- ... A common cropping system in the intermediate precipitation zone (300 to 450 mm [12 to 18 in]) of the inland Pacific Northwest is the two-year, winter wheat-fallow rotation typically practiced using multiple secondary tillage operations to control weeds and retain seed-zone soil moisture. This crop rotation has proven to be a stable system for producers in this region. However, even conservation ti ...

- ... Contour seeding has long been recommended as a means of detaining water on hillslopes, increasing infiltration, and reducing runoff and soil erosion. Highly undulated landscapes with complex slopes, such as those found in the inland Pacific Northwest, have stymied application of this practice. This study investigated the potential usefulness of using digital elevation models (DEMs) and global posi ...
