Evaluation of the ecosystem of agricultural soils in al-hira sub-district

Abstract

The results of the analyses indicate that the presence of Escherichia coli (E. coli) bacteria in all the locations of agricultural soils in Al-Hira sub-district indicates the presence of pollution due to human and animal wastes, which occurred through the use of wastewater to irrigate farmlands. They discovered that the highest rates of the E. coli bacteria occurred during spring and autumn seasons which are linked with good temperatures and humidity that supports the activity and reproduction process of the bacteria. On the other hand, minimum was recorded during winter and summer since the conditions of climatic conditions are not conducive to the growth of bacteria as they are harsh.
