| Soils near mining centers usually have high heavy metal (HM) levels. It has been found that some plants associated with arbuscular mycorrhizal fungi (AMF) improve growth and tolerance to HM in soils. This symbiosis is a biological resource for degraded soil recovery. The objective of this study was to determine the effect of inoculating AMF (Glomus spp.) on alfalfa (Medicago sativa L.) growth in agricultural soils with different copper (Cu) levels for degraded soil recovery. To this effect, alfalfa seeds were grown in soils from the Catemu and Casablanca valleys and inoculated with AMF. Plant height, stem diameter, and number of leaves were measured weekly. Dry matter, mycorrhizal colonization, and Cu concentration in alfalfa plant tissues were measured... |
