The invention relates to the technical field of agriculture, and discloses a microorganism-mineral based composite material as well as a preparation method and application thereof. The microorganism-mineral-based composite material comprises the following components: iron phosphate powder and dissimilatory iron reduction microorganisms, wherein the dissimilatory iron reducing microorganisms comprise at least one of shewanella, geobacter, desulfurization vibrio, clostridium butyricum, geoacidophilus and iron-rich bacteria. The microorganism-mineral-based composite material provided by the invention comprises the mineral component iron phosphate and dissimilatory iron reduction microorganisms, and the dissimilatory iron reduction microorganisms can actively reduce the iron phosphate which is originally stable in chemical property and insoluble into Fe (II) with relatively high solubility, so that the crystal structure of the iron phosphate is destroyed; the phosphate fertilizer can release free PO4 < 3-> which can be absorbed and utilized by plants, the effect of the mineral reduction dissolution process driven by microorganisms is far better than that of simple addition when minerals or microorganisms are independently used, and an efficient phosphorus activation mechanism is formed.
