Feeding and defecation of earthworms alters phosphorus forms and resource allocation to enzyme production in an arable Andisol

Context Phosphorus cycles in the soil through chemical and biological reactions, and earthworms have been suggested to alter P distribution in soil. Aims We investigated the effects of earthworms’ feeding and defecation on soil phosphorus forms and the biochemical and physicochemical properties of the soil. Methods Earthworms were cultured in an Andisol, which is characterized by a high P adsorption capacity, with the addition of dried rice straw compost at three different levels. We evaluated P
