Abstract
A field experiment was conducted to study the effect of adding diesel engines oil used at different levels and two different species of plants (alfalfa and barley), and two levels of NPK 100 and 50 kg. ha-1 the use of fertilizer, in some soil chemical characteristics, and to determine the efficiency of the plant in the analysis and reduce hydrocarbon oil in the soil. Diesel engine oil was added to the soil at levels of 0, 20, 40 and 60 g. Kg-1 After three months the soil was cultivated in pots. Results showed that there was a significant decrease in the soluble cations in soil from(5.74, 4.32, 1.82,1.41, 6.40, 1.70 and 5.73) Cmol.Kg-1 to (3.51, 2.32, 0.57, 0.63, 3.29, 0.61 and 2.72) Cmol.Kg-1 for all from Ca, Mg, K, Na, Cl, HCO3 and SO4 successively and a significant increase in the concentration of total nitrogen from 0.53 to 0.83 gm.Kg-1, organic carbon 6.5 to 45.2 gm.Kg-1, CEC 18.10 to 23.11 Cmol+.Kg-1 and numbers of microorganisms from 19.7 and 18.4 to 63.21 and 41.23 CFU for all from bacteria and fungi in soil after storing with increase oil levels added. There was also a significant decrease in the concentration values of oil in soil in treatment alfalfa plant and fertilizer additions (100 kg. ha-1) compared with other treatments.
