| description | The invention provides a soil remediation and improvement method which comprises the following steps: regulating and controlling a crystalline phase of a mineralized product biological calcium carbonate induced by bacillus pasteurii by using a biological surfactant, so that calcite is converted into vaterite. Preparing a biochar/magnesium ammonium phosphate composite material from the filtrate obtained after the biological calcium carbonate is prepared, the biochar activated by phosphoric acid, magnesium oxide and the like, and then sequentially applying the biological calcium carbonate and the biochar/magnesium ammonium phosphate composite material to the surrounding soil, polluted by harmful metal elements, of the mining area. The method is simple in process, low in cost and free of secondary pollution, and has the effects of repairing and improving the soil around the heavy metal/rare earth element polluted mining area.
