Soil is the largest reservoir of terrestrial organic carbon. Most of the organic carbon in soils is preserved by association with minerals, however, the composition and stability of mineral-associated organic carbon remain poorly understood. The project will use novel and emerging techniques to discover the composition of organic carbon and stability of organic carbon present in mineral-organic associations in representative Australian soils. Expected outcomes include new knowledge necessary for emerging global carbon cycling models and improve future climate projections.

土壤是陆地有机碳最大的储存库。土壤中大部分有机碳是通过与矿物结合而保存的，然而，矿物结合有机碳的组成和稳定性仍然知之甚少。 该项目将使用新的和新兴的技术来发现有机碳的组成和有机碳的稳定性存在于矿物有机协会在代表性的澳大利亚土壤。预期成果包括新出现的全球碳循环模型所需的新知识，并改进未来的气候预测。
