Abstract
The present study was carried out from Autumn (2012)to Summer (2013) to study the soil properties, quantitative and qualitative of bacterial diversity.Samples were collected from five sites in Babylon province /Middle of Iraq : landfill site of solid waste/Mahaweel; warehouse Morgan oil/ Hilla, central terminal bas station/Hilla, brick factories in Al-Kifil and agricultural area in the region of Thmazah /Hilla). Some physical and chemical properties of soil, were studied (temperature, pH, electrical conductivity, organic matter, cation exchange capacity, carbonat, bicarbonate, calcium, magnesium, total nitrogen, and soil texture).More the study was achieved to investigat the quality and quontity of divuisty bacterial divursity in soil the results showed a clear divergence in soil characteristics between study sites and seasons, electrical conductivity (2.3-143.00)µs/cm, pH (7.9 - 6.7), calcium (5.20-116.6) μg.L-1, magnesium (4.57-416.90) μg.L-1, carbonat recorded All reading as N.D, bicarbonate(1.00-36.90) μg.L-1. Organic matter(1.35-20.80) μg.gm-1.Thecation exchange capacity(10.98-23.03) μg.gm-1,The total Nitrogen(0.24-19.70) μg.gm-1. The results showed that the number of bacteria increased in the study sites and also increased in the agricultural soils compared with other types of soil, total count of bacteria were (297 × 106 - 6 × 106) CFU-1gm. The most dominant species of isolated bacteria were Bacillus.spp, E.coli , Salmonella.
