Approximately 80% of the pastures in Mississippi (MS) suffer from poor and uneven fertility coupled with serious weed management. Close to 90% of the pastures are under continuous grazing, with more than 50% of the forage production being underutilized. To improve the grazing systems in MS, it is necessary to balance the livestock demand with forage availability to promote rapid pasture re-growth (recovery) and increase the opportunity for long-term pasture persistence.
