Etat de dégradation de structure du sol de mazagran

Abstract

The general purpose of this research is to study the state of degradation and the structure of the ground of the region mazaghran and do the analyses of the ground. The tests done in this research are the pH, the equivalent humidity, the humidity of earth, the conductivity and the apparent density, the granulometry also the structural stability. In purpose of comparing the composition, the results of the carried out analyses are differents from a region to another so the humidity of the 1st ground is high (12.92%) than the second one (11.87%). The Ph of the two sapmles os ground is basic (is about 8) the conductivity of the ground is high in the 2nd ground (179.7). The apparant density of the 1st ground (2.45g/cm3) high than (2.27g/cm3) wich is the apparant density of the 2nd one (0.0003) the texture of two samples is clay sand
