Effect of Oil Refinery Sludge on Plant Growth and Soil
High Ca contents of plants are associated with high Ca contents of ORS which ranged from 10.30-10.93% ( Table 1 ). Effect on soil chemical properties: Men soil salinity and sodicity increased slightly due to the addition of ORS ( Table 5 ). The soil pH
Effect of Oil Refinery Sludge on Plant Growth and Soil Properties
The Oil Refinery Sludges (ORS) were rich in total plant nutrients and organic matter but low in the available form of plant nutrients. The application of ORS, being rich in organic matter, can improve the productivity of sandy soils provided supplemented with inorganic (NPK) fertilizers.
Effects of oil contamination on plant growth and development
Oil spills generate several environmental impacts and have become more common with the increase in petroleum extraction, refining, transportation, and trade.
Effect of Oil Refinery Sludge on Plant Growth and Soil Properties
Petroleum oil spillage on soil generally retards plant growth and soil productivity (Rowell, 1977;Ladousse and Tramier, 1991;Okpokwasili and Odokuma, 2007), reduces aeration by blocking...
Effect of Oil Refinery Sludge on Plant Growth and Soil Properties
Petroleum oil is spilled on soils due to several factors including pipeline destruction (Nwilo and Badejo, 2001; Al-Qahtani, 2011). Petroleum oil spillage on soil
Effects of oil contamination on plant growth and development
Abstract. Oil spills generate several environmental impacts and have become more common with the increase in petroleum extraction, refining, transportation, and trade. In soil, oil contamination increases water and nutrient availability and compaction, directly affecting plant growth and development. Different aspects of phytotoxicity can be

(PDF) Effect of oil refinery sludges on the growth
In this study, the effect of the addition of petroleum sludge to soil on the physiological parameters, nutrient contents, and oxidative and antioxidant status in alfalfa was investigated. An
The effect of oil sludge contamination on morphological
For all species, the greatest seedling emergence rates were recorded in their control pots. In the soils contaminated with 10, 20 and 40% of oil sludge, seedling emergence significantly decreased for A. altissima Mill. (P < 0.01) up to 38, 46 and 63%, respectively. The lowest decreasing rate of seedling emergence belonged to F. rotundifolia in that...scialert.net
Effect of long-term application of oil refinery wastewater on
An experimental field at Mathura receiving oil refinery treated wastewater (TW) since the last 12 years is under study. Wastewater of the oil refinery contains a traceable amount of heavy metals, therefore, its continuous application has resulted in the accumulation of these heavy metals in the soil (Aziz et al., 1996; Hayat et al., 2000).
