Weathering intensity and mineral association facilitate the accumulation of soil organic carbon along an alpine toposequence

Alpine and other cold region ecosystems store globally important soil organic carbon (SOC) stocks that are vulnerable to warming. Therefore, determining the mechanisms that regulate SOC persistence is key to identifying the susceptibility to loss. In this study, we examined how c...

Dissolved organic matter composition and mineral surface chemistry modulate organic retention and formation of mineral associated organic matter

The interaction between dissolved organic matter (DOM) and minerals governs OM stabilisation in soils. Heterogeneous composition of DOM and diverse mineral surface characteristics in soils make it challenging to determine reaction mechanisms at mineral-organic interfaces. To dete...
