THE BIOFERTILISATION OF SALINE SOIL BY PHYTOREMEDIATION METHOD ATRIPLEX (HALIMUS, NUMMULARIA) IN IMPROVING THE PHYSICAL AND CHEMICAL PROPERTIES
This work aims to study the use of Atriplex nummularia and Atriplex halimus and in improving the physical and chemical properties of saline soil. The experiment was conducted under greenhouse and involves the application of 5 doses of NaCl (75, 150, 300, 600 Mm) used soil samples were analyzed in the laboratory after 2 months of treatment. The results show that the increase in the values of certain physicochemical parameters such as their EC, moisture, Na+ and K+ of the ground with the increase in the NaCl amounts, at the same time to announce the reduction in recorded total porosity appearing of both Atriplex Montre that at A.nummularia, the results obtained on the measured characteristics made it possible to note that the increase in the amounts of salinity caused the rise in the moisture and content of K+ of the ground, on the other hand we recorded a reduction in porosity at the same time, of THIS and of content of Na+ of the grounds on the other hand A.halimus, one notes an important effect on the increase of porosity, the EC and the content of Na+ of the ground and with a reduction in moisture and the content of K+. The species of Atriplex nummularia is characterized by an improving effect, soil characteristics (EC, pH, porosity and soil moisture).
