This study aims to determine the relationships likely to exist between the edaphic variables and the abundance of oak species in the Edough forest of the commune of Seraidi (North East of Algeria), a humid bioclimatic stage where rainfall is abundant. In order to characterize the properties of the soils of the Edough forest (Seraidi) and to verify the usefulness of the fractionation of organic matter in a forest ecosystem, we have established a prospecting sampling plan based on a topographic background of the superposition of the different plant groups. In this context, the approach we adopted consisted on three main steps (i) a stratified sampling of the soil, (ii) the determination of the different strata of vegetation, (iii) describing the soil on which these plant formations settle and develop. Our results revealed that the soils of the Edough forest are acidic to very acidic and non-saline. It is also characterized by clayey texture that is not very permeable, with a high rate of organic matter, which controls the buffering capacity of the soil. The characterization of the soils allowed determining three types of plant formations and thus three types of soils where pedogenesis is under direct control of the supply of organic matter. The relationship between the soil and the vegetation in this forest is clearly close. It is mainly controlled by the supply of organic matter, which shows a significant dynamic and evolution. On the other hand, the climatic conditions and the type of plant formations have a capital role in the mineralization of the existing organic matter. [ABSTRACT FROM AUTHOR] |
