Analysis of litter input types reveals varying impacts on soil carbon dynamics across forest ecosystems along a climate gradient.

Key Points

This research investigates how different types of litter input affect soil organic carbon turnover and flow among various forest ecosystems along a climate gradient in China.
Examined soil aggregate mass and carbon content over 2 years of litter input.
Applied 13C isotope tracing to track carbon movement among soil aggregates.
Compared effects in tropical, temperate, and boreal forests.
Belowground root litter input significantly enhanced soil aggregation across all forest types.
Aboveground litter input had no significant impact on soil aggregation.
In the tropical forest, belowground litter increased litter-derived carbon and total carbon content but reduced native carbon content.
Minimal effects were observed in boreal and temperate forests regarding litter input on carbon contents.
