Geochemical characterization of elements in Vitis vinifera cv. Negroamaro grape berries grown under different soil managements

Abstract

The present geochemical study concerns the impact of viticultural practices in the chemical composition of the grape cultivar "Negroamaro" in Apulia, a southern Italian region renowned for its quality wine. Three types of soil management (SM), two cover cropping with different mixtures, and a soil tillage were considered. For each SM, the vines were irrigated according to two irrigation levels. Chemical composition of soil and of berries of Vitis vinifera cultivar "Negroamaro" were analyzed by X-ray fluorescence, inductively coupled plasma-mass spectrometry and multivariate statistics (linear discrimination analysis). In detail, we investigated major and trace elements behavior in the soil according to irrigation levels, the related index of bioaccumulation (BA) and the relationship between trace element concentration and soil management in "Negroamaro" grapes. The results indicate that soil management affects the mobility of major and trace elements. A specific assimilation of these elements in grapes from vines grown under different soil management was confirmed by BA. Multivariate statistics allowed to associate the vines to the type of soil management. This geochemical characterization of elements could be useful to develop fingerprints of vines of the cultivar "Negroamaro" according to soil management and geographical origin.

Methods for Nutrient Diagnosis of Fruit Trees Early in the Growing Season by Using Simultaneous Multi-element Analysis

“…Nonetheless, a full 34component ionomic signature of the grape berries did not fully allow the discrimination of their geographical origin, most likely owing to heterogeneity in the vineyards and the limited number of samples analyzed (Pii et al, 2017). In addition, geochemical characterization of both major and trace elements could be useful in developing fingerprints of vines according to soil management (cover cropping, soil tillage, or irrigation levels) and geographical origin (Pepi et al, 2016).…”

Chemical elements as fingerprints of geographical origin in cultivars of Vitis vinifera L. raised on the same SO4 rootstock

“…Moreover, SO4, 110R, and 420A rootstocks may affect the content in anthocyanins, nitrogen distribution, and major and trace elements in grape (Hostetler et al 2007; Lee and Steenwerth 2011;Merli et al 2016). The amount of these compounds and of major and trace elements provide valuable information to evaluate the grape quality and the management practices (Lee and Steenwerth 2011;Pepi et al 2016a). Several studies focused on the relationship between grapes and soil composition for tracing geographical origin (Oddone et al 2009;Di Paola-Naranjo et al 2011;Aceto et al 2013;Cugnetto et al 2014;Mercurio et al 2014;Petrini et al 2015), while others examined the translocation and bioaccumulation of chemical elements in the soil-plant system (Angelova et al 1999;Amoros et al 2011Amoros et al , 2013Alagić et al 2015;Vystavna et al 2015;Pepi et al 2016b).…”

“…Recent studies dealt with geochemical characterization of grape berries grown under different soil management (Pepi et al 2016a). However, few studies concerned the relationship among rootstock, soil, and bedrock in grapevines.…”

Understanding the Quality of Local Vineyard Soils in Distinct Viticultural Areas: A Case Study in Alcubillas (La Mancha, Central Spain)

“…The fact that the type of soil influences the quality of the wine has been addressed by Renouf et al [9], who mapped the soils of seven of the most prestigious farms in the Bordeaux area in high resolution (between 1/1000 and 1/5000), covering 400 hectares of vineyards [4,42,43].…”
