“…The reason was the electron configuration [Ar]3d 10 4s 1 of Cu and its high reactivity with the functional groups containing S and N, in addition to the carboxylic and phenolic acids of soil organic matter (Croué et al, 2003;Casali et al, 2008).…”

“…Therefore, these factors define Cu and Zn adsorption in the soil and are therefore found in different fractions in the soil, since naturally they are adsorbed at different energy levels (Casali et al, 2008;Girotto et al, 2010). However, the increase of Cu and Zn contents in the soil because of frequent pig slurry and deep litter applications may affect the distribution of their fractions in the soil.…”

SUMMARYSuccessive applications of pig slurry and pig deep litter may lead to an accumulation of copper (Cu) and zinc (Zn) fractions in the soil profile. The objective of this study was to evaluate the Cu and Zn forms and accumulation in a Sandy Typic Hapludalf soil after long-term application of pig slurry and deep litter. In March 2010, eight years after initiating an experiment in Braço do Norte, Santa Catarina (SC), Brazil, on a Sandy Typic Hapludalf soil, soil samples were collected from the 0-2.5, 2.5-5.0, 5-10 and 10-15 cm layers in treatments consisting of no manure application (control) and with applications of pig slurry and deep litter at two levels: the single and double rate of N requirement for maize and black oat (1)

“…This happens because of the unidirectionality of applications in plants, through rinsing of heavy metals from the leaves during rain or irrigation, the abscission of senescent leaves or the deposition of pruned branches on the soil (KOMÁREK et al, 2010;BRUNETTO et al, 2014b;MIOTTO et al, 2014). For example, in vineyards, for the preventive control of diseases, especially of downy mildew (Plasmopara viticola), 30 kg Cu ha -1 year -1 may be added to the production system through fungicides (CASALI et al, 2008). This amount can be even larger in years with high frequency and volume of water precipitation, which favors the occurrence of diseases.…”

“…For example, in soils with medium texture and with medium and high organic matter content in Serrra Gaúcha, State of Rio Grande do Sul, which is the largest wine-growing region in Brazil, CASALI et al (2008) reported that the application of copper fungicides in vineyards increased the total content and the fractions more bioavailable of Cu in soil, including in layer as deep as 0.20-0.40 m. Furthermore, the same authors (CASALI et al, 2008) stated that other portions of Cu were noted adsorbed onto the mineral fraction, and that most of the Cu, regardless of the adsorbent material, was easily desorbable and could be considered in rapid equilibrium with Cu in the solution. In this case, the toxicity to plants in vineyard (vines or cover crop species) is maximized.…”

“…This can lead to the complexation with heavy metals that present an electron configuration [Ar] 3d 10 4s 1 that allows a high reactivity with the organic matter functional groups containing S and N, as well as carboxylics and phenolics, which allows a high bound power and low dessorption (CASALI et al, 2008). On the other hand, the mineralization of organic waste produces molecules into the soil solution that can complex heavy metals (such as Cu) and reduce their bioavailability and therefore the toxicity, but can increase their mobility through soil profile, which is not always desirable (BRUNETTO et al, 2014b).…”

-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. Index terms: Trace element, phytotoxicity, growth, fruit trees. METAIS PESADOS EM SOLOS DE VINHEDOS E POMARESRESUMO -A aplicação de fungicidas foliares em vinhedos e pomares pode incrementar os teores de metais pesados, como o cobre (Cu) e o zinco (Zn), em solos e, quando em excesso, podem causar toxidez às frutíferas ou plantas de cobertura. Porém, algumas práticas agronômicas, como a calagem, adição de resíduos orgânicos, cultivo de plantas de cobertura do solo e inoculação de plantas jovens com fungos micorrízicos arbusculares (FMA) podem diminuir a disponibilidade e o potencial de toxidez de metais pesados às frutíferas. A presente revisão objetivou compilar e apresentar informações sobre os efeitos do aumento dos teores de metais pesados, especialmente, Cu e Zn, em solos cultivados com frutíferas e algumas práticas agronômicas de remediação. Ao longo do texto são apresentadas informações sobre as fontes de metais pesados, com enfase no Cu e Zn, em solos cultivados com frutíferas; mecanismos de absorção, transporte, acúmulo e potencial de toxidez às plantas. Além disso, são relatadas algumas práticas agronômicas viáveis para remediar o potencial de toxidez de metais pesados em solos cultivados com frutíferas. Com a adoção destas práticas se espera menor disponibilidade de metais pesados no solo, o que reduziria o potencial de toxidez às plantas, especialmente, em frutíferas jovens transplantadas em solos com alto teor de metais pesados, como o Cu e Zn, permitindo satisfatório crescimento, produção e composição de frutos. Termos para indexação: Elemento traço, fitotoxidez, crescimento, frutíferas.1 (Paper 226-15).
