copper and zinc in rhizospheric soil of wild plants growing in long term acid Vineyard Soils insights on availability and metal remediation
Science of The Total Environment, 2019Co-Authors: Claudia Campillocora, Paula Perezrodriguez, David Fernandezcalvino, Manuel Ariasestevez, Esperanza Alvarezrodriguez, Maria J Fernandezsanjurjo, Avelino Nunezdelgado, Juan Carlos NovoamunozAbstract:Abstract Total and available Cu and Zn levels were assessed in plant biomass, as well as in two rhizosphere fractions (tightly adhering rhizosphere (TAR), and loosely adhering rhizosphere (LAR)), in wild plants species from Vineyard Soils. Both TAR and LAR fractions were enriched in total Cu and Zn (1.7 and 1.6 times, respectively), and in available Cu and Zn (2.2 and 19.5 times, respectively), with the former being significantly higher for TAR than for LAR fractions. Mean values for total Cu accumulation in root and aerial biomass of the studied wild plants were 84 and 66 mg kg−1, respectively, being 57 and 79 mg kg−1 for Zn. No correlations were found among metal contents in plant biomass and available Cu and Zn concentrations in the rhizosphere fractions. Translocation factor (TF) values for Zn (range 1.0–3.5) indicate preferential accumulation in the aerial biomass in all the studied wild plants. On the contrary, TF for Cu shows a greater variability, depending on plant species, and ranging from 0.2 to 5.9. Regarding bioaccumulation factor (BAF), ranges were 0.03–0.27 and 0.13–0.58, for Cu and Zn, respectively. Results suggest that D. sanguinalis, P. hieracioides, S. viridis, and T. barbata could be useful for Cu remediation in the studied Soils, by means of phytostabilization processes.

nitrogen mineralization dynamics in acid Vineyard Soils amended with bentonite winery waste
Archives of Agronomy and Soil Science, 2018Co-Authors: Isabel Rodriguezsalgado, Antia Gomezarmesto, Paula Perezrodriguez, Manuel Ariasestevez, M Diazravina, Claudia Campillocora, Juan Carlos Novoamunoz, David FernandezcalvinoAbstract:ABSTRACTAn excess of available nitrogen (N) in Vineyard soil is considered detrimental for vine growth, making a thorough assessment of N mineralization dynamics in Vineyard Soils before the addition of winery waste necessary. This study assesses the changes in N mineralization in acid Vineyard Soils amended with bentonite winery waste (BW). Non-amended soil (control), BW and soil-waste mixtures (SBWM) with a low (+L) or high (+H) dose of BW were incubated for six weeks. After 7, 14, 21 and 42 days of incubation, the control Soils, BW and SBWM were analysed for net ammonified N, net nitrified N and net mineralized N. Parameters related to the kinetics of N mineralization were also determined. The addition of BW increased the potentially mineralizable N (N0) in the amended Soils (58–144% for the highest BW dose), although the mineralization rate was governed by the soil characteristics. Mineralizable N was only a small fraction (<4%) of the total organic nitrogen added to the soil through the BW addition, ...

retention of quaternary ammonium herbicides by acid Vineyard Soils with different organic matter and cu contents
Geoderma, 2017Co-Authors: M Condecid, David Fernandezcalvino, Juan Carlos Novoamunoz, Remigio Paradelo, Cristina Pereznovo, Manuel AriasestevezAbstract:Abstract Adsorption and desorption of quaternary ammonium herbicides (paraquat, diquat, and difenzoquat) has been studied in four acid Vineyard Soils with a range of organic matter and copper contents, in order to assess the influence of copper on herbicide adsorption. Adsorption at equilibrium has been studied in batch experiments, and kinetics have been studied in a stirred flow chamber. Adsorption and desorption kinetics were well described by the pseudo-first-order model. The retention capacity for the pesticides by the four Soils, based on the results of the batch experiments, followed the sequence: paraquat > diquat > difenzoquat. The different adsorption capacities of each soil were not related to pH, clay or organic matter contents, as could be expected, but rather to copper contents. The results show that, in Vineyard Soils with these characteristics, competition with Cu for adsorption sites is an important factor in quaternary ammonium herbicides retention.

