Abstract
Recent publications show that macroaggregates (> 250 {mu}m) may consist of microaggregates (20-250 {mu}m) in soils, which contain organic colloids. Roots and hyphae have a potential role in the formation of macroaggregates. Fragments of roots and hyphae may serve as nuclei for smaller aggregates. This implicates that aggregate factions contain organic material of different characteristics. Especially humus in microaggregates may play a keyrole for the mobility of elements in the soil. E.g. radiocaesium extractability in the silt fraction of a Calcic Chemozem and soil-to-plant transfer was distinctly enhanced due to seven times higher C{sub org}-contents as compared to an Eutric Cambisol.
