No-till pasture renovation can increase the quality and forage yield of underproductive pastures. Decreased erosion, lower costs, and less lost grazing time are advantages of no-till renovation compared to conventional renovation. Unwanted vegetation is first controlled with herbicides to decrease competition for introduced orchardgrass. Two field trials were conducted using...
