Technical Abstract: Recent studies indicate that bromine produced by methyl bromide contributes to the ozone destruction in the stratosphere. To reduce the anthropogenic input resulting from emissions during soil fumigation, application methods and soil management techniques that can significantly minimize methyl bromide volatilization should be developed. A closed, packed-column system was used to examine the effect of different injection depths, use of surface cover and various soil factors on methyl bromide volatilization rate. Methyl bromide volatilization can be minimized by combing deep injection, surface covering, soil surface packing, and adjusting soil moisture content to a higher level before application. Injecting methyl bromide at a shallow depth into dry, loose soil under uncovered conditions will result in maximum volatilization, and therefore should always be avoided.
