“…Among these soil factors, it is necessary to highlight those related to soil characteristics (e.g., effective depth, stoniness, erosion risk associated with the slope, organic matter content, N and P contents, C/N ratio, effective cation exchange capacity, macronutrient (K, Mg, Ca) balance, pH, and/or salinity) [28,30]. Moreover, total metal contents, particularly Cu and Zn, are used as indicators to assess vineyard soil pollution associated with fungicides [4,31,32]. In any case, the total metal content is not usually a good indicator to assess pollution in vineyard soils.…”
