This scheme allows subdividing soil microaggregates into four groups according to their stability to sonification, and the properties of organic and organo-mineral components: nonoccluded (free) organic matter (LFfr), occluded organic matter (L[F.sub.ooc] = L[F.sub.ooc1] + L[F.sub.ooc2]), organo-clay complexes (Clay), and residue (Res) see Figure 2.
In forest soil (Krymlov 2), almost 31% of carbon is represented by free organic matter (LFfr), whereas in the arable layer the share of this fraction is less than 15% of [C.sub.LF] (Table 6).
