The present invention relates to a method for manufacturing a soil ameliorater containing a rare earth element and to a soil ameliorater obtained by the method, wherein the provided soil ameliorater is manufactured by additional mixing of water to a rare earth element mixture composed of rare earth element compounds, a chitosan liquid, a citric acid powder, concentrated minerals, rice bran, corn flour, zeolite, syrup and complex microorganisms, a culturing step and a drying step. As the soil ameliorater is mixed with soil contains a rare earth element compound, the chitosan liquid and the like, the nutrients including the components of the soil ameliorater are absorbed by the plants, so that the immunity can be improved from the insect pests against the growth of the plants, thereby maximizing the efficiency of plant insect-proof prevention and maximizing plant growth efficiency.(S110) Mixture preparation step of preparing a rare earth compound(S120) Additional mixing step of adding 40 parts by weight of water with respect to 100 parts by weight of the prepared rare earth mixture(S130) Culturing step of culturing the rare earth mixture to which the water is added for 48 hours under a specific temperature condition(S140) Drying step of drying an improving agent, having been cultured through the mixture preparation, the additional mixing and the culturing stepCOPYRIGHT KIPO 2019
