Spent Motor Oil Effects on Soil and Crops¹

ABSTRACT

Spent motor oil was applied to soil to determine the effects on soil and plant growth. At oil rates of up to 31,111 liters/ha, peanuts (Arachis hypogeae L.), cotton (Gossypium hirsutum L.), soybeans (Glycine max [L] Merrill), and corn (Zea mays L.) were successfully grown when amply fertilized, especially with nitrogen. Growth of sorghum (Sorghum vulgare Pers.) and weeds was significantly reduced by high oil rates. Corn grown on recently oil-treated soil contained less nitrogen, and manganese, but the same phosphorus, potassium, calcium, magnesium, and lead as plants grown on untreated soil. Previous oil application increased the manganese and zinc content of corn tissue. Increasing nitrogen application rates increased the growth of corn.

Key Words: N immobilization by oil • land disposal of oil • carbonaceous material • trace element mobilization
