" . . . Inipol (an
“oleophilic” fertilizer) is a stable
water-in-oil formulation that yields
an
N-P-K
ratio of
7.3 :
0.8
: 0.
The
nitrogen source is urea
and the
phosphorus
source is trilaureth (4)-phosphate."
"At room temperature, Inipol
has the consistency and appearance
of honey, and it must be heated to
90oC (194oF)
* before it can be
sprayed on the soil. Inipol was
applied as a thin coat to the shore
at a rate of 306 ml m-2
(0.27 quart per square yard). As the
microemulsion mixed with the
weathered crude oil, the crude oil
destabilized Inipol to release its
urea-N.
"
"In
addition, a surface-active organic
material (oleic acid) in Inipol
served as a readily degradable
carbon and energy source
to increase the activity and number
of indigenous hydrocarbon-degrading
bacteria. When the
oleic acid
was depleted, the increased biomass
of hydrocarbon-degrading bacteria
supported enhanced biodegradation of
the petroleum."

bioremediation also
undoubtedly occurred in
the absence of the
fertilizer nitrogen
