fulvichumiclike
Fulvichumiclike refers to dissolved or colloidal natural organic matter that displays a blend of fulvic-like and humic-like properties. The term is used in some environmental and soil science literature to describe substances that do not fit neatly into the standard fulvic or humic acid categories but share features of both, particularly in terms of molecular weight, polarity, and functional-group content.
Chemically, fulvichumiclike materials are heterogeneous and variable in composition. They are rich in carboxyl, phenolic and
Natural sources include soil organic matter, peat, lignite, compost extracts, and leachates from sediments. Fulvichumiclike substances
In soils and waters, fulvichumiclike matter influences nutrient availability, metal mobility, and the transport of hydrophobic
Because fulvichumiclike is not a single defined compound, identification relies on a combination of fractionation, spectroscopic
