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.

Promising new legumes - milk vetch species, big headed clover, flat pea, siberian alfalfa, black medic, trailing birdsfoot, sanfoin, lupin, Montana goldenpea, perennial vetch. Yellow sweetclover was superior to white under drought conditions; dwarf varieties recommended in drier areas; clipping sweetclover reduced vigor, hay yield and total N per acre; Ladak the best alfalfa variety for the region.
