Abstract

Earthworms play an essential part in determining the greenhouse-gas balance of soils worldwide and their influence is expected to grow over the next decades. They are thought to stimulate carbon sequestration in soil aggregates but also to increase emissions of the main greenhouse gases carbon dioxide and nitrous oxide. Hence it remains highly controversial whether earthworms predominantly affect soils to act as a net source or sink of greenhouse gases. Here we provide a quantitative review of the overall effect of earthworms on the soil greenhouse-gas balance. Our results suggest that although earthworms are largely beneficial to soil fertility they increase net soil greenhouse-gas emissions.
