  • The project examines the relationship between soil microorganisms and plants, noting that symbiotic microorganisms are essential for maintaining agriculture and food security. The research specifically tests whether managing arbuscular mycorrhizal fungi (AMF) can increase ecosystem resilience and soil carbon sinks.
  • Contrary to expectations that subsurface fungal biodiversity reacts slowly to environmental changes, DNA analysis of dominant AMF taxa reveals shifts in species abundance that occur even between seasons.
  • Seasonal changes, specifically during the warm and dry season, lead to a decline in both the diversity and symbiotic capacity of AMF, which can result in the loss of the symbiotic relationship between the fungi and the host plant. This suggests that climate change may negatively impact the subsurface and reduce the yield of associated plants.
  • In the páramos region, researchers from Bolivia and Ecuador have used this scientific knowledge to develop biofertilizers that increase potato growth, with experiments currently underway for other crops.
