Effects of the amendment of crude – oil polluted soil on fungal population

Abstract

The population of fungal propagules in crude oil polluted and amended soil under simulated condition was investigated. The result showed an initial decrease in the population of fungal propagules, then a rapid increase and finally, a gradual reduction in the number of propagules. An exception to this was in sawdust-amended soil that recorded a rapid increase in fungal population from the beginning up to the 4th week. The polluted and unremediated soil showed a comparatively low fungal population up to the 3rd week before a gradual increase. The soil amended with wood ash showed a comparatively low population of fungal propagules throughout the study.
