Bioremediation Study of Crude Oil Polluted Soil with Water Hyacinth (Eichhornia Crassipes) and Spent Mushroom Compost

A lot of hazard from polluted environment in the Niger Delta have obstructed Ecosystem balance, comparing bioremediation study with water hyacinth (Eichhornia crassipes) have done good to the environment analysis to ascertain the Stoichiometric loss in TPH which ranging from, Changes in soil nitrate and phosphate levels, Levels of heavy/trace metals, Changes in soil pH composted soil was tested for bioremediation of aged crude oil-polluted soil. spent mushroom compost, water hyacinth compost, water hyacinth compost + spent mushroom compost, and unamended soil were all applied at 10% each to 1000g of polluted soil. TPH degradation occurred in the following order: control< SMC < WHC< SMC+WHC. All treatments increased TPH with WHC having the highest bio-stimulatory effect followed by SMC+WHC. This study will help in restoration of agricultural land and bio-diversity and large scale control of water hyacinth in Nigerian waters, the research is necessitated by the need to proffer an appropriate solution to the menace of Water Hyacinth (Eichhornia crassipes) in Nigerian fresh waters. In addition, this research will address the insufficient supply of biofertilizer to improve crude oil impacted sites in the Niger Delta. As a supply of limiting nutrients required for the bioremediation of crude oil-impacted media, organic nutrient sources like Eichhornia crassipes nutrient powder are beneficial.