copper content and distribution in Vineyard Soils from betanzos a coruna spain
Spanish Journal of Soil Science, 2015Co-Authors: Antia Gomezarmesto, Jessica Carballeiradiaz, Paula Perezrodriguez, David Fernandezcalvino, Manuel Ariasestevez, Juan Carlos Novoa Munoz, Esperanza Alvarezrodriguez, Maria J Fernandezsanjurjo, Avelino NunezdelgadoAbstract:The sustained use of cupric compounds in grape production has contributed to a pronounced Cu accumulation in Vineyard Soils. We studied 32 surface (0-20 cm) Vineyard soil samples from the Atlantic-influenced NW Iberian Peninsula, in order to assess the Cu levels in these Soils. The total Cu (CuT) contents were high and variable (between 63-730 mg kg-1), similar to those previously found in the Ribeira Sacra and O Ribeiro denominations of origin, which were until now the areas with the highest CuT concentrations detected in Vineyard Soils of the NW Iberian Peninsula. Most Cu in the solid phase of the soil was bound to organic matter (18-373 mg kg-1), contrary to what happens in natural Soils or with elements from natural sources, such as Zn, for which the residual fraction is quantitatively the most important. The exchangeable Cu fraction was the fraction that showed the highest geochemical mobility and its variance in the studied Soils was mainly related to CuT and, secondly, to exchangeable Ca levels. The results of fractionation were clearly different from those of Zn, an element with a mainly natural origin, which was characterized by a dominant residual fraction. Finally, agricultural practices aimed at maintaining or increasing the amount of organic matter in Vineyard Soils should be encouraged, due to its role in decreasing the eventual toxic effects of high Cu levels both on plants and on soil microorganisms.

respiration parameters determined by the iso 17155 method as potential indicators of copper pollution in Vineyard Soils after long term fungicide treatment
Science of The Total Environment, 2013Co-Authors: Pedro Solerrovira, David Fernandezcalvino, Manuel Ariasestevez, Cesar Plaza, Alfredo PoloAbstract:This study seeks to determine the impact of copper-based fungicides on the respiration of Vineyard Soils. The ISO-17155 is an international standard recommended for monitoring soil quality by the evaluation of the effects of pollutants on soil microbial activity. Respiration curves and derived parameters [i.e., basal respiration (RB), substrate-induced respiration (RS), lag time (tlag), growth rate (μ), time to the peak maximum (tpeakmax), respiratory-activation quotient (QR), and the cumulative O2 consumption (CR)] were determined from 95 Vineyard Soils that covered a wide range of Cu contents. Statistical analyses showed that most of the variance of the ISO-17155 parameters was due to soil pH and organic C content, but not to the Cu pollution. When the parameters were expressed as a function of soil organic C content, the effect of soil Cu content was found to be significant on RS and tpeakmax but not on RB and CR. The results indicated that threshold values of total (CuT) and exchangeable (CuEX) contents indicative of soil Cu pollution cannot be established. However, adequate management practices resulting in soil organic C contents>2% and pH>5.5 are recommended for preserving Vineyard soil quality.

chromium and fluoride sorption desorption on un amended and waste amended forest and Vineyard Soils and pyritic material
Journal of Environmental Management, 2018Co-Authors: Aurora Romargasalla, Manuel Ariasestevez, Esperanza Alvarezrodriguez, Avelino Nunezdelgado, Juan Carlos Novoamunoz, Vanesa Santasmiguel, Maria J FernandezsanjurjoAbstract:Using batch-type experiments, chromium (Cr(VI)) and fluoride (F-) sorption/desorption were studied in forest and Vineyard soil samples, pyritic material, pine bark, oak ash, hemp waste and mussel shell, as well as on samples of forest and Vineyard soil, and of pyritic material, individually treated with 48 t ha-1 of pine bark, oak ash, and mussel shell. Pine bark showed the highest Cr(VI) sorption (always > 97% of the concentration added) and low desorption (<1.5%). Pyritic material sorbed between 55 and 98%, and desorbed between 0.6 and 9%. Forest and Vineyard Soils, oak ash, mussel shell and hemp waste showed Cr(VI) sorption always < 32%, and desorption between 22 and 100%. Pine bark also showed the highest F- retention (sorption between 62 and 73%, desorption between 10 and 15%), followed by oak ash (sorption 60-69%, desorption 11-14%), forest soil (sorption 60-73%, desorption 19-36%), and pyritic material (sorption 60-67%, desorption 13-15%), whereas in Vineyard sorption was 49-64%, and desorption 24-27%, and in hemp waste sorption was 26-36%, and desorption 41-59%. Sorption data showed better fitting to the Freundlich than to the Langmuir model, especially in the case of Cr(VI), indicating that multilayer sorption dominated. The addition of by-products to the forest and Vineyard Soils, and to the pyritic material, caused an overall increase in F- sorption, and decreased desorption. Furthermore, the pine bark amendment resulted in increases in Cr(VI) retention by both Soils and the pyritic material. These results could be useful to favor the recycling of the by-products studied, aiding in the management of Soils and degraded areas affected by Cr(VI) and F- pollution, and in the removal of both anions from polluted waters.

