Abstract

The climate of the Mediterranean regions constraints are very important in coastal environments. They are marked by water-stressed reinforced by exposure to wind and more intense sunlight and exposure to the spray that convey salts and pollutants. The objective of this study is to see the effect of the environmental pressures on forest soils of the coastal and continental area. To test our hypotheses, two distinct areas have been selected in the North West Algerian to define a gradient of increasing exposure to a combination of osmotic stress and soil and climate. First coastal zone is located in the forest of ‘Touant’ located 200 m from the sea and the second continental is located in the forest of “chaabet Derou” took place and is distant about 15 to 20 km from the sea. In each of these areas, five of 400 m2 and distant of at least 1 km sampling sites were selected with similar exposure. Our results showed that the concentrations of organic carbon (CO), total nitrogen (NT), report C / N, and the rate in organic matter (MO), are slightly higher level of the continental coastline area. Moisture and the capacity of these soils are virtually the same in both areas and this shows that all these parameters are independent of exposure to stress. Measures the conductivity and the microbial biomass point out the footprint of the littoral environment. This work to allowed to note that the degree of exposure to the spray changes on a local spatial scale the amounts of ions in soils. However, the microorganisms are not affected by exposure to stress and the osmotic pressure generated by the spray at the regional level.
