PROBLEM TO BE SOLVED: To provide light-weight artificial soil produced so as to prevent granular foam material from floating on a soil surface layer to be dispersed or flow out, enable greening material to sufficiently exert its performance, and also prevent plants from causing water rot or root rot: and to provide a method for producing light-weight artificial soil and a method for creating light-weight soil base using the artificial soil. SOLUTION: The light-weight artificial soil is obtained by fixedly attaching at least either one kind of greening material B selected from Kanuma soil, black soil, silicon soil, Akadama soil, coal ash, decomposed granite soil, reddish soil, volcanic ash, leaf soil, zeolite, clay, pearlite, peat moss and bark compost to the surface of granular foam material (A). The greening material B contains organic solvent comprising aromatic solvent or halogenated hydrocarbon solvent, and the greening material B fixedly attached to the surface of the granular foam material (A) presents such a formation that part of the greening material is buried under at least part of the material (A) dissolved by the organic solvent.
