An Iowa farmer sent me an email in anticipation of the freeze this weekend and I suspect many farmers are in the similar position of having mature crops with replant that may not be mature yet. Read more about my thoughts on how to handle this situation below.

A portion of Iowa’s corn crop is likely to experience a frost before naturally reaching maturity as a result of cool temperatures later this week. Natural maturity is often determined when a black layer is formed at the kernel tip. At this timeframe grain moisture is typically 28–35% moisture....

Sampling corn stalks this fall will likely be later than normal due to the delayed planting in many Iowa cornfields. The overall suggestion is to wait until crop maturity, and sample within 1-3 weeks after kernel black layer. This does not work well for silage corn, so the suggestion is to...
