Summary: Mercury, a persistent environmental pollutant, originates from anthropic activities such as fuel fossil emissions and industrial activities. In a study conducted in Central Brazil, it was found that road-traffic mercury emissions can lead to high mercury concentrations in soil, especially near the roadsides, gradually decreasing with distance.

Summary: This study investigated four deep, well-developed soils along a basalt-sandstone transition, revealing the influence of soil parent material on their genesis, chemical and mineralogical composition. Basalt soils were characterized by high clay contents and specific mineral components, while the sandstone soil had lower clay content and different mineral composition. The different soil types along the toposequence exhibited varying fertility levels and unique characteristics, likely influenced by the formation of an interstratified clay mineral complex.

Summary: The cerrado biome in Brazil is strategically important for agriculture, energy production, and other activities. However, the intensive use of chemicals and other products has led to potentially toxic elements contaminating the soil. This study evaluates the presence of these elements in the Ariranha stream basin and finds contamination levels exceeding regulatory limits.

Summary: The modern approach to the creation of biological products to stimulate plant growth is based on the study of specific inter-bacterial interactions. This study found that the introduction of strains of the genus Pseudomonas has a positive impact on the germination, growth, and development of leguminous plants, as well as the indigenous microbial community.

Summary: This study evaluated the presence and characteristics of nodulating bacteria in symbiosis with Mimosa spp. and identified Paraburkholderia sp. as the main bacteria present in the nodules. These bacteria effectively nodulated M. pudica but produced ineffective nodules in common bean. The results suggest that this symbiotic relationship may play a role in restoring ultramafic soils degraded by mining activity in Barro Alto areas.

Summary: This article examines the common red and yellow soils in the tropics, known as Ferralsols, which have high physical fertility due to their deeply weathered nature and strong microgranular structure of debated origin. The study finds evidence of the biological origin of the structure through the activity of social insects, including the presence of long-term termite activity markers such as 2:1 clays. This highlights the threat to the physical fertility of these soils and the broader impact on the water cycle in tropical regions if intensive agriculture reduces soil fauna biodiversity.

Summary: This study investigates the effects of root surface charge on manganese ion absorption and accumulation. It was found that legume plants have more negative charges and functional groups on their roots, allowing for better adsorption and accumulation of manganese ions. Additionally, coexisting calcium and magnesium ions are more effective in reducing manganese ion uptake and accumulation.

Summary: This study aimed to determine the concentration of potentially toxic elements (PTEs) and rare earth elements (REEs) in sandy soils under the Cerrado in Brazil, finding that soils from the Parnaiba Basin have higher concentrations of PTEs compared to soils from the Sao Francisco Basin. Geochemical correlations were observed between different elements and soil attributes in each basin, with Al2O3 being significant in the V and Cr geochemistry in the Parnaiba Basin. Unlike soils from the Parnaiba Basin, REEs do not correlate with the studied soil attributes in soils from the Sao Francisco Basin except for Ho and Lu, which showed negative associations with iron oxides.

Summary: The objective of this study was to enhance understanding of soil organic matter (SOM) stability in the Brazilian Cerrado by investigating soil properties and the interactions of biotic, climatic, and edaphic factors at the ecosystem scale. Three soil profiles in the same geomorphological unit with different total organic carbon (TOC) content were examined. The results showed that long-term carbon storage in Brazilian Cerrado soils was influenced by wildfires, bioturbation, and local edaphic controls on tree-grass composition. Soils with a thick A-horizon rich in organic matter had more trees, more charcoal, and higher levels of soil macrofauna activity.

Summary: The study investigated the changes in C and N fluxes during the decomposition of leguminous and non-leguminous leaf litters, and how these processes responded to different precipitation regimes. Results showed that d(13)C decreased in all litters, and d(15)N increased in leguminous litter while it decreased in non-leguminous litter. After 16 months, the fraction of litter derived N from leguminous litter was significantly higher than that of non-leguminous litter in the surface soil. C and N concentrations always had a positive correlation during decomposition, and increased precipitation enhanced their correlation.

Summary: The study evaluated the impact of converting leguminous Acacia mangium to non-leguminous Eucalyptus pellita on N2O emissions, and found that the conversion did not significantly reduce N2O emissions. This was mainly due to the lower nitrogen requirement of Eucalyptus compared to Acacia, resulting in higher soil NO3 content in Eucalyptus stands.

Summary: Efficient use of soil resources, such as nitrogen and phosphorus, can enhance plant resistance and resilience against drought in arid and semi-arid lands. Intercropping legume and non-legumes can improve phosphorus mineralization uptake and plant nutrient status. However, it is still unclear how intercropping systems using desert plant species impact soil-plant phosphorus fractions and their effects on nitrogen and water uptake capacity. This study investigated the impact of intercropping Alhagi sparsifolia and Karelinia caspia on soil-plant phosphorus fractions and soil-plant nutrients. The results suggested that intercropping improved microbe nitrogen-use efficiency, but had limited effects on phosphorus-use efficiency.

Summary: This study evaluated the physiological damage to soybean leaves under different Fe levels when exposed to non-waterlogged and waterlogged soils. The results showed that soil waterlogging caused significant damage to soybean plants, especially at higher Fe levels. However, when water availability was optimal, the damage caused by excess Fe was minimal.

Summary: This study evaluated the effects of copper (Cu) and iron (Fe) trace elements on nitrogen metabolism and biomass production in Leucaena leucocephala. It was found that the biomass production was higher in plants exposed to excess Fe than Cu, but the biomass gain was higher in Cu-exposed plants, especially in the roots. The tolerance and biomass production of L. leucocephala are related to the regulation of nitrogen metabolism and production of secondary metabolites.

Summary: Soil contamination by toxic elements negatively affects biodiversity, and boron is a micronutrient for plants. This study focused on the anatomical alterations in leaves and roots of Calopogonium mucunoides under high concentrations of boron in the soil. Anatomical changes were observed in the leaves and roots, and starch grains were detected in the parenchyma, indicating cell wall protection. The results provide an anatomical basis for potential phytoremediation processes.

Summary: Nickel (Ni) is a crucial metal that is more known for its toxicity than its role as a fertilizer. This study aimed to evaluate the development and physiological behavior of cotton plants under increasing Ni concentrations. The results showed that both seedlings and adult plants exhibited growth reduction and disturbances in seed reserves at higher Ni concentrations. The cotton plant demonstrated some defense strategies against Ni excess, but overall, it was not tolerant to Ni.

Summary: The study shows that inoculation with Bacillus subtilis can increase plant yield, gas exchange, and nutrient absorption in lettuce plants. The concentration of B. subtilis at 15.6 x 10(3) CFU/mL and 31.2 x 10(3) CFU/mL significantly increased plant yield and improved net photosynthesis rate, CO2 concentration, and water use efficiency. Inoculation with B. subtilis at lower concentrations also enhanced the absorption of calcium, magnesium, and sulfur by the plants.
