Looks like you’ve clipped this slide to already. Litter decomposition plays a vital part in the nutrient budget of a forest ecosystem, where flora is influenced most significantly by nutrient recycling from plant litter (Vesterdal 1999; Wedderburn and Carter 1999).Litter decomposition encompasses ample breakdown of organic matter into CO 2 and nutrients via physical, biological and chemical pathways (Aerts 1997).
