Excessive tillage—especially in the low-precipitation wheat production region of the Inland Pacific Northwest—causes blowing dust, which results in soil loss as well as air quality degradation. Yet more than 90% of rainfed cropland in the Inland PNW is on a two-year, tillage-based winter wheat-summer fallow rotation. The undercutter system was developed to mitigate wind erosion and achieve profitable yields. This publication outlines the results of a multi-year, on-farm study conducted with 47 farmers who adopted the undercutter method.
