Répercussions de l’irrigation par les eaux usées épurées et leurs sous-produits sur la qualité des cultures cas des STEP d’Ain El Houtz

Abstract

Agricultural irrigation needs a lot of water currently is done from boreholes, i.e. significant consumption of groundwater whose use could reserve for other needs in this context that we are interested in a specific case which is monitoring the development of a fodder plant, alfalfa, irrigated by treated wastewater and using this water for irrigation. The reuse of treated wastewater for irrigation is an economical solution against water loss. The objective of this work is to follow the yield and quality of the culture irrigated by waste water The results of this work one study presents an agricultural and ecological environmental advantage and can irrigate several types and kinds of cultures and gives a good yield. Keywords: Wastewater rueuse, alfalfa.
