“…The urea might have supplied growth limiting nutrient to the plant for metabolic activities thus enhancing (stimulating) the growth and phytoremediation potential of Chromolaena odorata in the polluted soil [38][39][40]. Shtangeeva et al [41] also report that the addition of urea to crude oil polluted soil enhanced the growth of wheat in such soil. It can thus be deduce that the plant provided an enabling environment for microbial increase at the root area of the plant thus encouraging microbial degradation of the hydrocarbon pollutant [42,43].…”

Investigation on the use of urea in stimulating the phytoremediation of Chromolaena odorata in a crude oil contaminated soil was carried out at a crude oil spilled site at Botem-Tai, Ogoni, Nigeria. Three phytoremediation treatments labeled A – C in addition to the control (D) were used. The treatments were: A (Chromolaena odorata only), B (Chromolaena odorata + 20 g/m2 urea), C (Chromolaena odorata + 40 g/m2 urea), D (polluted soil without phytoremediation) arranged using Latin Square Design (LSD). Total petroleum hydrocarbon (TPH) and Total hydrocarbon content (THC) in soil and plant samples from the different treatment plots in addition to other soil nutrients were analyzed. The percentage reduction in TPH and THC in soil were as follows: Treatment B, {TPH (92.08%) and THC (95.37%)} > treatment A {TPH (88.95%) and THC (93.37%)}> C {TPH (78.78%) and THC (83.29%)} > Control {TPH (14.76%) and THC (32.90%)}. Treatment C had the highest TPH (2.67 mg/kg) and THC (20.57 mg/kg) accumulation in test plant. Combining stimulant (urea) with phytoremediation also improved soil properties such as pH, Nitrogen and Potassium. With the highest reduction of TPH and THC in treatment B (phytoremediation with 20 g/m2 urea) than other treatments is an indication that low concentration of urea has a stimulatory effect on phytoremediation of crude oil by Chromolaena odorata.

“…[23] reported that high dose of nitrogen and phosphorus was able to restore the productivity of an eroded alfisol to the original top soil level in southern Nigeria. [13,23] have also shown that adequate irrigation was necessary to compliment the benefits of added organic fertilizers. Similarly, [13] showed that amendment of contaminated soil with urea enhanced the effect of phytoremediation and the decrease of Cadmium concentration in the soil was more significant.…”

“…[13,23] have also shown that adequate irrigation was necessary to compliment the benefits of added organic fertilizers. Similarly, [13] showed that amendment of contaminated soil with urea enhanced the effect of phytoremediation and the decrease of Cadmium concentration in the soil was more significant. The best effect was demonstrated after application of "ispolin": concentrations of Cd, Cu, Pb, and Zn in the rhizosphere decreased 1.2 -1.4 times as compared with those in the initial contaminated soil (the decrease was statistically significant).…”

The study is aimed at evaluating the effectiveness of phytoremediation in the management of oil impacted soil in Ekpan communities of Delta state, Nigeria. To do this, the study adopted an experimental research design that involve the use of phytoremediation (carpet grass Axonopus compressus) and nutsedge Cyperus rotundus) in the management of petroleum impacted soil site in Ekpan, This experiment spans for three months periods (one planting season). It involves the treatment of the oil impacted site with different plant species and soil amendments. Laboratory analysis of the soil samples was conducted to determine the effect of phytoremediation and soil amendments on hydrocarbon loss in oil impacted sites. The study revealed that the combined effect of Axonopus sp., Cyperus sp. and oil amendments accounted for 59% reduction in hydrocarbon. However Axonopus sp. and Cyperus sp. accounted for 47% and 48% reduction in hydrocarbon respectively. This shows that though, both plant species can be used successfully as a phytoremediation technique for the reclamation of oil impacted soils, but Axonopus sp. and Cyperus sp. was the most effective when applied with soil amendment (organic and inorganic manure). It is therefore recommended that iindigenous plant species (particularly Axonopus sp. and Cyperus sp.) should be used together with soil amendments in phytoremediation rather than the traditional bioremediation involving the use of microorganism. Oil companies operating in the Niger Delta region of Nigeria are encouraged not only to carry out physical clean-up of oil spills but should also carry out bioremediation to restore the environment back to its natural or near natural state. The methodology adopted in this study could be followed by oil companies to manage oil impacted soils in the Niger-Delta environment in Nigeria and indeed everywhere in the world

“…In the phytoremediation of organic pollutants based on microbial degradation in the rhizosphere, fertilization is essential for success to reduce competition between plants and microorganisms for limited nutrients in polluted soil. Only a very few workers have made use of inorganic chemical fertilizer as an amendment agent to improve phytoremediation in the enhancement of petroleum hydrocarbon degradation (Hutchinson et al, 2001;Shtangeeva, 2004;Efe and Okpali, 2012).…”

This study investigated the potential effect of poultry dung (biostimulation) and stubborn grass (Sporobolus pyramidalis) (phytoremediation) on microbial biodegradation of gasoline and nickel uptake in gasoline-nickel-impacted soil. In addition, the potential stimulatory effects of nickel on hydrocarbon utilization were investigated over a small range of nickel concentrations (2.5-12.5 mg/kg). The results showed that an increase in nickel concentration increased hydrocarbon degraders in soil by a range of 8.4-17.2% and resulted in a relative increase in gasoline biodegradation (57.5-62.4%). Also, under aerobic conditions, total petroleum hydrocarbons' (TPH) removal was 62.4% in the natural gasoline-nickel microcosm (natural attenuation), and a maximum of 78.5%, 85.7%, and 95.8% TPH removal was obtained in phytoremediation, biostimulation, and a combination of biostimulation-and phytoremediation-treated microcosms, respectively. First-order kinetics described the biodegradation of gasoline and nickel uptake very well. Half-life times obtained were 28.88, 18.24, 14.44, and 8.56 days for gasoline degradation under natural attenuation, phytoremediation, biostimulation, and combined biostimulation and phytoremediation treatment methods, respectively. The results indicate that these remediation methods have promising potential for effective remediation of soils co-contaminated with petroleum hydrocarbons and heavy metals.
