PROBLEM TO BE SOLVED : To provide a method as a result of research and development in such a manner that mainly contaminated soil is efficiently and inexpensively cured and treated. SOLUTION : The bark, branches and leaves or drawn roots of Japanese cedars, Japanese cypresses, hiba arborvitaes or eucalyptus discharged as industrial waste and hard to be decayed or having decaying properties are made into material worked so as to be fibrous or powdery, and the material is utilized, e.g., for waste water in an eutrophication state with components such as an organic solvent, endocrine disrupter, heavy metals, rare metals, phosphorous, nitrogen and potassium. Alternatively, the material is blended with earth brought from another place and mixed in the soil, seed, compound fertilizer or the like, and the blend is applied to the surface and circumference of contaminated soil by spraying, scattering or the like. Alternatively, the same can be utilized in a state of being inserted between soils in the single use of the base material or in the combined use with the other inorganic or organic adsorbent.
