Abstract
Farmers in the irrigated Columbia Basin of eastern Washington are using a variety of soil improvement practices: (1) organic amendments, (2) cover crops and green manures, and (3) high residue farming. To determine the effects of these practices, we compared the soils of fields managed under these practices to adjacent fields with no soil improvement practices. The soils were evaluated through an array of measurements in 2015. Results show that these practices can maintain or improve soils in this region, though each practice differs from the others in its specific effects. A parallel study estimated the economics of soil improvement and found that the improvement practices generated positive returns on investment.
