“…The B in leaves was found to be positively correlated to the soil pH and negatively correlated to soil Al 3+ and m%, which can be explained by the direct effect that the soil pH has on Al 3+ availability and consequently on the m%, although the availability of Al 3+ is also influenced by mineralogy and soil organic carbon (RABEL et al, 2018). Additionally, these correlations explained the high variation in the concentration of Mn in yerba mate leaves.…”

Yerba mate (Ilex paraguariensis St. Hil.) is a raw material used in making a beverage whose chemical composition can be altered by the growing environment and the management adopted during its cultivation. Thus, it is essential that scientific studies are undertaken to understand the chemical composition of yerba mate related to its growing environment. The aim of this work was to determine the elemental composition in the leaves of yerba mate from native cultivations that had never received fertilization and liming, from the Southern Region of the state of Paraná, Brazil. Soil and leaf samples were collected at 11 sites located in the municipalities of São Mateus do Sul, Mallet, São João do Triunfo, and Lapa. Leaf analyzes were performed in an Optical Emission Spectrometer with Inductively Coupled Plasma. The mean concentrations observed (mg kg -1 ), in decreasing order, were: Ca -7880; K -7310; Mn -2418; -Mg -820; P -720; Al -474; Fe -231; B -78; Zn -62; Ba -62; Cu -8.9; Ni -5.6; Cr -0.82; V -0.53; Co -0.17. The Mn concentrations were directly correlated with Al 3+ saturation and inversely correlated with base saturation, pH, and the available Ca 2+ , demonstrating that changes among these soil components can significantly modify the Mn concentrations in the yerba mate leaves. The high concentrations of Mn and Al in the leaves of yerba mate demonstrate the adaptation of this species to acidic soils with high saturation of Al 3+ . Keywords: Ilex paraguariensis, trace elements, mineral nutrition, soil fertility. Resumo Influência das propriedades químicas do solo na composição elementar das folhas de erva-mate.A ervamate (Ilex paraguariensis St. Hil.) é matéria prima de bebidas cuja composição química pode vir a ser alterada de acordo com o ambiente de cultivo e manejo adotados, tornando-se fundamental trabalhos que discutam a composição química de suas folhas. O objetivo deste trabalho foi determinar a composição elementar de folhas de erva-mate de ervais nativos, que nunca receberam adubação e calagem na região Sul do estado do Paraná. Amostras de solo e folhas de erva-mate in natura foram coletadas em 11 propriedades nos municípios de São Mateus do Sul, Mallet, São João do Triunfo e Lapa. As análises das folhas foram efetuadas em ICP-OES. As concentrações médias observadas em ordem decrescentes em mg kg -1 foram: Ca -7880; K -7310; Mn -2418; -Mg -820; P -720; Al -474; Fe -231; B -78; Zn -62; Ba 62; Cu -8,9; Ni -5,6; Cr -0,82; V -0,53; Co -0,17. Os teores de Mn mostraram-se diretamente correlacionado com a saturação por Al 3+ e inversamente correlacionado com a saturação por base, pH e Ca 2+ disponível no solo, demonstrando que alterações entre estes componentes do solo pode modificar significativamente os teores de Mn nas folhas de erva-mate. Os elevados teores de Mn e Al nas folhas de erva-mate demonstram a adaptação desta espécie para solos ácidos e com elevada saturação por Al 3+ . Palavra-chave: Ilex paraguarienses, elementos-traço, nutrição mineral, fertilidade do solo.

“…Araucaria angustifolia seed are primarily harvested from trees under native conditions in subtropical Brazil (extractivism) since there are few planted forests. In the region of occurrence, there are distinct environmental growth conditions (Alvares et al 2013;Rabel et al 2018). However, there is a lack of information regarding the nutritional composition of A. angustifolia seeds since past studies have only investigated isolated samples (Cordenunsi et al 2004;Schveitzer et al 2014).…”

“…These results can be considered promising, considering three main points:( i) there have been reports of soil Pb contamination in Paraná (Brazil) (Barbosa et al., 2020; Piedade et al., 2014); (ii) in general, soils in Paraná state are very acid (Rabel et al., 2018); and (iii) due to the high production of Limed sewage sludge in Paraná state (Bittencourt et al., 2016; Poggere et al., 2012). Considering the reduction of more bioavailable Pb fractions occurred regardless of the soil mineralogy (Figure 5), the application of limed sewage sludge can be probably efficient for Pb remediation in other places that produce this type of sewage sludge, such as Canada, Ireland, South Africa, Turkey, and the United States (Healy et al., 2016; LeBlanc et al., 2008).…”

Little attention has been paid to the effects of soil mineralogy on remediation efficiency of sewage sludge. To fill this gap, we applied limed sewage sludge to Pb‐contaminated soil samples of an Oxisol rich in hematite (309 g kg−1) and gibbsite (322 g kg−1) and to an Inceptisol rich in kaolinite (683 g kg−1). Soil samples were collected from B horizon, being both of them acid, clayey, and poor in organic matter. Soil samples were incubated for 40 days and evaluated for Pb after fractioning. Limed sewage sludge neutralized the soluble and exchangeable‐Pb forms in the kaolinitic and oxidic soils primarily as a result of pH increase. It was measured increased concentrations of unavailable forms of Pb such as precipitated‐Pb, Fe and Mn oxide‐Pb, gibbsite and kaolinite‐Pb, and residual‐Pb in the kaolinitic Inceptisol. Likewise, it measured increased concentrations of precipitated‐Pb, organic matter‐Pb, Fe and Mn oxide‐Pb, and residual‐Pb in the Oxisol. Results have demonstrated that limed sewage sludge decreases concentrations of Pb fractions more susceptible to leaching or more bioavailable, while increasing Pb fractions that pose lower risks to the environment. Such results indicate that limed sewage sludge can be used for the remediation of Pb‐contaminated soils regardless of soil mineralogy.
