Atrazine Residue and Seedling Establishment in Furrows

Deep furrows made with shovel openers and simulated disk-type furrows were evaluated for removal of atrazine residue from the seeded row and for seedling establishment in the atrazine-fallow technique of range seeding. Atrazine residue in all furrow treatments was below the toxic level for crested and intermediate wheatgrasses. Established stands of both species were similar in all furrow treatments. Therefore, the deep-furrow rangeland drill with disk openers appears suited for large-scale application of the atrazine-fallow technique.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
