Dust emission factors for regional-and local-scale simulations of particulate matter with diameters less than or equal to 10 u,m (PM|") dispersion from agricultural operations are not generally available. This article presents a modification of the U.S. Environmental Protection Agency AP-42 approach to better calculate aerosol emission factors of PM, (I for agricultural tilling operations. For the modification, we added the variables soil moisture, operation type, and crop type based on

Field experiments to measure the PM| 0 emissions from rolling, disking, listing, planting, and harvesting cotton (Gossypium hirsutum L.) were conducted. Data from these field experiments plus literature data were used to isolate the effects of soil moisture and operation type on the emissions. Literature data were then used to add different crop and operation types.
