Use of Rotational Stocking in Combination With Cultural Practices for Smutgrass Control-A Florida Case Study

On the Ground
- Smutgrass (Sporobolus indicus) is an invasive plant in Florida sandy soils, prevalent in central and south Florida where temperatures seldom drop below freezing and hard frost events are infrequent.
- Smutgrass becomes nonpalatable to cattle as it matures and cattle avoid grazing it after the emergence of seed stalks and when leaves become tough. However, young smutgrass growth is palatable to cattle.
- High stocking densities in combination with severe defoliation have proven deleterious for this grass. This study evaluated the use of increased stock density and rotational grazing management for 3 years following a one-time defoliation by mowing or burning smutgrass infested pastures.
