Observation of these microaggregates in dry conditions in scannning electron microscopy showed morphological characteristics that are representative of microaggregates described earlier in many Ferralsols. The shrinkage for drying of initially water saturated microaggregates was studied using an environmental scanning electron microscope. Results showed very small shrinkage for the microaggregates usually studied. However, the shrinkage varies since the volume of dried microaggregates was found to be 93 to 99% of their volume when they are saturated.  aCerrado  aMatéria Orgânica  aMicrobiologia do Solo  aSolo1 aBROSSARD, M.1 aBRUAND, A.1 aGARREAU, H.  tComptes Rendus Geosciencegv. 336. p. 1017-1024, 2004.
