Ecosystem Carbon Pools

Soil carbon pool is an important component of the ecosystem carbon pools. It plays a key role in mitigating the global warming and control the concentration of greenhouse gas. The areas of urban land have changed dramatically both in quality and quantity due to the land-based urbanization and industrialization. This paper analyzed the change of the soil organic carbon reserves under the land use change in Tianjin Binhai New Area (TBNA) from 1995 to 2012. The results showed that the land use change was one of the important reasons of the soil organic carbon change, and the soil organic carbon reserves of land use change in TBNA was reduced from3.339mt (million ton) to 5.842mt in this stage.

Abstract. Accurate estimation of soil organic carbon (SOC) storage and determination of its pattern controlling factors is critical to understanding the ecosystem carbon cycle and ensuring ecological security. The Sanjiang Plain of China, an important grain production base, is typical of ecosystems, yet the SOC storage and pattern of this region has not been fully investigated because of the deficient soil investigations. In this study, 419 soil samples and a geostatistical method were used to estimate the total SOC storage and density (SOCD) of this region with the former being 2.324 Pg C, and the latter value being higher than the mean value for the whole country. The SOCD was found to have notable changes in spatial and vertical distribution. In addition, the vegetation, climate, and soil texture, as well as the agricultural activities, were demonstrated to have remarkable impacts on the variation of SOCD. Soil texture had stronger impacts on the distribution of SOCD than climate in the Sanjiang Plain. Specifically, the clay content explained the largest proportion of the SOC variation and was thus the most dominant environmental controlling factor. As far as climatic factors are concerned, precipitation exhibited more significant effects on SOCD than temperature. In addition, the effects of both climate and soil texture on SOCD were reduced with increasing soil layer depth. The results from this study provide the most updated knowledge on the storage and pattern of SOC in the Sanjiang Plain, and the analysis conducted here could contribute to the determination of ecosystem carbon budgets and understanding of ecosystem services.

Abstract An experiment of different application rates of biochar and biochar combined with nitrogen fertiliser was conducted at experimental field on a Haplic Luvisol located in Nitra region of Slovakia during the growing season of spring barley (2014). The aim of this study was to evaluate the effects of biochar and biochar combined with nitrogen fertilisation on the soil organic carbon (SOC). The treatments consisted of 0, 10 and 20 t/ha of biochar application (B0, B10 and B20) combined with 0, 40 and 80 kg/ha N of nitrogen fertiliser applied (N0, N40 and N80). The results showed that SOC content at the beginning and end of the trial was always higher at the plots amended with biochar as compared to control plots (B0N0, B0N40 and B0N80); however, statistically significant effects were observed only at the beginning of the trial as well as at the end of trial in B20N40 treatments. Overall, the highest values of SOC contents were obtained at the beginning as well as at the end of the trial when 10 and 20 t/ha of biochar was applied together with 40 kg/ha N.
