Cover: USDA-ARS scientists have investigated the effects of conservation practices such as direct seeding and maximal residue management on the productivity, economics, and soil erosion of perennial grass seed crops grown in western Oregon. Grass seed is grown in close proximity to urban population centers and to seasonal drainages that provide winter habitat to native fish. Due to air and water quality concerns, farmers in the region were looking for economical alternatives to burning straw after harvest and ways to protect water quality. This research has shown that producers using conservation practices can still make a profit while protecting natural resources.
