Abstract:The influence of inoculating earthworm (Pheretima Pingi. ) on phosphorus availability in red soil was studied by conducting pot experiments. Various aspects including decomposition of organic materials (rice straw, peanut residue and rape residue), soil total phosphorus and available phosphorus, soil carbohydrate content and soil phosphatase activity were taken into account. In this paper, the effect and mechanism of increasing phosphorus availability in red soil due to the inoculation of earthwormwere m...
