The study was undertaken to evaluate the soil quality of post flood soils of Agro- ecological unit 4 in Pathanamthitta district of Kerala. Representative surface soil samples were collected from this area after the occurrence of flood. The collected soil samples were laboratory analyzed for different physical, chemical and biological properties. Principal component analysis method was used for selection of minimum data set which influenced the soil quality of this area. By scoring and weighted additive method, soil quality index was calculated and soils were grouped into low, medium and good category according to relative soil quality index. Medium soil quality was observed for 76 per cent of samples and good for 24 per cent.
