The invention discloses a multi-microelement mineral substance polymer for soil improvement and remediation. The polymer comprises remediation minerals, wherein the remediation minerals consist of silicon dioxide, aluminum oxide, iron sesquioxide, potassium oxide, sodium oxide, calcium oxide, magnesium oxide, manganese oxide, phosphorus oxide, germanium oxide, lead oxide, zinc oxide, chromic oxide, copper oxide, nickel oxide, cobaltous oxide, chromic oxide, arsenious oxide and cesium oxide. The multi-microelement mineral substance polymer for soil improvement and remediation, which is disclosed by the invention, consists of multiple mineral elements, the soil remediation principle of the polymer is that as the polymer contains multiple microelements, all microelements come from different minerals, due to addition of the mineral polymer into the soil, the microelements are replenished into the soil, then the fertilization of the soil is improved, the soil vitality is activated, the structure is balanced, and the purposes of improvement and remediation are achieved. Due to addition of multiple microelements, the polymer is remarkable and comprehensive in soil improvement and remediation effect.
