Prétraitement Des Échantillons Pour Analyse Du Sol Des Formations Végétales A Marrubium Vulgare L. A Hammam Bouhadjar (wilaya D’ain Témouchent).

Résumé: The species Marrubim vulgare L, and among the medicinal plants identified among the populations and benefiting from good therapeutic reputations and which will therefore have to be put to the test of serious investigations of chemical and biological decryptions. It is also found in western Algeria and develops in the mountains, forests and highlands; it also grows on rocks, pastures and crops. The aim of the study is to contribute to the knowledge and identification of the main physical and chemical characteristics of the soils occupied by the species Marrubium vulgare L. in the commune of Hammam bouhadjer, wilaya of Ain Témouchent. And to try to highlight the soil- vegetation relationship that could characterize them and how to conserve. The results of the study showed that Marrubium vulgare L. develops on soils with a balanced texture, more precisely silty and limono-sandy, those soils that have significant limestone contents (total limestone), and a very low assimilable limestone fraction, the soils are unsalted with moderately basic pH. The CPA has allowed us to identify and confirm the soil conditions that favor the existence and development of this species.
