Abstract
In world agriculture; such as the one implemented in Mexico; the use of fossil fuels in machinery for soil preparation and harvesting of an agricultural crop is common. As a result; waste residual oil (WMO) is generated in that sese agricultural soil impacted by 80;000 ppm of WMO exceeds the limit of 4;400 ppm of hydrocarbons according to Mexican environmental regulation NOM-138-SEMARNAT/SS-2003 (NOM-138). WMO causes loss of fertility and environmental pollution. A sustainable strategy of solution is biostimulation and phytoremediation.The aims of this research were:
i) Biostimulation of an agricultural soil impacted by 80;000 ppm WMO then by
ii) Phytoremediation sowing H. annuus inoculated with B. vietnamiensis and P. polymyxa to reduce WMO at concentration value below the NOM-138 maximum. The variable-response variables of WMO bioelimination from an agricultural soil were: initial and final WMO concentration by Soxhlet; phenology and biomass of H. annuus with B. vietnamiensis and P. polymyxa. Experimental data were validated by ANOVA/Tukey HSD P
