“…Soil Cd and Pb were significantly higher in Vineyard 1 than all other vineyards despite being a rural, agricultural area located away from local pollution sources. However, Cd and Pb in the soil can be inherited from the grey shale present (e.g., see trace elements in carbonates such as Protano and Rossi [ 25 ] or grey shales in Richardson et al [ 32 ]. Vineyard 5 had comparable As concentrations and Vineyards 3 and 4, but had significantly higher Pb and lower Cd than Vineyards 3 and 4.…”

“…Vineyard 5 had comparable As concentrations and Vineyards 3 and 4, but had significantly higher Pb and lower Cd than Vineyards 3 and 4. The higher Pb is likely due to recent long-range transport and deposition or addition, as Pb should be depleted from the extensive weathering [ 32 ], as observed with the lower Cd and Cu concentrations in Vineyard 5.…”

Wine is a popular beverage and may be a source of nutrient and toxic elements during human consumption. Here, we explored the variation in nutrient and toxic elements from soils to grape berries and commercial white wines (Chardonnay) at five USA vineyards (New York, Vermont, California, Virginia) with strongly contrasting geology, soils, and climates. Samples were analyzed for macronutrients (Ca, K, and Mg), micronutrients (Mn, Cu, and Zn), and toxic elements (As, Cd, and Pb). Our study showed contrasting macronutrient, micronutrient, and toxic element concentrations in soils and in vines, leaves, and grapes. However, plant tissue concentrations did not correspond with total soil concentrations, suggesting a disconnect governing their accumulation. Bioconcentration factors for soil to grape berry transfer suggest the accumulation of Ca, K and Mg in berries while Fe, Mn, Cu, Zn, and Pb were generally not accumulated in our study or in previous studies. Wines from the five vineyards studied had comparable nutrient, micronutrient, and toxic metal concentrations as wines from Germany, Italy, Portugal, Spain, Croatia, Czech Republic, and Japan. The transfer of nutrients and toxic elements from grape berries to wine indicated that only Ca, K, and Mg were added or retained while concentrations of all other micronutrients and toxic elements were somewhat to extensively diminished. Thus, there appears to be a substantial effect on the geochemistry of the wine from the grape from either the fermentation process (i.e., flocculation), or a dilution effect. We conclude that soils, geology, and climate do not appear to generate a unique geochemical terroir as the transfer and concentration of inorganic nutrients appear to be comparable across strongly contrasting vineyards. This has several implications for human health. Nutrients in wine have potential impacts for human nutrition, as wine can meet or exceed the recommended dietary requirements of Ca, K, Mg, and Fe, and toxic metals As and Pb concentrations were also non-trivial.

“…Exchangeable element fraction was measured by ammonium chloride extraction, and total elemental concentrations were determined by hydrofluoric‐nitric acid (HF‐HNO 3 ) strong acid digestion in Teflon vials following methodology from Richardson et al. (2022). Mineralogical characterization of the shale samples was performed by X‐ray diffraction on random powder mounts and orientated mounts for in‐depth clay mineral identification.…”

“…OM content of the soils was determined by loss on ignition (LOI) where 5 g of soil were weighed into crucibles and combusted in a muffle furnace at 550˚C for around 8 h. Samples were analyzed for soil particle size distribution using sedimentation columns and Bouyoucos hydrometer method (Mwendwa, 2022). Exchangeable element fraction was measured by ammonium chloride extraction, and total elemental concentrations were determined by hydrofluoricnitric acid (HF-HNO 3 ) strong acid digestion in Teflon vials following methodology from Richardson et al (2022).

As northeastern forests experience increased temperatures and fluctuations in precipitation patterns, montane soils will lose forest floor (Oi, Oe, Oa horizons) formation and their associated ecosystem services. Here, we conducted comparative laboratory soil column experiments to examine the effects of forest floor on sourcing and weathering of macroelements (Al, Si), macronutrients (Ca, Mg, P), and micronutrients (Cu and Zn) from two contrasting soils: a supraglacial‐till Inceptisol (Mt. Moosilauke, New Hampshire) and colluvium Ultisol (Lesesne State Forest, Virginia). Forest floor addition caused a significant increase in leaching of Ca, Mg, and Mn in the two soils. The forest floor only control leachate indicates the two mineral soils were net accumulators of Al, Si, P, Cu, Zn from the forest floor. Using Kd values, leachate Ca and Mg could be sourced directly from the forest floor traversing the soil column. We aimed to assess the biotic influence on element release from soil using a Na azide treatment to suppress microbial activities. Under Na azide treatments, Al, Ca, Mg, Mn, and Cu leachate decreased significantly for both soils but Na azide also did not affect or increased leachate Si, P, Cu, and Zn for the Lesesne soil. We attribute the effects from Na azide to changes in pH, dissolved organic carbon, and oxidation‐reduction potential as opposed to suppression of microbes. Thus, our results suggest that the loss of the forest floor will reduce storage of nutrients in the mineral soil, even across varying parent materials.This article is protected by copyright.
