Abstract:
Oil pollution causes changes in the physical, chemical, and biological properties of soils, including a change in the pH buffering capacity of the soil to resist the change in the acid and alkaline range, which in turn affect nutrients absorption soil fertility. This research aimed to study the effect of oil pollution on pH buffering capacity to change acidity and alkalinity values of some soils in Al-Hasakah governorate, Al-Malikiyah (Vertisols) and Rmelan (Inceptisols). The research carried out under laboratory conditions using oil pollution treatments with different proportions T1: control 0 ml/kg, T2: 5 ml / kg, T3: 50 ml / kg, T4: 100 ml / kg.The results showed a decrease in pH buffering capacity of Malikiyah soil (Vertisols) to resist change in soil acidity in the acidic range when oil pollution increased, a decrease by 1.95% at T2 treatment, whereas at T3 and T4, pH buffer capacity decreased by 6.73- 8.39% compared to control respectively. While the pH buffering capacity of Malikiyah soil in the alkaline range increased with the increase in pollution levels. The pH buffer capacity of Remelan soil (Inceptisols) was 73.35% in the acid range and 26.65% in the alkaline range in control soil , and decreased in acid range by 0.89%, 5.72%, 8.48%. While it increased in the alkali range with increasing levels of oil pollution. When comparing the two soils, Al-Malikiyah soil had a higher pH buffering capacity compared to Remelan soil in the acid range, whether in control soil or on oil polluted treatments.
Keywords: Oil pollution, pH buffering capacity, Al-Hassakeh soils, Al-Malikiyah soil, Remelan soil.
