Brassica juncea is a high biomass crop species, whose suitability for phytoremediation of copper mine tailings amended with technosol has been recently documented. Although soil water availability is a parameter of critical importance, not much has been reported about its effect on phytoremediation. In this study, six treatments comprised by the combination of two mine soil-technosol mixtures and three soil moisture regimes were used to evaluate the influence of soil moisture on the growth of B. juncea in the amended mine soil, and assess its impact on phytoremediation. The results suggest that higher soil moisture improves the growth and development of B. juncea in copper mine soils amended with technosol, favoring the accumulation of greater amounts of Cu and Zn in the shoots and consequently, the phytoremediation of these soils.
