Overview

Experimental investigation reveals altered soil microbiome health due to leached organic carbon in forests, suggesting climate implications.

Key Points

  • The research examines how enhanced leaf litter leaching affects the forest soil microbiome and biogeochemical processes.
  • Used homogenized soil columns subjected to artificial precipitation for 3 months.
  • Adjusted initial levels of leached dissolved organic carbon based on leaf litter flushing.
  • Measured hydrological and geochemical parameters continuously over time and depth.
  • Increased availability of carbon and nitrogen in porewater by four-fold and two-fold respectively.
  • Expansion of anoxic zones and reduced metabolic potential for cellulolysis and N2 fixation in unsaturated soils.
  • Decreased phylogenetic diversity and functional diversity of the soil microbiome.
