What should be monitored regularly throughout the storage life of corn?

Monitoring moisture content and temperature throughout the storage life of corn is crucial for maintaining grain quality and preventing spoilage. High moisture levels can lead to mold growth and deterioration of the grain, while temperature affects the metabolic processes and can encourage insect infestations. By keeping the moisture content within an optimal range and monitoring temperature, one can ensure the corn remains in good condition and reduces the risk of loss due to spoilage or pest activity.

The other factors listed, while they may have some relevance, do not play as significant a role in the overall management and preservation of stored corn. The color of the grain may indicate some quality issues but is not a direct measure of deterioration or storage condition. The height of grain stacks might be relevant for safety or management concerns but doesn't directly relate to the grain's storage viability. Identifying the type of pests present is important but should be secondary to ensuring optimal storage conditions, as pest control measures are more effective when grain conditions are properly managed.
