ABSTRACT:
In the present
work, we were able to verify the utility of splitting the organic matter that
seems to be indispensable, especially when it comes to the soil humus which is
very little polymerized and containing a large proportion of non-decomposed
organic matter. This study even if it remains unfinished, it provides some
useful information. Moreover, this work reflects the fundamental influence
exerted by the organic matter as a soil and as a driving force of its dynamics.
Humus factor in the vocation of a soil can promote or remove some plant
species. The statistic analysis shows that the humification of the organic
matter is faster on calcareous sandstone substrate (Calabrien) as on Tithonique
Substrate with advanced cretaceous which can be explained by the very high rate
of humic acids as the calcareous sandstone substrate. At the level of plant
development, the organic matter provided by the mixed stands (Eucalyptus,
Pinus halepensis, Juniperus phoenicea) with an undergrowth which is formed
by (Retama monosperma,calycotome spinosa,Pistachia lentiscus,
Phylaria latifolia, Lavandula stoecka) has a very god humification with a
predominance of humic acids that indicate the acceleration of the development
of clay-humic complexes and a permanent wealth of energy reserves.
