BRUNETTO, GUSTAVO et al. HEAVY METALS IN VINEYARDS AND ORCHARD SOILS. Rev. Bras. Frutic. [online]. 2017, vol.39, n.2, e-263.  Epub 03-Jul-2017. ISSN 0100-2945.  http://dx.doi.org/10.1590/0100-29452017263.

The application of foliar fungicides in vineyards and orchards can increase soil concentration of heavy metals such as copper (Cu) and zinc (Zn), up to the toxicity threshold for fruit trees and cover crops. However, some agronomic practices, such as liming, addition of organic fertilizers, cultivation of soil cover crops and inoculation of young plants with arbuscular mycorrhizal fungi can decrease the availability and the potential of heavy metal toxicity to fruit trees. This review aims to compile and present information about the effects of increasing concentrations of heavy metals, especially Cu and Zn, on soils cultivated with fruit trees and provides some agronomic practices of remediation. Information about the sources of heavy metals found in soils cultivated with fruit trees are presented; mechanisms of absorption, transport, accumulation and potential toxicity to plants are described.
