Many livestock producers are questioning whether their alfalfa stands  are at risk of winterkill. In early January, many fields were covered with 1-2 in. of solid ice, which may raise the risk of winterkill in alfalfa.
How old is the stand? Alfalfa stands  often become thin and less productive after the third year. Harsh winter conditions can exacerbate this decline with advancing age.
Plants  that are 1-2 years old are generally more stress-tolerant than older ones because they've been exposed to less physical damage and disease.
