Runoff and soil loss plots were established at several sites in eastern WA to examine the effect of grass sod at various stages of management. Runoff and soil loss were high on a new grass seeding. Burned grass fields had high runoff but low soil loss. The first wheat crop after grass had high runoff and soil loss due to intense tillage. Winter wheat on land with no grass history had larger runoff and soil loss than when seeded the 3rd year after plowout. Use of no-till seeding can reduce erosion during the hazard years of a grass system. Runoff was lowest in the wheat in the 3rd year after grass.

Relative runoff from 27" rainfall over 15 months on plots with 10% slope: prairie 2.5%; overgrazed pasture 9.1%; bare soil 15.1%. Water penetration was nearly four times as great in prairie as in pasture. Even with runoff, no measurable erosion occurred on any of the grassed plots.
