Caractérisation physico-chimique du sol entourant la zone humide du lac El-Maleh (Wilaya d’El-Menia).

Abstract

The objective of this work is to study the soil of Lake Maleh characteristics located in El-Menia, which is regarded as wetlands of international importance and classified according to Ramsar Convention. To achieve this goal, the soil has been sampled from the surface to the deepest possible horizon and we conducted at the laboratory level (analysis of the chemical weight of the soil and the electric conveyor..... etc.), the results show that the soil at the study site has a moderate alkaline pH. The results of the analysis of the upper lake's electrolyte show that it has a slightly salty soil as well as rich organic material compared to the lower lake with salty soil and less abundant organic material. The chemical weight analysis showed that it has a sandy clay texture in both lake basins.This study showed that the soil of the lake and the desert wet areas are organic poor soil with a clay texture.
