The study was aimed to investigate the quality of soil polluted with dye effluents in Sokoto. Soil samples were collected from different dying centers in Sokoto in order to determine microbiological and physicochemical changes of soil using standard procedures. The results revealed the average count of viable bacteria in sampling sites that range from (1.05 x 106cfu/g – 1.5 x 105cfu/g) compared to that in control site (5.1 x 105cfu/g) while the fungi were (2.0 x 104 –5 x 104 cfu/g). The results showed that the soil sample contained different genera of microorganisms which include: Bacillus cereus, Bacilli subtilis, Clostridium absonum, Clostridium perfringens, Streptococcus pyogenes, Aspergillus niger, Aspergillus flavus, Alternaria, Sporotrichum, Cladosporium, Curvularia, as well as Geotrichum. Similarly, the physicochemical analysis of soil revealed high levels of pH (11.1-11.5) in all the sampling sites which exceeded the tolerable levels, while Temperature (29.5oC) Magnesium (66 – 10 mg/kg), Potassium (339 - 440.7 mg/kg), Sodium (98.9-259.9 mg/kg), Calcium (120 – 320 mg/kg), Organic matter (0.58 – 1.96%), Nitrogen (0.05 – 0.09%), and Phosphorus (0.73 – 1.05 mg/ml) Cation exchange capacity (5.68 – 7.04 cmol/kg) in all the sampling sites. Some these levels fall within the permissible levels set by the Federal Ministry of Environment while others are not. The presence of the microorganisms and chemical substances at low levels indicate that there is no much potential threat pose to the inhabitants of the areas.
