ABSTRACT: The objective
of this study is to determine the influence of soil physico-chemical factors on the spatial distribution of matorrals in the plain from Remchi
to Béni-Saf located in the western region of Algeria. This study informs us of the relationships that soil can have on the diversity
of matorrals. On the bioclimatic level, the region is characterized by semi-aridity
accentuating the phenomena of thérophysation. Soil analyzes carried out using known
methods (Stokes Particle Size Method, Electrometric Method for pH, 1/5 Extract Method
for Electrical Conductivity, Bernard Calcium Method for CaCO3, Anne Method
for Organic Carbon). The results show a textural diversity; sandy-muddy “Remchi”,
sandy “Rachgoun 1 and Rechgoun 2”, not far from Béni-Saf. The low clay content (Remchi:
Profile 1: Horizon 1: Clays 10%, Profile 2: Horizon
1: Clays 16%, Profile 3: Horizon 1: Clays 5%, Rechgoun: Profile 1: Horizon 1: Clays 3%, Profile 3: Horizon 1: 2% Clays and Horizon
2: 3% Clays) leads to poor structural stability leading to degradation of the soil
surface through erosion. The latter is revealed by the presence of small erosion
claws visible on these rough slopes or almost.
