Special Issue Information

Dear Colleagues,

This Special Issue on the “Fungal Metagenome of Tropical Soils” delves into the rich and diverse fungal communities found in tropical ecosystems. Fungi play essential roles in nutrient cycling, soil structure formation, and plant health in tropical soils, but much of their diversity and ecological functions remain unexplored. This Special Issue focuses on recent advances in metagenomics, which allow for the comprehensive study of fungal communities through high-throughput sequencing techniques. Key topics include the characterization of fungal biodiversity across different tropical biomes; the influence of environmental factors such as soil pH, organic matter content, and moisture levels on fungal community composition; and the interactions between soil fungi and plant roots. Additionally, this Special issue addresses how fungi contribute to ecosystem services like carbon sequestration, nutrient turnover, and pathogen suppression. This research is critical for improving sustainable land management, particularly in the face of deforestation, climate change, and agricultural expansion in tropical regions. The findings highlight the potential of fungal communities as bioindicators for soil health and as a resource for biotechnological applications. This Special Issue serves as a valuable resource for ecologists, microbiologists, and soil scientists interested in the complex roles of fungi in tropical ecosystems.

Potential topics include, but are not limited to, the following:

  • The characterization of fungal biodiversity across different tropical biomes;
  • The influence of environmental factors on fungal community composition;
  • The interactions between soil fungi and plant roots;
  • Future perspectives on the fungal metagenome.

This study evaluates the effectiveness of agroecological practices—organic fertilization and biofertilization—in enhancing ecosystem services in agroforestry and pasture systems. A field experiment was conducted over three years, comparing these practices to a control treatment and a natural ecosystem as a reference. Soil chemical, physical, and biological parameters were assessed, including soil organic carbon (SOC), microbial respiration, root density, and gene abundances of key microbial groups (Archaea, Bacteria, and Fungi). Organic fertilization resulted in a significant increase in SOC, phosphorus, microbial biomass, and root density, indicating improved soil structure and fertility. Biofertilization showed selective effects, promoting archaeal abundance but reducing bacterial and fungal diversity. Seasonal variation influenced nutrient cycling, with organic fertilization buffering against dry-season declines in microbial activity and nutrient availability. Aboveground dry biomass and litter deposition were highest in the natural ecosystem, followed by organic fertilization treatments in agroforestry and pasture systems. Despite improvements under agroecological management, the natural ecosystem consistently maintained superior soil quality and biological resilience. The findings highlight that organic inputs and diversified cropping systems enhance soil health but do not fully replicate the ecological benefits of undisturbed forests. In conclusion, agroecological practices provide viable alternatives to mitigate soil degradation and sustain ecosystem services in tropical Oxisols. Organic fertilization emerges as the most effective strategy, fostering long-term improvements in soil fertility and microbial dynamics. However, continued research is needed to optimize these practices for greater resilience and sustainability in Amazonian agroecosystems. Full article
