The North Dakota State University (NDSU) Extension recently evaluated the impact of grazing use intensity on grassland growth and production.
Their study, conducted at 51 locations across 12 North Dakota counties, found that pastures with slight to moderate grazing use saw the highest growth, while severe grazing reduced forage production by as much as 57% in 2022 and 54% in 2023.
Lead researchers Miranda Meehan and Kevin Sedivec emphasized the importance of grazing management, noting that “The results of this program demonstrate the importance of having a grazing management plan and monitoring grazing use to reduce long-term impacts to grazing resources.”
Producers are advised to avoid grazing grasses below three to four inches of stubble height. This ensures that cool-season grasses can store carbohydrates necessary for surviving winter and regrowing in spring. Penn State Extension highlights that stubble height is particularly crucial in the fall, when perennial grasses undergo root regeneration.
South Dakota State University (SDSU) Range Management Specialist Sean Kelly also stresses the importance of maintaining stubble height, stating that overgrazing during fall can remove the growing point of cool-season grasses, preventing their growth the next season.
NDSU recommends calculating proper stocking rates to avoid overgrazing, a key to effective pasture management. Monitoring tools like the grazing stick help track pasture utilization and determine when livestock should be removed. Proper pasture management, including giving grasses time to rest and regrow, ensures long-term productivity and sustainability.
Finally, University of Minnesota Extension Forage Specialist Craig Shaeffer suggests paying attention to weed growth, which can proliferate when drought conditions weaken cool-season grasses.
