Technical Abstract: Soil column experiments are being carried out to evaluate low-cost methods of reducing fumigant 1,3-dichloropropene (1,3-D) release from soil to air. A further aim of the work is to determine how well data derived from the soil columns compare with data derived from field experiments. A sandy loam soil from an experimental site previously-used to study 1,3-D volatilization in the field, is packed into stainless steel columns (12 cm diameter × 1.5 m length). Soil bulk density, moisture content and temperature are close to those observed in the field experiment. After injection at 46 cm depth, temporal trends in the release of 1,3-D from the soil surface and its distribution throughout the soil profile, are being quantified. Data will be presented for replicated volatilization-reduction treatments, e.g., surface irrigation, agricultural film coverage, chemical amendment, and organic amendment. Comparisons with data from the field study will also be made.
