Soil acidification, nutrient depletion, and hydrocarbon levels are all impacted by petroleum contamination, which is known to alter physico-chemical properties. Low-cost and sustainable remediation methods are necessary to restore soil functionality, especially in regions affected by oil contamination. Over the course of a 56-day incubation period, this study investigated the effectiveness of applying sawdust and poultry manure at different rates to clean up petroleum-contaminated soil. Regular measurements were made of soil nitrogen, pH, phosphorus, and total petroleum hydrocarbon (TPH). The effects of therapy, time, and their interaction on the collected data were evaluated using two-way analysis of variance (ANOVA). At each sampling interval, a one-way ANOVA with post-hoc mean separation (p < 0.05) was used, and Pearson correlation was used to detect temporal trends. The results show that petroleum contamination significantly reduced soil nutritional status and raised TPH levels while lowering soil pH. Organic amendments improved all soil properties (p < 0.05), with poultry manure-treated soils continuously out-performing sawdust-treated soils. TPH levels and remediation time showed significant negative connections (r=-0.95 to -0.97, p < 0.01), whereas nitrogen, phosphorus, and pH showed strong positive relationships with time (r=0.095 to 0.99, p < 0.01). Significant treatment*time interactions showed that remedial effectiveness gradually increased over time. In conclusion, manure-base remediation is a very effective and cost-effective way to reduce petroleum hydrocarbons while simultaneously restoring soil fertility and chemical equilibrium. Organic additions aid in the sustainable management of petroleum-contaminated soils, according to statistical data.
