“…However, these effects are highly dependent on copper concentrations and method of cultivation. For example, plants cultivated in nutritive solutions have higher copper toxicity by the elevated availability of elements and fast uptake by the roots (Mezzavilla & Neto, 2017,), while plants grown in soils present lower copper uptake by the strong adhesion of copper to soil particles and a host of soil-system biotic and abiotic relationships that can lead to less adverse effects on nutritional balance (Kelepertzis et al, 2015;Chua et al, 2019). Since our study was carried out with soil, it is possible that copper remained partially aggregated to the soil, suggesting that the concentrations uptake by both tree species were insufficient to cause nutritional imbalance in all measured elements.…”

This study was conducted to assess the physicochemical characteristics of urban forest soil contaminated by copper and the dynamics of macro-and micronutrients uptake by Schinus terebinthifolia and Eugenia uniflora seedlings. The seedlings received 0 (control), 60, 120, 180 or 240 mg Cu kg -1 soil applied to urban forest soil within São Paulo City, Brazil. Our results showed that K was reduced in Cu-contaminated soil used for S. terebinthifolia cultivation and that organic matter was higher in Cu-contaminated soil used for E. uniflora cultivation. Other physicochemical properties of soil remained unaltered. S. terebinthifolia presented nutritional imbalances in N, K and Mg on leaves, while E. uniflora presented nutritional imbalances in K on leaves and in S on roots. It can be concluded that copper contamination can negatively affect chemical and nutritional characteristics of urban forest soil, as well as the nutritional dynamics of S. terebinthifolia and E. uniflora.
