Study Examines Effect of Grazing Sheep on Vegetable or Cover Crop Plots

Researchers at Montana State University are exploring the effect that grazing sheep on vegetable or cover crop plots has on soil health. They are studying how using grazing sheep for weed control might reduce the need for tillage or chemical herbicides. After two years of in-field testing on three cooperating farms, they’ve found that grazing sheep add fertility to the soil, reduce the need for tillage, and don’t appear to cause soil compaction. The third year of the Western SARE-funded project involves outreach to producers in the form of tip sheets, workshops, videos, and write-ups.
