Aspen Soils Retain More Dissolved Organic Carbon Than Conifer Soils in a Sorption Experiment

open access: yesFrontiers in Forests and Global Change, 2020
The effect tree species have on soil organic carbon (SOC) has been hotly debated but, so far, few clear patterns have emerged. One example of a differing tree species effect on SOC are aspen forests in North America, which have been found to have more ...

Controls of Initial Wood Decomposition on and in Forest Soils Using Standard Material

open access: yesFrontiers in Forests and Global Change, 2022
Forest ecosystems sequester approximately half of the world’s organic carbon (C), most of it in the soil. The amount of soil C stored depends on the input and decomposition rate of soil organic matter (OM), which is controlled by the abundance and ...
