Respiration Studies on Soil Treated with Some Hydrocarbons1

  1. Ann L. Dobson and
  2. H. A. Wilson2



Respiration studies, as measured by the uptake of O2, were made upon oil-free and oil-impregnated soils. A modified Haldane apparatus was used. Composite soil samples of oil-impregnated soil obtained around oil wells showed greater biological activity than samples of oil-free soil. The respiration rate was greater, however, in oil-free soil cores than with oil-impregnated soil cores. Crude oil, kerosene, and mineral oil were added at 2, 10, and 20% on a volume-weight basis levels to a soil. Each percentage addition resulted in its own biological activity pattern but in general the trends were similar. In all cases, the soil with added hydrocarbon had a greater respiration rate than the untreated soil.
