alfalfa reestablishment, damage by flooding, alfalfa stands
Excess moisture conditions in 1993 caused damage to many stands of alfalfa throughout South Dakota. Floods killed alfalfa in many low-lying areas, and in some instances, entire stands were lost because of excess water. Alfalfa cannot tolerate wet soil conditions for an extended period of time. Several diseases that persist under wet conditions can further damage or even kill alfalfa plants. In addition, standing water can damage plants by reducing oxygen levels necessary for adequate respiration within the plant.
