The objective of this research was to obtain comparative flux data for  several alternative versions of Bayfilm in comparison to TIF tarp  material.  The test medium of this study was four agricultural test plots, of which tarp type was the primary test variable.All four fields were adequately separated, prepared similarly, and applied with PIC Chlor 60 EC� fumigant (~60% chloropicrin and ~40% 1,3-dichloropropene). Air and soil sampling was conducted on each of the four fields from the date of the application.  Sonic meteorological sensors were established at pre-determined heights on each field to establish a vertical flow profile representative of field-specific meteorological conditions.  This vertical profile, in conjunction with the measured vertical concentration profile of chloropicrin and 1,3-dichloropropene concentrations were the primary inputs used to calculate emission rates at each field.  In addition, soil sampling was conducted at two depths for chloropicrin and 1,3-dichloropropene for concentration analysis.
