Bacterial population, temperature and moisture content were determined from the surface and at a depth of 100 cm from the manure heaps. At 100 cm depth the survival of bacteria (mean count: 1670000) is somewhat higher than the exposed surface (mean count: 953500). At 100 cm depth the anaerobic bacteria and streptococcus faecalis persist longer than E. coli and shigella sp. The moisture content at the surface varied from (0.2-20%) while at 100 cm depth was (30-66%). The temperature recovered from manure heaps at 100 cm depth was between 30°C- 39°C and at the surface was from 15°C 20°C.
