AB  - Using laboratory soil chambers a nonscaled representation of an agricultural 
      raised bed was constructed. For a sandy loam soil, 1,3-dichloropropene (1,3-D) 
      and chloropicrin (CP) were applied at 5 cm depth with an excess of water 
      (simulated drip irrigation). Application was made under both high density 
      polyethylene (HDPE) and virtually impermeable film (VIF) covering the soil bed 
      (the furrow was left uncovered). Soil gas distribution of the fumigants, together 
      with emissions into the headspace above the bed, sidewall and furrow were 
      determined over time. Total emissions from the HDPE treatment were cis 1,3-D 28%, 
      trans 1,3-D 24%, and CP 8%. Due to its lower permeability, the values for VIF 
      were 13%, 7%, and 1.5%, respectively. With HDPE, the majority (86-93%) of the 
      emissions occurred from the bed, while for VIF the majority (92-99%) of the 
      emissions was from the furrow. Compared to a range of literature values for shank 
      injection, the use of drip application appears to offer a benefit in reducing 
      1,3-D and CP emissions. However, the most meaningful comparison is with our 
      previous data for simulated shank injection where the same soil was covered 
      (completely) with the same plastic films (1). In this comparison, only 1,3-D 
      emissions under HDPE were lower with drip application; 1,3-D emissions under VIF 
      and CP emissions under both films were greater with the drip application.