pesticide residues in Vineyard Soils from spain spatial and temporal distributions
Science of The Total Environment, 2015Co-Authors: Eva Posejuan, M J Sanchezmartin, Sonia M Rodriguezcruz, Soledad M Andrades, Eliseo HerrerohernandezAbstract:Spatial and temporal evaluations of seventeen pesticides and some of their degradation products were carried out in seventeen Vineyard Soils from La Rioja region (Spain). The Soils were sampled in March, June and October 2012, and the pesticides were selected among those previously detected in surface and ground waters from the same area. All pesticides were detected in some of the Soils in the three different areas of La Rioja at the different sampling times, with only the metalaxyl metabolite, CGA-62826, not being detected in any of the Soils sampled in October. The highest concentrations were determined for the fungicides metalaxyl (11.5 μg kg(-1)) and triadimenol (26.1 μg kg(-1)), the herbicides fluometuron (174.6 μg kg(-1)) and terbuthylazine (403.3 μg kg(-1)), and the insecticide methoxyfenozide (4.61 μg kg(-1)). While the highest total concentration of pesticides was detected in March, the highest number of positive detections was recorded in June (46), as opposed to 26 and 19 in March and October, respectively. Significant differences were detected in the concentrations of herbicides in Soils from the three areas in La Rioja, but this was not the case for the fungicides and the insecticides. The study revealed a more intensive use of herbicides in March, while the use of insecticides and fungicides probably depended on the specific needs of crops and/or the onset of diseases. The results are consistent with the residues found in waters in the region, and highlight the need to implement strategies for more efficient application of these compounds to avoid risk of water contamination.

development of a procedure for the multiresidue analysis of pesticides in Vineyard Soils and its application to real samples
Journal of Separation Science, 2014Co-Authors: Eva Posejuan, M J Sanchezmartin, Eliseo Herrerohernandez, Alba Alvarezmartin, Sonia M RodriguezcruzAbstract:A procedure for multiresidue analysis was developed for the extraction and determination of 17 pesticides, including herbicides, fungicides, and insecticides, as well as certain degradation products, in Vineyard Soils from La Rioja region (Spain). Different solvents and mixtures were tested in spiked pesticide-free Soils, and pesticides were comparatively evaluated by gas chromatography with mass spectrometry and liquid chromatography with mass spectrometry. Recoveries >70%, with relative standard deviations <9%, were obtained when a mixture of methanol/acetone or a mixture of methanol/CaCl2 0.01 M for the most polar compounds was selected as the extraction solvent. Method validation was accomplished with acceptable linearity (r(2) ≥ 0.987) within the concentration range of 0.005-1 μg/mL corresponding to 1.667-333.4 μg/kg and 0.835-167.1 μg/kg for liquid chromatography with mass spectrometry and gas chromatography with mass spectrometry, respectively, and detection limits <0.4 μg/kg for the compounds were studied. The extraction method was applied to 17 real Vineyard soil samples, and terbuthylazine and its metabolite desethylterbuthylazine were the most ubiquitous compounds, as they were detected in the 100% of the Soils analyzed. The presence of fungicides was also high, and the presence of insecticides was lower than other pesticides. The results confirm the usefulness of the optimized procedure for monitoring residues in Vineyard Soils.

effect of spent mushroom substrate amendment of Vineyard Soils on the behavior of fungicides 1 adsorption desorption of penconazole and metalaxyl by Soils and subSoils
Journal of Agricultural and Food Chemistry, 2009Co-Authors: Jesus M Marinbenito, M J Sanchezmartin, Soledad M Andrades, Margarita Perezclavijo, Sonia M RodriguezcruzAbstract:The effect of the addition of fresh and composted spent mushroom substrates (F-SMS and C-SMS) to Vineyard Soils on the adsorption−desorption of penconazole and metalaxyl was studied under laboratory conditions. SMS is a promising agricultural residue as an amendment to increase the soil organic matter (OM) content. It may also modify the behavior of fungicides applied to Vineyards. Freundlich Kf adsorption constants of both fungicides by Soils and subSoils from three experimental plots unamended and amended in the field ranged between 2.78 and 13.4 (penconazole) and 0.14 and 0.67 (metalaxyl) with scant differences for unamended soil and subsoil. However, Kf values of amended Soils were higher than those corresponding to subSoils and generally higher than those of unamended Soils (up to 2.3 times for penconazole and 1.3 times for metalaxyl). The influence of SMS treatment (fresh or composted) was observed in the adsorption of the most hydrophobic fungicide penconazole. Simple and multiple correlations betw...

