Chromolaena odorata is a noxious alien invasive weed species with an enormous impact on the terrestrial ecosystem. The allelopathic potentials of this have had little attention, leading to changes in soil properties and microbial communities. This study investigates impacts invasion gradients rhizospheric chemical response Mount Cameroon Region. Forty-eight samples at four different degrees (uninvaded, low degree invasion, moderate high invasion) based coverage within subplots areas were collected properties, load, phosphatases activities secondary metabolites evaluated. At medium-degree concentrations P, K Fe increased arbuscular mycorrhizal fungi (AMF) colonization enzyme activities.
