Swine wastewater compost and arbuscular mycorrhizal fungi in the growth and accumulation of copper in Eucalyptus grandis

The objective of this work was to determine the influence of arbuscular mycorrhizal fungi (AMF) and swine wastewater compost (SWC) on the growth and accumulation of copper in Eucalyptus grandis cultivated in soil contaminated with copper. The experiment was conducted in a greenhouse for 120 days, using a completely randomized experimental design in a factorial arrangement (2 x 3), with and without 40% SWC (v: v) and three inoculation treatments with AMF (without fungus, Gigaspora margarita and Aucalospora colombiana), totaling six treatments with eight replicates in soil previously contaminated with 400 mg kg-1 of copper. The height, stem diameter, root and shoot dry mass, and root and shoot content, Dickson quality index and translocation, relative efficiency of treatments for height of the seedlings and mycorrhizal colonization were evaluated. The addition of SWC and Gigaspora margarita increased morphological parameters and quality of seedlings in contaminated soil.
