Microbial Activities in Fertilizer-Amended Contaminated Soils

Bioremediation, an affordable and environmentally friendly technique, remains a viable strategy for tackling water and soil pollution. This study investigated microbial activities in crude oil-contaminated soils amended with fertilizer. Unpolluted soil samples obtained from the bed of Ovia River, Benin City, Nigeria, were contaminated with crude oil, and thereafter remediated with NPK/urea fertilizer. Textural classification of the soils showed that the clay soil contained 77 % clay, while that of the sandy-clay soil was 72 %.
