The effect of total petroleum hydrocarbons (TPH) levels (4, 6, and 8%), poultry manure (PM), and poultry manure biochar (PMB) on yield, and Cu, Zn, Fe, and Mn uptake in oat plant (Avena sativa) was determined. The results showed that application of 6 and 8% TPHs levels decreased root and shoot dry weight as compared with 4% TPHs level but PM and PMB increased that of parameters. On average, shoot Cu, Zn, Fe, and Mn uptake decreased in oat plants following the application of 6 and 8% TPHs levels as compared with 4% TPH levels. In 8% TPH levels, nutrient uptake significantly reduced by 59.88% for Cu, 52.9% for Zn, 64.61% for Fe, and 62.72% for Mn as compared to 4% TPH levels. However, PMB treatments concluded in an increase in Cu, Zn, Fe and Mn uptake by about 95.5, 47.2, 52.04, and 82.95% in shoot compare with PMB-unamended treatments, and application of PM increased the average of Cu, Zn, Fe, and Mn uptake in oat by 53.46, 31.96, 32.74, and 58.63 % as compared with PM-unamended treatment. It is concluded that the application of PMB and PM in TPHs contaminated soil could significantly improve TPHs dissipation, micronutrient uptake, and growth of oat plants.
