Cold On Small Grain

Cabbage-Frost 010

Cabbage-Frost 011Here is some wheat from last week that was showing some cold burn on the leaves. We got down to 21 degrees on Jan 8th. This burn will not be a problem in wheat since we are so early in growth stage and heads have not emerged. The main issue is slowing down growth. With forage crops, cold duration can hurt us since we are so slow in establishing our forage.  Seminole County Agent Rome Ethredge talked about leaves farthest from the ground have the worst damage. This is because water has a high specific heat, therefore moist soils will hold heat better. We may also see more damage where soils are dry for this same reason.
