“…Since this process is estimated in decades (Pietrzak and McPhail 2004), this response confirms the hypothesis that, in the investigated area, the same cultivations (pear orchard/vineyard) was adopted for a long time. In fact as much as 72% (at 0-20 cm-depth) and 83% (at 20-50 cm-depth) of the total Cu was inactive, indicating that most of the Cu added to the soil was retained almost irreversibly (Arias et al 2004).

The investigation was carried out in 2005, on 30 plots chosen in the Central-Eastern part of the Emilia Romagna region, and cultivated with pear, grapevine and vegetable crops under the organic management system. For each crop, 5 plots with a level of calcium carbonate > 10% and 5 plots with a level of calcium carbonate < 3% were selected. For pear and vine, soil analyses were performed at the depths of 0-20 cm and 20-50 cm, for vegetable at the depth of 0-50 cm. Organic matter content was higher in pear-cultivated plots, followed by grapevine and vegetable crops. Copper application rate, from 1998 to 2004, was higher in pear and grapevine than in vegetable plots. Soil total and DTPA-extractable Cu were higher in pear and grapevine than in vegetable-cultivated plots. Soil DTPA-extractable Cu concentration was higher in the upper horizon than at 20-50 cm soil depth. The increase of total Cu in pear and vine-cultivated plots was combined with the increase of soil inactive Cu.

“…For example, regarding the Cu in soils of traditional wine-growing regions of the world, 20 to 500 mg Cu kg -1 are reported in France (FLORES-VÉLES et al, 1996;BRUN et al, 1998); 35 to 600 mg kg -1 in Spain (ARIAS et al, 2004); 2 to 375 mg kg -1 in Italy (TOSELLI et al, 2009); 100 to 210 mg kg -1 in Greece (VAVOULIDOU et al, 2005) and 40 to 250 mg kg -1 in Australia (PIETRZAK;MCPHAIL, 2004). In most cases these Cu concentrations are related to foliar applications of copper fungicides and, often, may be toxic to plants.…”

“…Considering the physiological actions, there are a number of factors to consider like the mechanisms of absorption, transport and accumulation of elements in plant tissues. The primary mechanisms of toxicity are found at molecular, cellular and sub-cellular level; the secondary mechanisms of interference deal with functional processes of plants and homeostatic response mechanisms which, in some cases, lead to tolerance mechanisms to heavy metal (BARCELÓ;POSCHENRIEDER, 1992).…”

-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).

“…The total copper in the topsoil (20.5 mg kg −1 in VN2 and 62.4 mg kg −1 in VN3, Table 2) was considered to be at a median or low level compared to the levels reported in the literature or by government regulatory agencies. Studies performed in many wine regions of the world have reported maximum concentrations of Cu in vineyard soils ranging from 200 to greater than 600 mg kg −1 (Brun et al 1998;Arias et al 2004;Casali et al 2008) In Australia and New Zealand, a Cu concentration of 60 mg kg −1 in soils necessitates studies of the effect on the environment (ANZECC/NHMRC 1992), whereas the European community advocates that Cu concentrations should be maintained between 40 and 140 mg kg −1 in soils with a pH below 7.0 (Council Directive 86/278/EEC 1986). However, the low concentration of clay and organic matter found in the soils used in this study caused a low sorption capacity (Bradl 2004) and, therefore, a high Cu availability (Table 2).…”

Copper uptake, accumulation and physiological changes in adult grapevines in response to excess copper in soil

Aims This study investigated Cu uptake and accumulation as well as physiological and biochemical changes in grapevines grown in soils containing excess Cu. Methods The grapevines were collected during two productive cycles from three vineyards with increasing concentrations of Cu in the soil and at various growth stages, before and after the application of Cu-based fungicides. The Cu concentrations in the grapevine organs and the macronutrients and biochemical parameters in the leaf blades were analyzed.Results At close to the flowering stage of the grapevines, the concentration and content of Cu in the leaves were increased. However, the Cu concentrations in the roots, stem, shoots and bunches did not correlate with the metal concentrations in the soil. The application of Cu-based fungicides to the leaves increased the Cu concentrations in the shoots, leaves and rachis; however, the effect of the fungicides on the Cu concentration in the berries was not significant. The biochemical analyses of the leaf blades demonstrated symptoms of oxidative stress that correlated with the Cu concentrations in soil. Conclusions The increased availability of Cu in soil had a slight effect on the levels and accumulation of Cu in mature grapevines during the productive season and did not alter the nutritional status of the plant. However, increased Cu concentrations were observed in the leaves. The evidence of oxidative stress in the leaves correlated with the increased levels of Cu in soil.