effect of spent mushroom substrate amendment of Vineyard Soils on the behavior of fungicides 2 mobility of penconazole and metalaxyl in undisturbed soil cores
Journal of Agricultural and Food Chemistry, 2009Co-Authors: Jesus M Marinbenito, Soledad M Andrades, Sonia M Rodriguezcruz, M J SanchezmartinAbstract:Mobility of fungicides penconazole and metalaxyl in unamended and amended Vineyard Soils with fresh and composted spent mushroom substrates (F-SMS and C-SMS) was studied. Experiments were performed in non-incubated and incubated (outdoors for 77 days) undisturbed soil cores under non-saturated flow conditions. Breakthrough curves (BTC) of metalaxyl leaching were delayed with regard to the tracer ion, and they showed an incomplete leaching in all soil cores after the addition of 2.5−4.5 pore volumes. A decrease of the maximum peak concentration in C-SMS Soils with regard to unamended Soils (up to 24-fold in Viana soil) and an increase in the fungicide retention by Soils (up to 8-fold in the first segment of Viana soil core) was observed. However, a decrease (up to 2.6-fold in Sajazarra soil) or an increase (up to 1.4-fold in Aldeanueva soil) of the maximum peak concentration in F-SMS Soils was observed. No leaching of penconazole was observed in all cases. After fungicide incubation in soil cores, the amou...

Simple and multiple correlations between soil and subsoil properties and adsorption constants indicated the influence of the OM on the adsorption of both fungicides, together with the clay, silt, and CaCO(3) content for metalaxyl and the pH for penconazole. The results revealed changes in the adsorption-desorption processes of these fungicides, which could give rise to a decrease in the mobility of metalaxyl (highly water-soluble) and an increase in the retention of penconazole (more hydrophobic). These effects could have an impact on surface and/or groundwater contamination.

Copper Phytoextraction and Phytostabilization by Brachiaria decumbens Stapf. in Vineyard Soils and a Copper Mining Waste
Open Journal of Soil Science, 2013Co-Authors: Robson Andreazza, Leandro Bortolon, Simone Pieniz, Flavio Anastacio De Oliveira Camargo, Elisandra Solange Oliveira BortolonAbstract:Brachiaria decumbens is a high biomass plant with great potential for phytoremediation of copper-polluted Soils. The current study aimed to evaluate B. decumbens plants for phytoextraction and phytostabilization use in two different copper contaminated Vineyard Soils and a copper mining waste. Also, the macro and micronutrients uptake were evaluated after plants growth in copper contaminated Soils. B. decumbens was cultivated in two Vineyard Soils (Inceptisol and Mollisol) and a copper mining waste for 47 days of growth in greenhouse. Then, B. decumbens’s nutrient uptake was evaluated, and it’s potential application in phytoremediation techniques for the phytoextraction and phytostabilization of copper contamination. B. decumbens exhibited high levels of biomass production at contaminated Soils and no negative effect on macronutrients uptake was found. Copper contaminated Soils affected micronutrients uptake by Brachiaria plants. This Brachiaria specie showed high potential on copper phytoextraction with accumulation of copper concentrations in the shoots and roots of 70 and 585 mg·kg −1 of dry mass, respectively, in the Vineyard Inceptisol soil, after 47 days of growth. Mollisol soil and copper mining waste also exhibited high copper concentration in the biomass in the entire plant with 371 and 466 mg·kg −1 , respectively. Although Brachiaria exhibited low levels of translocation factor for copper, this specie showed high potential for copper phytoextraction on Inceptisol, Mollisol and copper mining waste with 1900, 1156 and 1363 g·ha −1 of copper, respectively. In summary, B. decumbens plants showed high potential for copper phytoextraction and phytostabilization of copper on contaminated Vineyard Soils and copper mining waste.

