A method of enhancing plant growth comprises the step of introducing an alkane into a location adjacent to a plant. The alkane can be introduced intermittently, and can be combined with another gas and/or nutrients. The alkane preferably comprises a butane substrate. The butane substrate can stimulate the growth of butane-utilizing bacteria, such as Aeromonas caviae, Stenotrophomonas maltophilia, Micrococcus varians, Aureobacterium esteroaromaticum, Aureobacterium barkeri, Rhodococcus fascians, Nocardia paradoxus, Comamonas acidovorans and Pseudomonas aeruginosa. The alkane can increase the amount of heterotrophic bacteria in the location adjacent to the plant, and thereby accelerate a heterotrophic nitrification process. The butane substrate can also stimulate the growth of butane-utilizing fungi. The method can also enhance the growth protists and/or prokaryotes. A system for enhancing plant growth in accordance with the method is also disclosed.
