Hydrocarbons as a class, represent compounds with an excellent store of energy. With this store of energy, in hydrocarbons, they can be thought of as potential sources for plant growth if this energy can be made available.

The objective of this research was to test the effects of soil injection of a particular hydrocarbon, propane, on corn, sorghum, and soybean grain yields at the University of Nebraska field laboratory in Mead, Nebraska.

The result obtained from the field experiments showed that grain yields from corn, sorghum, and soybeans were not influenced by soil injection of the selected propane rates used. Plant growth may be influenced by the effects of the petroleum hydrocarbons and their interactions with the microbes, soil, and plant physiological processes. Increases in nitrogen and organic carbon in soils treated with petroleum hydrocarbons are due primarily to the activities of the microorganisms.