Brazilian Journal of Microbiology, 2011Co-Authors: Benedict C Okeke, Simone Pieniz, Robson Andreazza, Flavio Anastacio De Oliveira CamargoAbstract:Vineyard Soils are frequently polluted with high concentrations of copper due application of copper sulfate in order to control fungal diseases. Bioremediation is an efficient process for the treatment of contaminated sites. Efficient copper sorption bacteria can be used for bioremoval of copper from contaminated sites. In this study, a total of 106 copper resistant bacteria were examined for resistance to copper toxicity and biosorption of copper. Eighty isolates (45 from Vineyard Mollisol, 35 from Inceptisol) were obtained from EMBRAPA (Empresa Brasileira de Pesquisa Agropecuaria) experimental station, Bento Goncalves, RS, Brazil (29o09'53.92''S and 51o31'39.40''W) and 26 were obtained from copper mining waste from Cacapava do Sul, RS, Brazil (30o29'43.48''S and 53'32'37.87W). Based on resistance to copper toxicity and biosorption, 15 isolates were identified by 16S rRNA gene sequencing. Maximal copper resistance and biosorption at high copper concentration were observed with isolate N2 which removed 80 mg L-1 in 24 h. Contrarily isolate N11 (Bacillus pumilus) displayed the highest specific copper biosorption (121.82 mg/L/OD unit in 24 h). GenBank MEGABLAST analysis revealed that isolate N2 is 99% similar to Staphylococcus pasteuri. Results indicate that several of our isolates have potential use for bioremediation treatment of Vineyards Soils and mining waste contaminated with high copper concentration.

Potential Phytoextraction and Phytostabilization of Perennial Peanut on Copper-Contaminated Vineyard Soils and Copper Mining Waste
Biological Trace Element Research, 2011Co-Authors: Robson Andreazza, Leandro Bortolon, Marcelo Giacometti, Dione Dinael Roehrs, Marcio Rodrigues Lambais, Simone Pieniz, Flavio Anastacio De Oliveira CamargoAbstract:This study sought to evaluate the potential of perennial peanut (Arachis pintoi) for copper phytoremediation in Vineyard Soils (Inceptisol and Mollisol) contaminated with copper and copper mining waste. Our results showed high phytomass production of perennial peanut in both Vineyard Soils. Macronutrient uptakes were not negatively affected by perennial peanut cultivated in all contaminated Soils. Plants cultivated in Mollisol showed high copper concentrations in the roots and shoots of 475 and 52 mg kg−1, respectively. Perennial peanut plants showed low translocation factor values for Cu, although these plants showed high bioaccumulation factor (BCF) for both Vineyard Soils, Inceptisol and Mollisol, with BCF values of 3.83 and 3.24, respectively, being characterized as a copper hyperaccumulator plant in these Soils. Copper phytoextraction from Inceptisol soil was the highest for both roots and entire plant biomass, with more than 800 mg kg−1 of copper in whole plant. The highest potential copper phytoextraction by perennial peanut was in Inceptisol soil with copper removal of 2,500 g ha−1. Also, perennial peanut showed high potential for copper phytoremoval in copper mining waste and Mollisol with 1,700 and 1,500 g of copper per hectare, respectively. In addition, perennial peanuts characterized high potential for phytoextraction and phytostabilization of copper in Vineyard Soils and copper mining waste.

bacterial stimulation of copper phytoaccumulation by bioaugmentation with rhizosphere bacteria
Chemosphere, 2010Co-Authors: Leandro Bortolon, Marcio Rodrigues Lambais, Benedict C Okeke, Robson Andreazza, George Wellington Bastos De Melo, Flavio Anastacio De Oliveira CamargoAbstract:Abstract Copper contaminated areas pose environmental health risk to living organisms. Remediation processes are thus required for both crop production and industrial activities. This study employed bioaugmentation with copper resistant bacteria to improve phytoremediation of Vineyard Soils and copper mining waste contaminated with high copper concentrations. Oatmeal plant ( Avena sativa L.) was used for copper phytoextraction. Three copper resistant bacterial isolates from oatmeal rhizosphere ( Pseudomonas putida A1; Stenotrophomonas maltophilia A2 and Acinetobacter calcoaceticus A6) were used for the stimulation of copper phytoextraction. Two long-term copper contaminated Vineyard Soils (Mollisol and Inceptisol) and copper mining waste from Southern Brazil were evaluated. Oatmeal plants substantially extracted copper from Vineyard Soils and copper mining waste. As much as 1549 mg of Cu kg −1 dry mass was extracted from plants grown in Inceptisol soil. The Vineyard Mollisol copper uptake (55 mg Cu kg −1 of dry mass) in the shoots was significantly improved upon inoculation of oatmeal plants with isolate A2 (128 mg of Cu kg −1 of shoot dry mass). Overall oatmeal plant biomass displayed higher potential of copper phytoextraction with inoculation of rhizosphere bacteria in Vineyard soil to the extent that 404 and 327 g ha −1 of copper removal were respectively observed in Vineyard Mollisol bioaugmented with isolate A2 ( S. maltophilia ) and isolate A6 ( A. calcoaceticus ). Results suggest potential application of bacterial stimulation of phytoaccumulation of copper for biological removal of copper from contaminated areas.
