Abstract
Effects of Oil Spillage on Soil Fertility in Oleh and Irri Communities of Delta State
Author(s): Erhuen Ejomafuvwe*, Ali Peace Onya and Collins Ugochukwu IbejiThis research work was done to determine the effects of crude oil spillage on soil nutrients. It was done by analyzing some essential parameters found in the soil to determine the rate of loss or loss values of these nutrients in the soil. These parameters are pH, Total Microbial Population, Nitrogen, Phosphorus, Potassium, Sodium and Calcium. Soil samples were collected from Oleh/Irri communities in Isoko South of Delta State and were analyzed. Data obtained from the studied contaminated soil was treated and compared to the control soil samples. From the results obtained, the following were significantly reduced; pH concentration of the polluted soil from 6.20 to 5.32, Total microbial population variation was from 3.3x105 to 1.9x105 cfu/g, Nitrogen from 900 to 300 mg/kg, calcium from 172.5 to 77.5mg/kg, potassium from 857.5 to 686.3 mg/kg and sodium from 267.5 to 215mg/kg, but phosphorus from 5.00 to 5.33 mg/kg. The obtained data was subjected to statistical analysis using the Chi Square method at 5% level of significant and results showed that there is a significant effect of crude oil spillage on soil nutrients.
