The correct moisture range for harvesting whole plant corn silage is typically around 65-70% moisture. This moisture content is crucial because it ensures that the corn silage will ferment properly in the silo, creating an environment that promotes lactic acid fermentation, which helps preserve the forage longer and improves palatability for livestock.

Harvesting at this moisture level helps avoid both the risks associated with insufficient moisture, such as inadequate fermentation and spoilage, as well as issues linked to overly wet silage, which can lead to nutrient leaching and undesirable fermentation processes. This balance is vital for achieving high-quality silage that maintains its nutritional value and supports animal health and productivity.

In contrast, the other moisture levels provided in the options either fall outside the optimal range for fermentation or are associated with different stages in the crop's development. Such incorrect moisture levels would compromise the silage's quality, affecting both its storage and the nutritional intake for animals.
