Sheep Grazing to Manage Crop Residues, Insects and Weeds in Northern Plains Grain and Alfalfa Systems
SARE-funded research at Montana State University has demonstrated that using sheep to graze crop residue and summer fallow can address many challenges faced by wheat and alfalfa growers in the Northern Plains. Researchers found that sheep were effective in controlling alfalfa weevil, provided an environmentally friendly alternative to herbicides and pesticides and allowed the grower to manage erosion by controlling the amount of remaining residue.
The researchers also developed an economic tool that allows the user to estimate treatment scenarios for alfalfa weevil management by comparing input costs of either insecticides or grazing sheep.
