The document examines the relationship between soil microorganisms and plants, focusing on arbuscular mycorrhizal fungi (AMF). It argues that land-use and climate changes affect these microorganisms, which in turn impacts plant nutrition and agricultural yields. Findings indicate that AMF diversity and symbiotic capacity can decline during warm and dry seasons, potentially leading to a loss of the symbiotic relationship. In the páramos region, this research has been applied to create biofertilizers that increase potato growth in Bolivia and Ecuador.

  • Land-use and land-cover changes impact the ecological functions of soil microorganisms, which subsequently alters their relationship with plants, affecting agriculture and food security.
  • DNA analysis of dominant arbuscular mycorrhizal fungi (AMF) taxa reveals that species abundance changes even between seasons, contradicting the expectation that subsurface fungal biodiversity reacts slowly to environmental changes.
  • Both the diversity and symbiotic capacity of AMF decrease during the warm and dry season, which may result in the total loss of the symbiotic relationship between the fungi and the host plant, potentially reducing plant yields due to climate change.
  • In the páramos region, research on soil microorganisms has been used to develop biofertilizers that enhance the growth of potatoes in Bolivia and Ecuador.
