Dissolved organic matter (DOM) is a heterogeneous mixture of organic compounds that
plays an important role in the movement of DOM-associated pollutants. In this study,
transport and fractionation of DOM in soils was investigated in flow-through soil columns.
Dissolved organic matter derived from spent mushroom substrate weathering was pumped
through packed columns (2.5 cm× 10 cm) comprising a coarse-loamy subsoil (mixed,
semiactive, mesic Typic Hapludult), and effluents were monitored for changes in the …
