- Abstract
Modern agriculture has become a real source of pollution; the systematic use of chemical fertilizers and pesticides at high levels often has multiple consequences on the environment, as in the case of the Bounamoussa plain “El Tarf-Algeria” (which is highly productive and is known for the diversity of its crops and for cultivation practices that call for the use of chemical fertilizers and phytosanitary products, as well as the use of irrigation water from different sources and of often unknown quality. The lack of evaluation of the state of soil fertility and the risks generated by cultivation practices justifies such a study and proposes a follow-up by the services concerned. The approach adopted consists of an analysis of the soil and drainage water collected at the end of the summer season. The aim is to evaluate in a preliminary way the pollution of surface waters and soils of the plain of Bounamoussa. The results of the physico-chemical analyses of the soil and water reveal the existence of excessive levels of phosphates and chlorides, which becomes a risk of salinization of the soil. The presence of high levels of nitrites and nitrates can be a potential risk of pollution of groundwater.
