Peatlands only cover a minor fraction of the global terrestrial surface, but due to drainage, they are major contributors to carbon dioxide (CO₂) emissions from soils. Previous studies have shown that hydrological conditions, nutrient availability and anthropogenic disturbance play an important role in the mineralisation of organic matter. Furthermore, microbial turnover depends on peat quality, which is determined by its botanical origin and degree of transformation under natural conditions.

排水有机土壤的基质质量——对二氧化碳通量的影响

泥炭地仅占全球陆地表面的一小部分，但由于排水，它们是土壤中二氧化碳 (CO ₂ ) 排放的主要来源。先前的研究表明，水文条件、养分供应和人为干扰在有机质矿化中起着重要作用。此外，微生物的更新取决于泥炭的质量，这取决于泥炭的植物来源和自然条件下的转化程度。
