What moisture level is considered optimal for harvest of grain corn?

The optimal moisture level for the harvest of grain corn is typically between 15-20%. However, the range given in the provided answer choice is slightly wider, and while it suggests moisture levels on the higher end (21-28%), harvesting at this level might be influenced by specific conditions such as market demands and drying capabilities.

Harvesting grain corn at this moisture range allows for a balance between grain quality and ease of harvesting. Corn that is too wet at harvest can lead to problems such as lower kernel quality, increased risk of mold and spoilage during storage, and extra costs associated with drying the grain down to acceptable levels for storage or sale. Conversely, if corn is harvested too dry, it may lead to increased breakage and loss of grain.

Understanding the importance of moisture level in the harvest process is essential for optimizing grain quality and ensuring that producers can store and sell their product with minimal issues. Therefore, while the ideal maturation point for harvesting might lean towards lower moisture levels, the option selected represents a practical range that farmers might work with based on current agricultural practices and technology.
