This ADVANCE Fellowship will focus on soil inorganic carbon storage in Mollisols, which are among the most important agricultural soils in the world. Cultivation of these fertile soils leads to great soil organic carbon loss but the effect of cultivation on soil inorganic carbon storage has not been studied. Attempts to decrease the atmospheric CO2 concentration require understanding of soil inorganic carbon and its role in potential sequestration of carbon through pedogenic carbonate formation in different soils, especially soils of great agricultural importance like Mollisols. This research will: (1) study the mechanisms of pedogenic carbonate formation and (2) examine the effects of cultivation on soil inorganic carbon storage. Research on soil inorganic carbon is crucial in understanding global carbon cycle and its relation to global climate change.

该ADVANCE奖学金将重点关注松软土的土壤无机碳储存，松软土是世界上最重要的农业土壤之一。 这些肥沃土壤的耕作导致土壤有机碳大量流失，但耕作对土壤无机碳储量的影响尚未见报道。 降低大气CO2浓度的尝试需要了解土壤无机碳及其在不同土壤中通过成壤碳酸盐形成潜在固碳中的作用，特别是具有重要农业意义的土壤，如软土。 这项研究将：（1）研究成壤碳酸盐形成的机理;（2）研究耕作对土壤无机碳储量的影响。 土壤无机碳的研究对于认识全球碳循环及其与全球气候变化的关系具有重要意义。
