Field experiments were conducted to measure subsurface movement and volatilization of the 1,3-dichloropropene (1,3-D) after shank injection to an agricultural soil. Aerodynamic, integrated horizontal flux and theoretical profile shape methods were used to obtain fumigant flux density and cumulative emission values for two emission-reduction methods: (a) repeated surface irrigation and (b) surface-soil amendment with organic matter. The volatilization rates were measured continuously for 16 days and total emissions were found to be approximately 30-50% less than observed in other studies. Significant reductions in volatilization of 1,3-D are possible when repeated surface irrigations or organic amendments are applied to a field.
