Abstract

The increasing generation of industrial waste represents a significant environmental and economic challenge, with tannery sludge (TS) standing out as a potential forestry input. Therefore, this study aims to evaluate the effects of different TS concentrations on the morphological development and phytoremediation capacity of Pinus taeda seedlings grown in nursery conditions. The experiment was conducted in a completely randomized design, with seven treatments (control and TS at concentrations from 0.5% to 20%) and 385 experimental units. The evaluations included germination rate, height, collar diameter, shoot and root biomass, total biomass, Dickson Quality Index, and macro and micronutrient contents. The results indicated that TS concentrations up to 5% did not compromise seed germination or morphological parameters. At higher concentrations, reductions in shoot biomass and accumulation of metals such as Fe, Cr, Cu, and Mn were observed, especially in the roots. The chemical analysis showed that TS contributes essential nutrients but may also increase levels of potentially toxic elements. Thus, it is concluded that P. taeda is tolerant to TS and effective in phytoextraction, provided that the application of the residue is properly managed.
