The aim of current research was to study some diagnostic characteristics
/morphological, physical, chemical/and the origin structureofforest soils in Syrian coastal
region. In addition to estimation of microbial activity of some microbial groups/ba
cteria,
fungi, actinomycete/ to establish a general view of these soils.
Two complete sections were prepared in the considered soils /Safita-Tartous/
andsamples were taken after the soils sections description for diagnostic characterization.
The results showed that the soil pH was between neutral and tiny basic and because
of the richnessof the studied soil by calcium carbonate. However, the highest percentage of
organic matter in all sections were concentrated in the surface horizon and was decreasing
with depth. Our results also showed that the microbial activity was positively correlated
with the content of the organic matter and negatively with the depth, so the total number of
bacteria and fungi was decreasing in the under surface horizon. A
muddymetamorphosedhorizon (Bm) was formed in the two sections.
In order to evaluate the important role of climate on soil formation, three
different locations (Nawa, Dael and Nasib) in southern part of Syria,
representing the North West, Middle and Southern parts of Hauran Plateau
were selected and differ mai
nly in the amount of annual precipitation and
relatively with other factors. Three profiles, replicated three times, were
prepared one profile for each area.
