The Effect of Biostimulation Oil Spill Collection on Winter Rye
The experiment had four groups: a control group, an oil group, a fertilizer group, and a group with both fertilizer and oil. There were three seeds in each of the ten planters per group. Five of these planters contained soil with bacteria, while the other five had autoclaved soil. When applicable, the seed was completely submerged in 20W-50 oil. Quantitative data included: height, angle, and success. Qualitative data included: which rye were green, brown, bent, twisted, and fallen over. Through data and statistics, the hypothesis was supported. The group with fertilizer and bacteria exposed to oil surpassed the oil group significantly and achieved the same rate of growth as the control and fertilizer groups. Early in the trial, the oil and fertilizer group with bacteria was significantly different from the control, but by the end there was no significant difference. This suggests that the oil amount in the soil was reduced to the extent that it no longer inhibited the growth of the winter rye.
