Summary: Biochar is a promising alternative for remediation of areas contaminated by mining waste, but its effectiveness in immobilizing cationic and anionic contaminants varies based on pyrolysis temperature. The application of biochar can change the availability of As and Pb in sediments, alter the chemical composition of carbon structures, and impact enzyme activity of microorganisms. The reduction in Pb availability and increase in pH after application of biochar at high temperatures suggests potential for reducing environmental risks associated with Pb contamination.

Summary: We analyzed RNA-sequencing samples to investigate the mechanisms behind differences in photosynthesis and sugar accumulation between Saccharum spontaneum and Saccharum officinarum. The divergences in sugar accumulation were found to be due to enrichment of carbohydrate metabolism and the pentose phosphate pathway. Compared to S. officinarum, S. spontaneum showed higher enrichment of photosynthesis and more complex regulation of photosynthesis-related genes, as well as a lack of gene interactions with sulfur assimilation stimulated by photorespiration.

Summary: Recently, the eastern region of Maranhao state in Northeastern Brazil has seen significant land-use change from native vegetation to soybean cultivation. However, this change has resulted in substantial depletion of soil organic carbon (SOC) and nitrogen due to soil characteristics. Two factors, different timeframes after land-use change and contrasting soil management practices, were quantified to assess these impacts. The results showed that SOC stocks decreased by 35% after 8 and 15 years of land-use change, with a decrease in labile carbon and microbial carbon between 20% and 60% during the same period. When comparing soil management practices, no-tillage did not significantly affect SOC stocks, but both labile carbon and microbial carbon decreased by 15% with no-tillage and by 40% with mouldboard plough. These findings highlight the importance of adopting best agricultural management practices to preserve and increase SOC, reducing greenhouse gas emissions and promoting sustainability and profitability.

Summary: Overexploitation of natural forest resources in the tropical semiarid region of Brazil leads to soil degradation, reduction in microbial and plant biomass, and loss of C and N from soils. This study found that degraded soils had significantly lower C and N stocks, abundance and activity of total bacteria and fungi, and decreased abundance of diazotrophic and phosphorus-mineralizing bacteria compared to preserved or partially degraded soils. However, the abundance of total bacteria and fungi genes and glomalin content remained unchanged. The alkaline phosphatase activity indicated that mineralizing microorganisms can still make phosphorus constantly available in soils without vegetation cover.

Summary: The expansion of agricultural areas worldwide due to growing demand for resources has led to poor soil management and soil physical degradation. This study investigated the effects of land conversion on soil physical properties in the Brazilian Cerrado region, including the conversion of native Cerrado vegetation to pasture and cropland. The results suggest that compaction processes equally reduced soil porosity in both pasture and cropland, but soil penetration resistance and stable mean weight diameter of soil aggregates were higher in pasture. The highest levels of organic carbon were observed in cropland, while the lowest levels occurred in pasture.

Summary: The expansion of sugarcane cultivation in areas currently occupied by low-productivity pastures has led to changes in soil structure and organic matter storage. This study investigated the impact of land-use change on soil organic matter fractions in two contrasting soil types and explored the correlations with soil aggregation and carbon stocks. The findings suggest that converting pasture to sugarcane can increase carbon stocks in clayey soils but decrease carbon stocks in sandy soils.

Summary: The production and export of fine table grapes in the Brazilian semi-arid tropical region is threatened by the increasing cost of phosphate fertilizers and leaching of phosphorus (P) that threatens local water bodies. This study quantified the organic and inorganic fractions of P and determined the chemical and microbiological attributes related to its mineralization. The results showed that the use of phosphate fertilizers increased P fractions and microbial activity. The higher Pmic and glomalin production in fertilized areas indicated positive effects on P-mineralized bacteria and arbuscular mycorrhizal fungi in the current agricultural system.

Summary: Adopting land-uses that contribute with a considerable litter input affects soil organic carbon accumulation and the physical fractions of soil organic matter. This study aimed to determine the impact of agroforestry systems on soil organic carbon content and physical fractions, as well as the influence of seasonality on the compartmentalization of soil organic matter. The results showed significant changes in soil organic carbon contents and physical fractions after a short period of implementing agroforestry systems, with the particulate fraction being particularly affected. The Carbon Management Index was found to be sensitive in detecting changes and revealed that the agroforestry system with the highest species density had the highest carbon accumulation in the soil.

Summary: Soil microbial community coalescence, the mixing and interaction of microbial communities, has been found to enhance the stability and complexity of rhizobacterial networks, leading to improved plant health and biomass. This study investigated the effects of different degrees of bacterial community coalescence on plant disease resistance by mixing soils from healthy and diseased habitats for watermelon planting. The results showed that mixing in more healthy soil reduced the plant disease index and increased biomass by improving the stability and complexity of the rhizobacterial network. Core taxa Nitrospirillum and Singulisphaera were enriched in the rhizosphere from healthy soils and played important roles in disease suppression and regulating the positive cohesion and modularity of the networks. Overall, these findings provide insights into the potential mechanism of microbial community coalescence for improving plant microbial community function and suggest new tools for enhancing plant fitness via soil microbiota mixing.

Summary: Collembolans, the diverse group of soil invertebrates, are affected by anthropogenic climate warming, which alters their diversity and density. In addition to abiotic stressors, changes in food availability, specifically the abundance of saprotrophic and mycorrhizal fungi, influence Collembola responses to climate warming. Collembolans prefer saprotrophic fungi but rely on mycorrhizal fungi when food sources are scarce. Understanding the mechanisms behind these dietary shifts in warm-dry and warm-wet soil conditions is crucial for predicting the impact of climate change on Collembola-fungal interactions.
