Objectives Alkaline extracts from soils generate operationally-defined isolates that are referred to as “humic substances” but may not relate to a distinct molecular structure within the soil organic matter (SOM) matrix. This study examines wheth

Soil represents the largest reservoir of terrestrial organic C, and plays a critical role in global C cycling. In light of predicted climate change and a more unified approach to mitigate greenhouse gas emissions, the soil's ability to sequester C, a

Black C is an essential component of the terrestrial C pool and its formation is often credited as a CO2 sink by transferring the fast-cycling C from the atmosphere–biosphere system into slower cycling C in the geosphere. This study is the first mu

Black carbon (BC) is considered ubiquitous in soil organic matter (OM) and therefore plays an important role in soil biogeochemistry. Its complexity, particularly within environmental matrices, presents a challenge for research, primarily as a result

Structural characterization of organic matter (OM) is crucial in assessing its role in soils and sediments. In this study, humic acids (HA) were sequentially extracted from a compost and characterized in terms of their molecular, chemical, and struct
