The invention discloses a composite agent of a farmland soil anti-hardening agent and a fertilizer and a using method thereof. The composite agent of the farmland soil anti-hardening agent and the fertilizer comprises a water-soluble polysaccharide, bone glue, a surfactant and a certain amount of a chemical fertilizer. The water-soluble polysaccharide is a structure of polyhydroxyl. The structure of polyhydroxyl in water solution of the water-soluble polysaccharide is a three-dimensional network structure. The water-soluble polysaccharide is dissolved in water, and sprayed in a farmland. The three-dimensional network structure is formed on the surface of soil and in a certain depth, and certain space is formed between soil particles, so aggregation of the soil is avoided. The bone glue material is used as a degradation adjusting agent for solving a problem of a degradation speed of the water-soluble polysaccharide in natural conditions. Because of the effect of the surfactant, inorganic micromolecules of the
