Abstract
Plain Rémila is characterized by its agricultural north of the province, its geographical
position in the North Semi-arid bioclimatic stage, its plain topography, these large
underground water resources and the risk of soil salinization by the presence geological
formation contribute to the primary salinization, land development by different project, which
need huge efforts developed the plain.
The aim of our study was determined salinity in plain Remila have comparisent between the
results of two methods most used; saturated paste extract and aqueous extract 1/5, and are
having spatial distribution in the study area.
The analysis of the soils used for the determination of salinity is estimated regularly by
measuring the EC, TDS, pH and electrical conductivity. These parameters allow us to have a
global vision of soil salinity in the region and at the same time to a distribution map of Salty
Soil in the study area. Our results soils are classified into three class of soils that costituer
