The method of treating hydrocarbon contamination, in soil, that includes providing and operating a rotary tiller having tilling elements that rotate into and out of the soil to till and loosen the soil, and to elevate soil upwardly so that loosened elevated soil then drops downwardly, and is aerated, and dispersing into the soil aqueous streams that contain microbes or chemicals characterized as reacting with hydrocarbon in the loosened soil to produce CO2 and water, thereby to decontaminate the soil.
