Dans les zones sahariennes, les conditions édapho-climatiques sont considérées comme un facteur limitant la distribution et la prolifération de la pédo-faune. La lombriculture, absente au Sahara, peut contribuer à valoriser les ressources agro-environnementales par l’utilisation des lombrics. Notre étude dans la région de Ouargla, vise à étudier l’impact des amendements organiques sur lombriculture pour définir les meilleures conditions d’élevage des lombrics et de proposer ainsi sur cette base des dispositifs fiables de lombriculture. Les résultats de l’étude des conditions de lombriculture montre que l’espèce Aporrectodea longa ne peut pas s’adapter avec les milieux de culture. Le milieu de culture à base de déchet de palmes et une faible quantité du fumier donne les meilleurs résultats par rapport aux autres milieux de culture. Cela nous a ramené à choisir Lumbricus terrestris dont le comportement semble s’adapter aux conditions pédoclimatiques de la région de Ouargla. A l’issu des résultats, nous proposons pour Ouargla les dispositifs en planches et en bacs cylindriques. L’estimation de biomasse produite de ces derniers révèle un rendement en lombric d’environ 6408 kg de VT/ha.
