“…On the other hand, low pH makes cationic micronutrients such as Cu and Mn more available for absorption by the plant and accumulation in the shoots and roots. It is widely known that cationic micronutrient availability in tropical soils increases with decreasing pH (Van Eynde et al 2022). Under very acidic conditions, there is considerable solubilization of Al from the soil, which becomes a potential acidity component and, consequently, as a phytotoxic element, one of the factors responsible for the unfavorable effects of acidity on plants (Yerima et al 2020).…”

Amazonian reforestation programs emphasize the use of species native to the region. However, reforestation using native species requires the production of high-quality seedlings. The present study aimed to evaluate the development and quality of seedlings of paricá (Schizolobium parahyba var. amazonicum), a species native to the Amazon with high potential for reforestation activities. We carried out a greenhouse experiment in which seedlings were subjected to treatments with varying presence of major and micronutrients in the substrate, and evaluated the effect on functional attributes (plant height, stem diameter, specific leaf area, shoot and root dry matter) and physiological response (chlorophyll a, b and carotenoid concentrations). Our results showed that nutrient omission significantly affects paricá seedling growth. Considering the assessed biometric and physiological variables, the highest nutritional requirements of seedlings were for N, P, K, micronutrients, Mg and S, while seedling quality was maintained in the absence of Ca. Overall, this species shows efficient use of available nutrients and potential for growth in soils with low concentrations of bases. Therefore, for the production of high-quality paricá seedlings, major and micronutrients should be added and lime is essential, but the good seedling performance under Ca omission suggested that this element does not need to be added to the soil.

The charging behavior of biochars resulting from (de)protonation is important for assessing their potential as adsorbents for in situ immobilization of trace metals in polluted soils. Here, the pH-charge curves of 20 newly produced biochars were measured, whereas curves of 16 other biochars were collected from literature. All 36 biochars were produced from different plantbased materials at various pyrolysis temperatures. The pH-charging data were used to derive proton binding parameters for a novel three-site NICA-Donnan model, accounting for proton binding to carboxylic (site a1 ) and phenolic (site a2 ) acidic groups as well as to a basic (site b ) group. This model successfully described the proton binding behavior of the 36 biochars at different ionic strengths for the first time, by extending the classical two-site NICA model with a basic group in combination with an electrostatic Donnan model using a fixed volume of 0.1 L kg −1 . A set of generic proton binding parameters derived from the data resulted in a relative error of ∼6% for proton adsorption by all 36 biochars. Recommended parameters are Q a1 = 0.39 mol kg −1 , log K ̃a1 = 4.55, m a1 = 0.70, Q a2 = 0.59 mol kg −1 , log K ̃a2 = 8.10, m a2 = 0.80, Q b = 0.39 mol kg −1 , log K ̃b = 4.78, and m b = 0.76.

“…Various parent materials and soil texture influence bacterial diversity and nutrients, particularly SOC [13]. Heavy metals, such as manganese (Mn), zinc (Zn), iron (Fe), and copper (Cu), are fundamental for crop production, yield quantity, and holding yield responses to frequent NPK fertilizer [14]. However, an increase of these elements in soil beyond the permissible limit can reduce crop yields and be poisonous [15].…”

Despite studies focusing on soil substrates (carbon and nitrogen) and heavy metal availability, the impact of diversified parent materials in arid alkaline regions has received little attention. To reveal the influence of parent material, we investigated four different parent materials: fluvio-marine, Nile alluvial, lacustrine, and aeolian deposits. We assessed the effect of soil parent materials through selected soil physical and chemical properties, such as clay content, bulk density, pH, and available phosphorus (AP). The Tukey HSD test (SPSS ver. 23) was used to assess the soils derived from these different sediments. Using the R “glmulti” package, we examined this effect in a model of mixed-effects meta-regression. The sum of Akaike weights for models that contained each element was used to estimate the importance of each factor. The average contents of soil organic carbon (SOC) and total N in alluvial deposits were greater (p < 0.001) than those of marine, aeolian, and lacustrine deposits. A multivariate analysis in arid regions revealed that parent material, soil pH, and the availability of P had the greatest effects on SOC concentration, whereas clay content, available P, soil pH, parent material, and bulk density had the greatest effects on soil total nitrogen. The average content of Fe in the aeolian deposits was greater (p < 0.001) than those of marine, alluvial, and lacustrine deposits, without any significant differences between the latter two deposits. We found that the highest average contents of zinc (Zn), manganese (Mn), and copper (Cu) were recorded in alluvial deposits, with significant differences between other deposits. Soil parent material was the major factor impacting soil iron (Fe) content, along with clay content and soil pH. However, soil bulk density was the most important factor controlling soil Zn and Mn contents, while SOC drove Cu content. This study will help in developing a more accurate model of the dynamics of soil substrates and availability of heavy metals by considering readily available variables, such as parent materials, soil pH, soil bulk density, and clay content.
