Physicochemical Characterization of the Soil from the Naama Region: Western Algeria

The physicochemical properties of the soil play an important role in determining its fertility. The objective of our study is to determine the physicochemical parameters of the soil in the region of the wilaya of NAAMA (South-West of Algeria). The collected samples were analyzed for various parameters including soil pH, electrical conductivity (EC), organic matter content, moisture and nutrient content (nitrogen, phosphorus and potassium). The results showed that the soil of the NAAMA region had: i) a slightly basic to neutral pH range, ii) electrical conductivity values indicate moderate salinity levels, which can impact soil fertility and plant growth, iii) for organic matter we observe a considered concentration which can be explained by the transfer of organic compounds from organic industrial effluents. The results of our study provide much needed insights into the physicochemical properties of soils in the NAAMA region. These results serve as the basis for our doctoral thesis which focuses on the transfer of organic pollutants in the soil-plant system.
