Bio-Revegetation Impact on the Physicochemical Characteristics of a Sandy Quarry Soil in Terga Beach Region in Algeria

In order to define the impact of a bio-revegetation effect on soil physicochemical properties, we used Acacia Saligna in variants with bio-fertilizers such as rhizobia and mycorrhizae that play a key role in the productivity and sustainability of soil as well as the environmental protection. The area of study is a degraded sandy quarry in Terga, a coastal semi-arid area located in the northwestern part of Algerian. Our sampling and analysis of soil were made after each trimester of experiments in the fields, using four blocks, each one containing ten plots. Sampling is a composite of soil that was made in each plot diagonally on a depth of 10 cm and a diameter of 30 cm from the plant, at different times- first trimester (3 months), second (6 months), and third (9 months). Preliminary results showed a real and favorable modification of substrates by obtaining materials with less alkaline pH, there is a significant phosphorus increase in the second and third trimester compared to the first trimester, however the soil calcareous nature prevents the expression of some parameters resulting in a small improvement in total nitrogen and a deficiency in both exchangeable magnesium and organic matter.
