Abstract |
Research on an 800-hectare irrigated tract in central Washington's Columbia Basin Project studied the effects of on-farm improvements on reduction of the discharge of sediment and nutrients via irrigation return flow. Technical assistance and financial cost-sharing were provided to participating farmers. Physical improvements included pipes to convey tailwater to improved drains, sediment basins and mini-basins, concrete lining of head ditches, gated pipe systems, and conversion of furrow irrigated land to sprinkler systems (center pivot and solid set). Structural improvements greatly reduced the sediment discharge from the overall tract. Measures which controlled sediment loss were not equally effective in reducing phosphorus loss, even though reductions in phosphorus loss were significant. |
