“…Unlike pH or the carbon content, the soils exhibit no significant differences in eCEC with parent material or vineyard type. Overall, these eCEC values are very low but similar to those previously reported for vineyard soils in the vicinity of the studied area (Arias et al, 2004;Nóvoa-Muñoz et al, 2007).…”

We studied total Cu content and its distribution in 33 surface soil samples cultivated with vines for variable lengths of time in the Monterrei designation of origin (DO), located in Galicia (NW Spain). The study was focused on the influence of land use changes on soil degradation by effect of Cu accumulation and availability. Total copper concentration in soils ranged from 25 to 272 mg kg À1 . The time during which each soil was cultivated with vines was found to affect both the total concentration of copper and its distribution. The average concentration of copper in young vineyards was 64 mg kg À1, whereas those in old and abandoned vineyards were 100 and 132 mg kg À1 , respectively. Copper bound to organic matter and to amorphous inorganic colloids were greater in old and abandoned vineyards, where they accounted for 51 and 52 per cent, respectively, of total copper, than in young vineyards (39 per cent). Copper bound to crystalline Al and Fe colloids accounted for 21, 22 and 12 per cent of total Cu in old, abandoned and young vineyards respectively.The prevalence of Cu bound to the organic fraction reduces the adverse environmental effects of this metal on soil organisms and plants. However, some management practices such as organic matter addition or liming should be implemented in order to delay or avoid soil degradation in young vineyards. For abandoned vineyards, the influence of new land uses on potential Cu mobilisation necessitates careful examination.

“…A toxicity threshold was established only in light textured soils, for nonbearing potted grapevine (Toselli et al 2009) and pear (Toselli et al 2008) plants at a concentration of DTPA-extractable Cu > 141 and 350 mg/kg respectively, while in clay-loam soils, both the fruit species showed the possibility to tolerate levels of DTPA-extractable Cu as high as 1000 mg/kg with no symptoms on shoot growth. Total Cu concentration was similar to that found in a Haplic Cambisol near Prague (Komárek et al 2008), and in several vineyard soils of Victoria, Australia (Pietrzak and McPhail 2004), but lower than the concentrations found in Northern Spain by Nóvoa-Muñoz et al (2007). Most of the investigated soils presented a total Cu concentration below the Italian legislative (DL 99/92) limit of 100 mg/kg (value above which the application of sewage sludge is not allowed), but above the warning limit valid in the EU, i.e.…”

“…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.

“…The total content of copper and its distribution among vineyard soil components including clay, oxides and organic matter have been the subject of several recent studies (Chaignon et al, 2003;Arias et al, 2004;Pietrzak and McPhail, 2004;Nóvoa-Muñoz et al, 2007), and so has the distribution of the metal among grain size fractions (Arias et al, 2005) and the sorption-desorption processes that govern its changes in this type of soil. However, spatial distribution in the copper distribution in vineyard soil has scarcely been studied, even though it is crucial with a view to developing and implementing effective farming practices to prevent land degradation due to excessive accumulation of copper in the soil while ensuring sustainable development of crops for many years.…”

Short‐scale distribution of copper fractions in a vineyard acid soil

et al. 2007

We studied short-scale variation in the total concentration of copper and its fractions in a soil vineyard. Soil samples were collected at a depth of 0-20 cm between plant rows (1), between individual plants (2) and at their base (3) in a vine-grown plot in NW Spain. The mean total content in Cu (Cu t ) in the soil was found to be 97 mg kg À1 and that of potentially available Cu (Cu EDTA ) 34 mg kg À1 . Copper bound to organic matter (Cu OM ) and to non-crystalline inorganic soil components (Cu IA ) were the dominant fractions and accounted for 34% of total copper each. The contents in exchangeable (Cu e ), pyrophosphate-extractable (Cu p ), oxalic/oxalate-extractable (Cu o ) and total copper (Cu t ) exhibited statistically significant correlations with pH, sum of base cations (S), cation-exchange capacity (CEC) and exchangeable calcium (Ca e ). Both total and fractional copper contents were higher in plant rows than between them, particularly in the centre of the plot. Also, Cu OM and Cu IA were higher in planting rows than between rows. These copper results may have been influenced by the vine-growing practices of the area and also by the distribution of plants and their pruning. This variability pattern for Cu distribution is crucial with a view to minimising potential adverse effects of fungicides and optimising any reclamation treatments needed.
