mechanisms of nitrogen and carbon cycling and of effective countermeasures to minimize SIC loss.</p", "keywords": ["Carbon sequestration", "Cartography", "China", "Mechanics and Transport in Unsaturated Soils", "Carbonate", "Nitrogen", "Soil Science", "Organic chemistry", "Carbon Dynamics in Peatland Ecosystems", "soil inorganic carbon stocks", "Soil pH", "Environmental science", "Carbon sink", "Agricultural and Biological Sciences", "carbonate", "Engineering", "Soil water", "Soil Carbon Sequestration", "Biology", "global change", "Ecosystem", "Soil acidification", "Civil and Structural Engineering", "Soil science", "2.
