This was demonstrated on the density and distribution of Azotobacter vinelandii within the polluted soil. This was observed in October 2006, for a parcel of land having more than 9,500 matured oil palm trees in Owaza, Nigeria where a massive oil spill occurred. The result showed that there was a significant reduction in nitrogen fixation in the crude oilcontaminated oil palm plantation as exemplified in the population and distribution of Azotobacter vinelandii. These diazotropic bacteria play important roles in the stability of the ecosystem, agriculture and marine productivity. There was a significant reduction (p
