Abstract


In order to highlight the changes that are made at the level of the quality of agricultural soils in the Jorf Lasfar area after the installation of various industrial units, we conducted a sampling companion during October 2014. Samplings were carried out following two horizons (0-2,5cm) and (2,5-10cm) in three stations. To assess the quality of agricultural soils in the region, we performed the physic-chemical analysis through the determination of some indicators namely: stability in dry and in water, pH, calcium carbonate (CaCO3%), Organic Matter (MO%) and Electrical Conductivity (CE mS/cm). The results obtained allowed to show that the index of aggregate stability is comparable in the three stations and it is in average of 30,61%, the pH is mildly alkaline in all stations with an average of 8.09, the rates of organic matter are more than 3% on average, while the average values of CE are low and do not exceed 0.98mS/cm calcium carbonates record values that vary on average from 10,90% to 11,38% in surface.
