All soils harbor microaggregates, ie, compound soil structures smaller than 250 µm. These
microaggregates are composed of diverse mineral, organic and biotic materials that are …

Lignin is a major component of soil organic matter and also a rich source of carbon dioxide
in soils. However, because of its complex structure and recalcitrant nature, lignin …

Soil is the largest terrestrial reservoir of organic carbon and is central for climate change
mitigation and carbon-climate feedbacks. Chemical and physical associations of soil carbon …

Paddy soils make up the largest anthropogenic wetlands on earth, and are characterized by
a prominent potential for organic carbon (C) sequestration. By quantifying the plant‐and …

Fractionation of soil organic carbon (SOC) is crucial for mechanistic understanding and
modeling of soil organic matter decomposition and stabilization processes. It is often aimed …

Identifying controls on soil organic carbon (SOC) storage, and where SOC is most
vulnerable to loss, are essential to managing soils for both climate change mitigation and …

The relationship between soil structure and the ability of soil to stabilize soil organic matter
(SOM) is a key element in soil C dynamics that has either been overlooked or treated in a …

Soil disturbance from tillage is a major cause of organic matter depletion and reduction in
the number and stability of soil aggregates when native ecosystems are converted to …

Mechanisms for C stabilization in soils have received much interest recently due to their
relevance in the global C cycle. Here we review the mechanisms that are currently, but often …

Dissolved organic matter (DOM) is defined as the organic matter fraction in solution that
passes through a 0.45 μm filter. Although DOM is ubiquitous in terrestrial and aquatic …
