Soil organic carbon fractionation and metagenomics pipeline to link carbon content and stability with microbial composition

Society needs to capture gigatons of carbon dioxide from the atmosphere annually and then store it long-term to limit and ultimately reverse the effects of climate change. Bringing lost carbon back into agricultural soils should be a priority as it brings the added benefit of improving soil properties. Linking soil organic carbon (SOC) fractions of different stability with soil microbial composition can help understand and subsequently manage SOC storage.

为限制并最终扭转气候变化的负面影响，全球社会每年需从大气中捕获数十亿吨二氧化碳并开展长期封存。将流失的碳重新返还至农田土壤应作为优先事项，因其还可带来改善土壤性状的额外益处。将不同稳定性的土壤有机碳（soil organic carbon, SOC）组分与土壤微生物群落组成相关联，有助于理解土壤有机碳的封存过程并进而对其进行调控管理。
