Remediation of Crankcase Oil Contaminated Soil with Different Sources of Manure in Abakaliki, Southeast, Nigeria

Nwite Jn¹,

Abstract: Remediation of crankcase oil contaminated soil with different sources of manure was studied using randomized complete block design with four treatments which were replicated five times. Oba super ∏ hybrid variety of maize was used as a test crop. Results showed significant (P<0.05) treatment effect on aggregate stability, gravimetric moisture content (GMC), available phosphorus, calcium and cation exchange capacity (CEC) as well as plant height and grain yield of maize relative to control. Significantly (P<0.0… Show more

Nigeria is facing the problem of soil degradation as a result of continuous deposition of spent oil in the soil. The physiochemical properties, including heavy metals concentrations, of spent oil contaminated soils and adjacent control soils were investigated at 0–15 and 15–30 cm depths at Ladipo and Berger auto-mobile Markets in Lagos, southwest Nigeria. The soils were collected in triplicate and analyzed in a 2 (location) * 2 (study site) * 2 (soil depth) factorial experiment. The results showed a uniform soil texture in both study sites and at both soil depths, with loamy sand at Ladipo and sandy loam at Berger. Bulk density was significantly decreased, while the total porosity (46.44%), organic C (21.79 g kg− 1), available P (16.48 mg kg− 1), Na+ (0.72 cmolc kg− 1) and K+ (0.81 cmolc kg− 1) increased in the contaminated site compared to the control site. Soil pH was higher at Ladipo (8.4) than at Berger (7.4). However, the soil pH and available P concentration decreased in the contaminated soil compared to the control at both locations, resulting in a decrease in available P concentration of more than 300% and 100% at Ladipo and Berger, respectively. At the Ladipo location, the concentration of Ca2+ was higher in the control than in the contaminated counterpart, while the opposite was true at the Berger location. The concentrations of the heavy metals Pb and Zn in the contaminated soils were low, while the Cu concentration was high. Although the concentrations of these heavy metals were below the standards for potential environmental risks, the high Cu concentration at both locations poses a potential ecological risk and may affect soil and human health as Cu accumulates in critical levels in the soil due to the continued irresponsible disposal of spent oil on the ground.

This experiment was carried out in order to evaluate productivity and rates of poultry manure used to amend kerosene oil contaminated soil on 0.18 ha of land. The land area was contaminated with 5% of kerosene oil equivalent to 50,000 mgkg-1 and thereafter the field laid out using randomized complete block design (RCBD) with four treatments of 10, 20, 30 tha-1 of poultry manure and control which were replicated five times. Maize hybrid (Oba super II) variety was used as an evaluation crop. Results showed except for bulk density, poultry manure amended at 30 tha-1 was significantly (P<0.05) higher by 57, 10 and 56% in total porosity, aggregate stability and gravimetric moisture content (GMC) compared to control. Eventhough, there was no significant (P<0.05) treatment effect of poultry manure amendment on chemical properties of studied soil properties except for sodium, Organic carbon, nitrogen, phosphorus, CEC and base saturation were respectively higher by 33, 17, 37, 27 and 24% in plot amended with 30 tha-1 of poultry manure than when compared to control. Plant height and grain yields of maize followed the trend obtained in improvements of physicochemical properties of soil as reflected by amendments but significant (P<0.05) tallest maize plant and grain yield of maize were obtained in plot amended with 30tha-1 of poultry manure compared to control. Rate of poultry manure is necessary for sustainable productivity of kerosene oil contaminated soil.
