| Soil can be eroded by sprinkler or surface irrigation. Once sprinkler droplet kinetic energy detaches soil, overland flow transports the sediment downslope and off-site. Protecting the soil surface, increasing sprinkler wetted diameters, and tilling to increase infiltration and thereby lessen overland flow are effective control measures. Runoff minimization and management are key to reducing erosion induced by either sprinkler or surface irrigation. Slowing furrow stream velocities with mulch or crop residues reduces the flow’s hydraulic shear and, in turn, detachment of soil from furrow wetted perimeters. Stabilizing surface soil with, for example, polyacrylamide, bio-polymers, or whey keeps soil in place and helps maintains acceptable water quality in... |

| Irrigation transformed arid land in the Pacific Northwest into productive agricultural land. However, much of this land is prone to erosion during irrigation, which can cause problems on and off of the field. Management practices have been developed to control soil erosion on irrigated land and improve the quality of water returning to streams and rivers. Applying polyacrylamide (PAM) with irrigation water can reduce erosion from furrow irrigated fields more than 90%. Using PAM in combination with other practices, such as applying straw mulch in furrows and installing small sediment ponds on fields, can virtually eliminate sediment loss from fields. Once soil runs off a field, it can be removed by settling in sediment ponds, although soluble... |
