Nebraska Extension is encouraging producers to focus on key fall pasture and forage management practices, including alfalfa irrigation, thistle control and managing late-summer annual grasses. Ben Beckman, Nebraska Extension educator, said these strategies can help improve pasture productivity and prepare fields for the next growing season.
One important recommendation is evaluating soil moisture before shutting off irrigation in alfalfa fields. Although alfalfa uses less water in the fall, adequate soil moisture remains important for plant health, root development and winter survival.
Fall irrigation can also help replenish deeper soil moisture reserves that were depleted during the growing season. Producers should base irrigation decisions on soil moisture conditions, while also considering soil type and local irrigation restrictions.
Fall is also an effective time to control thistles in pastures and hayfields. Producers are encouraged to scout treated areas for regrowth, as species such as musk, plumeless, bull and Scotch thistle can be managed more effectively during their rosette stage.
Canada thistle requires a different approach because it spreads through both seed and underground roots. Fall treatments are often more effective because actively growing plants are moving nutrients into their root systems, improving herbicide movement throughout the plant.
Late-summer annual grasses such as foxtail, sandbur and barnyardgrass are another common concern. These weeds typically become more noticeable in thin or overgrazed pastures where open spaces allow them to establish.
Control options are limited once annual grasses have matured and begun producing seed. If seed production has not been completed, mowing may help reduce future infestations.
Long-term management depends on maintaining healthy, competitive pasture stands through proper stocking rates and adequate recovery periods between grazing. Beckman noted that proactive management can help producers improve forage productivity, reduce weed pressure and strengthen pasture performance over time.
