In order to investigate the applicability of coal fly ash granular materials (FAGM) as a vegetation medium, a grass cultivation experiment was performed. Five type of soil sample were prepared with different combination of FAGM and improved materials made with sediment of reservoir. Both of fly ash and sediment of reservoir are waste product. A weathered granite soil which is used for reclamation very popularly was also used as a control. The results were evaluated with a vegetation fraction and NDVI (Normalized Difference Vegetation Index), which estimate vegetation vitality with spectral characteristics. Pure FAGM didn't show enough applicability, but mixed sample (FAGM : sediment=50:50〜75:25) showed good applicability as a material for plant growing medium.
