Type: Research



In a field study, conducted at the Teaching
and Research farm of Rivers State University, soil polluted with Bonny Light
crude oil at 0% and 2% v/w was subjected to remediation processes using
vetiver (Vetiveria zizanioides) and
guinea grasses (Panicum maximum)
amended with organic manures for a period of twelve months. Two weeks after
pollution, poultry and Rabbit manures were applied at 0, 10, 20 and 30
tons/ha respectively. Vetiver and Guinea grasses were planted two weeks
later. It was fitted in factorial split plot. Results showed 80% of vetiver
survived in contaminated unamended plots against 85% in control, percentage
survival in guinea grass was 60% in contaminated unamended against 85% in
control. There was initial delay in germination on contaminated plots for the
two grasses. Amendment of the soil with organic manure improves the growth
and performance of the grasses. Vetiver height was significantly (p<0.05)
different from guinea grass in contaminated unamended plots implying that
vetiver has better adaptation to pollution than guinea grass. Remediation of
soil with vetiver and guinea grasses degraded the THC in the soil to 23 and
21% respectively; amendment of soil with different levels of organic manure
increased the level of degradation to 70.6 and 67.9% for vetiver and guinea
grasses respectively. Vetiver uptake of THC in plant tissues was
significantly (p<0.05) different from that of guinea grass. Amendment of
the soil with organic manure reduced the uptake. Generally, both grasses were
tolerant to THC with vetiver being more tolerant with higher survival rate.
Poultry manure as amendment material planted with vetiver grass was more
effective than rabbit manure in remediation of crude oil contaminated soil.
