Abstract
We have developed a method to separate particulate organic matter (POM ) according to its location: outside or inside soil aggregates. Densim etric fractionation in a dense solution (d=1.6 Mg.m(-3)) was used to s eparate free POM from water-stable aggregates (POMe). Then, after disp ersion of the aggregates the occluded POM (POMi) was recovered by flot ation in water. Application of the method to silty cultivated soils sh owed that most of the POM and associated carbon occurred as POMi locat ed within stable macroaggregates.
