Other Corn Production Issues

Early Season Cold Stress Frost damage in May or June will generally have little impact on the crop, provided the growing point of the corn plant is still below the soil surface. This is the case until the young plant reaches roughly the sixth-leaf stage (V6). On more advanced plants and/or where damage is more […]

Storage

Corn Drying The three general types of grain dryers used on the farm are: No single drying system is superior. Grain dryer selection is dependent on desired features, including drying capacity, grain quality, fuel/drying efficiency (BTUs per volume of water removed), convenience, manpower required to run the dryer, ability to dry a variety of crops, […]

Harvesting

Harvesting Physiological maturity (black layering) occurs when the grain moisture content reaches 31%–33% moisture. After this stage, there is no dry matter added to the corn kernel. Harvesting grain corn at moisture contents above 28% often results in significant damage to the grain and makes it more difficult to market commercially. High quality food grade […]
