Use of Macro-Minerals of Fluted Pumpkin in Evaluation of Remediation Potentials of Crude Oil Impacted Soil by Cow Horn Powder at Ikwerre Local Government Area, Rivers State, Nigeria

Abstract

The objective of this work is to assess the remediation potentials of cow horn powder using fluted pumpkin grown on crude oil contaminated soil at Ikwerre Local Government Area, Rivers State, Nigeria using appropriate standard methods. Data shows that the ZgCH group showed a better treatment than XgCH and YgCH in enhancing the level of the minerals (Na =67.1±0.00, N = 111±0.41, Ca = 493±0.00) when compared with the level of the minerals in the -Ve C (Na = 39.0±0.06, N = 65.4±0.03, Ca = 367±0.00). The results after the 8th week of remediation showed that cow horn powder significantly improved the macro minerals concentration of fluted pumpkin leaves grown on crude oil-impacted soil across all the cow horn powder treated groups compared to the -Ve C and NC groups. In conclusion, cow horn powder can enhance the mineral concentration of plants grown on crude oil-impacted soil.
