Frost Damage to Soybeans
Blog Post
Temperatures fell into the low 30’s and upper 20’s in most of Iowa over the weekend of October 11-13. Because of the very late planting season, some crops were immature enough to be injured by the freezing temperatures. This ICM Blog will address frost damage concerns to soybeans.
Frost normally forms early in the morning, driven by radiation cooling especially on clear cold nights. The visual impact of the frost damage is most evident the next day (Figure 1).
