Description :
The aim of this study was to assess wind erosion and PM10 emissions from soils subject to conventional and undercutter tillage during the summer fallow phase of a winter wheat-summer fallow rotation within the Columbia Plateau region of the Pacific Northwest US. The field plots were instrumented after disking or undercutting in spring 2005 and 2006 to monitor horizontal soil flux and PM10 concentration at the windward and leeward positions. Results and discussion about management practice to reduce dust emissions from agricultural sites and therefore to protect the ambient air quality.
