In 1932, J. O. Smith, Agricultural Engineer at Delta Branch Experiment Station in Stoneville, MS, attached a small anhydrous ammonia cylinder to a plow in such a manner that the NH3 was released in the soil. The plow, a Georgia Stock, was pulled by a gray mule named Ike. This was the first known use of anhydrous ammonia as a soil-applied crop fertilizer. The crude apparatus and the anhydrous ammonia it applied provided a much needed source of nitrogen for the otherwise rich alluvial soils of the Mississippi Delta.

However because it is such a hazardous material and is difficult to apply, many farmers choose to hire third party businesses to store and apply the fertilizer.
