Abstract

In this experimental study we are interested in identifying some physicochemical characteristics that determine the quality of the soils of the plain of Annaba willaya, North East Algeria. In order to know the physicochemical properties of the soils of the plain of Annaba, we have based on a systematic sampling plan. Analytically, the results show that the studied soils revealed a degree of acidity ranging from 7.30 to 7.80, with a clayey texture, the electrical conductivity is variable between 692 and 2042 μs/cm², and a relatively strong rate of limestone, also, the porosity values are very variable, and variable organic matter contents (1.27 to 5.68) %. From the analytical results, we were able to classify the soil of the plain of Annaba, willaya of Annaba, North East Algeria, in the system of classification of French soils CPCS (1967), and these are soils belonging to the class of Mediterranean red soils.
