“…This is because cytosolic CuZn-SOD and mitochondrial Mn-SOD activities increase under conditions of Mn-excess as well as Mn-starvation [58,59]. The main factor determining P and Mn availability and solubility to plants is soil pH and P inactivation may occur also in calcareous soils due to high concentration of Ca ions and high soil pH [60]. Our results confirm this notion since P contents in the blade samples were below the nutritional optimum but did not reach deficiency levels.…”

Effects of Rootstocks on Blade Nutritional Content of Two Minority Grapevine Varieties Cultivated under Hyper-Arid Conditions in Northern Chile

In the 90s, as in other countries, transformation of Chilean viticulture brought about the introduction and spread of European grapevine varieties which has resulted in a massive loss of minor local and autochthonous grapevine varieties traditionally grown in several wine growing regions. Fortunately, in recent years, autochthonous and minority varieties have been revalued due to their high tolerance to pests and diseases and because of their adaptation to thermal and water stress triggered by global warming. In this study, we assessed the nutritional status of two autochthonous grapevines grafted onto four different rootstocks under the hyper-arid climatic conditions of Northern Chile over three consecutive seasons. The results showed that R32 rootstock induced high N, P, Ca, Mg and Mn levels in blades compared to Harmony rootstock. R32 rootstock and to a lesser extent, 1103 Paulsen and 140 Ruggeri rootstocks kept balanced levels of nutrients in blades collected from Moscatel Amarilla and Moscatel Negra grapevine varieties. Additionally, Harmony presented slight nutritional imbalance compared to the rest of studied rootstocks due to its low absorption of Mg, Mn, Ca and P, and its high K absorption, which was exacerbated under warm weather and salinity soil conditions. These results may provide a basis for specific cultivar/rootstock/site combinations, a nutritional guide for the viticulturists of Northern Chile, and options to diversify their production favoring the use of minority and autochthonous varieties that adapt well to hyper-arid conditions of Northern Chile.

“…Furthermore, there is an inherent competition between Fe 2+ and Mn 2+ regarding uptake in plants, and in conditions where iron is present in high amounts, the redox potential of the soil can be altered, promoting the oxidation of Mn 2+ to Mn 3+ or Mn 4+ , forms that are less soluble and hence less available to plants (Caballero et al, 2009;Moraghan & Freeman, 1978;Slunjski et al, 2010). In contrast, Fe de ciency is a more commonly observed problem in compost based growing media (Caballero et al, 2007;Smith et al, 2004;Wik et al, 2006), but this was not the issue in this study due to the exceptionally high content of Fe.…”

Aims Container-grown crops need reliable growing media that provide optimal conditions for plant growth. The traditional media peat and coconut coir are increasingly being replaced with sustainable alternatives. However, the availability of essential nutrients, such as manganese (Mn), in compost-based media remains a concern. This study therefore aimed to investigate Mn deficiencies in tomato seedlings grown in a compost consisting of 30% v/v sewage digestate and 70% v/v garden waste. Methods Tomato plants were cultivated from seeds under nursery conditions for eight weeks. The physical and chemical properties of the growing media, including bulk density, total pore space, air content, water retention, pH, electrical conductivity (EC), and essential nutrients, were assessed. Plant growth parameters such as height, leaf number, chlorophyll content, and fresh/dry weight were measured, alongside nutrient analysis. Results Despite the high Mn content in the compost, the tomato plants exhibited significant Mn deficiency. Factors contributing to this deficiency included high pH, abundant organic matter, and elevated iron and calcium levels, which likely formed insoluble compounds, reducing Mn availability. Additionally, the compost's low water retention and structural changes limited plant growth. Conclusions The findings emphasize the need to consider Mn availability in compost with a sewage-based component. This study highlights the complexities of nutrient availability in sustainable growing media and the importance of optimizing compost composition to support healthy plant growth.

“…Concerning heavy metals, Mn, Fe, Cu, Zn and Pb were determined. The presence of manganese, in oenological products, is directly linked to the capacity of the vine to absorb this element from the soil; consequently, its concentration can be extremely variable depending on the type of the vineyard soil (Slunjski et al, 2012;OIV, 2018). Mn concentration, determined in the BVG samples, ranged from 0.5 to 2.6 mg/kg.…”

The present study reports the chemical characterization of commercial balsamic vinegar glaze (BVG), a side product of the world-famous Aceto Balsamico di Modena (ABM). BVG, originally a homemade sweet and sour sauce, is now produced on an industrial scale and is gaining a growing success. The determination of total titratable acidity, dry matter, ash, metals, sugars, phenolic acids and furfurals is reported for BVG samples of different batches and years of production. Principal component analysis (PCA) and ANOVA test were applied to evaluate the experimental data. The results showed that the chemical characteristics of the product are almost unchanged in the investigated years and well reflect the characteristics of the ABM. Moreover, it was found that potentially harmful species, namely furfural compounds and heavy metals, were at a lower concentration than that of homologous products. In particular, the concentration of heavy metals, such as Cu, Zn and Pb, suggests that a preventive demetallization of the BVG starting raw materials occurs.
