L’Effet de l’Incorporation de la Matière Organique sur les Propriétés Physico-Chimique des Sol Salés de la Plaine de la Mina (Relizane)

Abstract

The aim of this work is to study the effect of the incorporation of organic matter on the physicochemical properties of the saline soils of the Mina Plain (Relizane). This study was carried out in the field in a private farm, located in the region of El Matmar (Relizane). In order to conduct our experimentation we divided the experimental block into two plots: the first plot concerns the "Witness" and the other plot concerns the "Treated" plot by the manure. We then positioned 03 sample profiles, at the level of each plot, for the follow-up of the experimentation. In each profile, using a soil auger, we sampled soil samples to a depth of 1 meter in increments of 25 cm (0-25 cm, 25-50 cm, 50-75 cm and 75 cm. -100cm). Thus, 48 soil samples were taken from two measurement campaigns. The samples underwent various physical and chemical analyzes, at the INSID laboratory of El Matmar (W. de Relizane). The interpretation of the results obtained made it possible to highlight the positive effect of the incorporation. Manure on the physical and chemical parameters of the soil by increasing the rate of organic matter and cation exchange capacity (CEC) .Bar cons no change was observed for the rest of the parameters studied soil.
