A large number of total bacteria, fungi, actinomycetes, diazotrophs, Azotobacter and phosphobacteria were present in a black soil of calcareous nature during summer and cropping periods. They were higher in summer season even though the soil was totally dry with a moisture content of only 6.3 per cent. During the cropping period a higher population of fungi and actinomycetes were observed. The calcareous soils have pH values ranging from 8.1 to 8.7. Sorghum roots collected from five locations harboured Azospirillum and A. brasilense was predominant in Aruppukottai and Kovilpatti soil and A. lipoferum in Madurai, Kamudhi and Pudhur. They also exhibited VAM infection.
