Field experiment investigates soil cation availability impacted by native and invasive earthworms, indicating ecological dynamics.
Earthworm invasion alters soil nutrient cycles. This study investigated the effects of the native earthworm , the invasive , and their co-occurrence on the availability of water-soluble cations NH , K, Na, Mg, and Ca. To achieve this, a simulated field experiment was conducted in soil mesocosms, and the cation content was measured by capillary electrophoresis. The experiment revealed that the invasive species only relatively weak altered cation availability within a single growing season. The impact of invasion depended on whether the soil was already inhabited by the native species or not. The effect of on cation availability was studied for the first time.
