Predicting and mitigating changes in soil carbon (C) stocks under global change requires a
coherent understanding of the factors regulating soil organic matter (SOM) formation and …

Soil organic matter (SOM) represents a major reservoir of stored carbon (C). However,
uncertainties regarding the composition and origin of stabilized SOM hinder the …

Humic acids (HA) are organic molecules that play essential roles in improving soil
properties, plant growth, and agronomic parameters. The sources of HA include coal, lignite …

Root exudates are an essential carrier for material cycling, energy exchange, and
information transfer between the belowground parts of plants and the soil. We synthesize …

Soil organic matter (SOM) and the carbon and nutrients therein drive fundamental
submicron-to global-scale biogeochemical processes and influence carbon-climate …

Minerals and organic matter (OM) may form intricate associations via myriad interactions. In
soils, the associations of OM with mineral surfaces are mainly investigated because of their …

In tropical regions, climate conditions favor fast decomposition of soil organic matter (SOM),
releasing into the soil organic composts in solid, liquid, and gaseous forms with variable …

Plant roots contribute substantially to the formation of stable soil organic matter (SOM), and
there is evidence that species differ in their contribution to SOM stabilization. However, it …

This contribution critically reviews the state of knowledge on interactions of natural colloids
and engineered nanoparticles with natural dissolved organic materials (DOM). These …

There is a growing concern about climate change, and soils have attracted significant
research attention as a sink for atmospheric CO 2. Mechanisms of soil organic carbon (SOC) …
