A series of field trials using a chemical simulant was conducted on sandy soil in the Experimental Proving Ground of the Defence Research Establishment Suffield, located near Medicine Hat, Alberta, Canada. Seven trials were conducted with methyl salicylate thickened to a zero shear viscosity of six poise. Explosive dissemination was used to provide liquid drops. The measured total dosage fifty metres downwind of the contaminated area was predicted by means of a previously developed mathematical model. The results of these trials are compared to those of similar trials conducted on prairie grassland.
