Three particle-size fractions (PSFs) were separated (AS 12893.6.1, Standards Australia 2009): 2000-200 [micro]m (including particulate OM, coarse sand and macroaggregates, referred to hereafter as the 'macro' fraction); 200-60 [micro]m (medium sand and microaggregates, referred to hereafter as the 'micro' fraction); and <60 [micro]m (fine sand, silt and clay, referred to hereafter as the MAOM fraction) (Hobley et al.
The macro fraction consistently had lower SOC concentrations than the bulk samples; the micro fraction and MAOM fractions had higher SOC concentrations than the bulk samples.
In the micro and MAOM fractions Ef was >1, similar at all depths and showed no trend.
The oldest radiocarbon ages were consistently in the macro fraction; the micro and MAOM fractions were younger and had similar ages.
