Abstract
This invention provides a process for fumigating a plot of ground soil which involves dispersing a particulate ammonium carboxylate such as ammonium bicarbonate on or below the ground surface, followed by covering of the treated ground area with a tarpaulin to seal the ground surface from contact with the atmosphere. The tarpaulin covering is maintained on the ground surface for a sufficient time period to allow decomposition of the ammonium bicarbonate into a mixture of ammonia and carbon dioxide gases, and to effect fumigation of the covered plot with the generated gas mixture.
