This work aims to assessing the environmental quality of agricultural soils under vine and wheat cultivation in the area of Mohammadia-Benslimane (Morocco). 80 soil samples were collected and studied. The results have been studied and recorded on the agronomic parameters; show that the soil’s textures contain clay andthe values of pH are neutral to slightly acid in all stations. The electrical conductivity values are clearly higher in soils under wheat than in those under vine. The CaCO3 contents within the different studied soils are generally similar in all stations. Moreover, the organic substance rate seems to be more important in the soils under the wheat crops (2%) than in those under the vine crops (1, 7%). For the four analyzed elements: Cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn), the lead and the zinc present a high concentration in the vine yard Plots compared to those of the wheat. The concentrations of the Cadmium in a few stations exceed the standards (2 ppm) and can reach 10,37 ppm. The order of the average’s contents with the lead and the zinc are 20,12 ppm and 148,60 ppm, respectively. They are inadequate with the concentration standards for a normal soil, ie 100 ppm for pb and 300 ppm for zinc. As regards metallic pollution, its index increases, for the soil under the vine (it takes the values from 0.281 to 2.203).
