Earthworms offset strawinduced increase of greenhouse gas. We hypothesized that 1 earthworm can increase the co 2 and n 2 o emissions, and the interactions between earthworms and mesofauna would make the effects more obvious, 2 the addition of predatory mites can enhance soil co 2 and n 2 o emissions in longterm conservation tillage systems.
