Abstract or Summary
  • A field study on grass field burning was conducted in the Willamette Valley of Oregon during the summer of 1965. Approximately 243,000 acres of grass fields are burned in the valley during August and September. Serious air pollution problems result from this burning. The purposes of the study were to determine the effect of environmental variables on grass field burning and to determine if conditions exist when significant air pollution reduction can be achieved. The environmental variables investigated were time from harvest to burning, time of day, air temperature, relative humidity, soil and straw moisture, wind speed and direction, and fuel density. The dependent variables measured were particulate emission and size distribution, combustion temperature, burn rate, amount of residue, percent of organics in the particulate, and smoke appearance. The results were analyzed statistically using a correlation matrix and a stepwise multiple linear regression analysis to determine the significant variables and their relationship. Environmental variables were found to affect the grass field burning process causing significant differences in some of the dependent variables.
