A study on “Effect of cement dust deposition on soil microbial properties” was conducted at Department of Environmental Sciences, Advanced Post Graduate Centre, Lam, Guntur during 2017-2018. A total of 160 soil samples were collected around cement industry in Satrasala village, near Macherla in Guntur district during the months of August (Before sowing of crop) and December (After harvest of crop) 2017 at various distances from cement industry viz., 250, 500, 1000, 2000 m and at the distance of 2250, 2500, 3000 and 4000 m away as check area. The results showed that the microbial population i.e., bacteria and fungi was influenced by the cement dust deposition. The minimum population of bacteria 27.1 and 26.9 x 105 CFU g-1 was recorded before sowing and after harvest of crop at 250 m and population increased to 87.1 and 89.1 x 105 CFU g-1 with increase in distance up to 2000 m distance from cement industry. Similar trend was observed in case of fungal population also. Minimum population of 10.4 and 9.3 x 103 CFU g-1 was recorded before sowing and after harvest of crop at 250 m from cement industry and population increased to 26.1 and 25.5 x 103 CFU g-1 with increase in distance up to 2000 m from cement industry.
