High-moisture corn should be harvested at 24 to 33 percent moisture for optimum storage (maximum moisture of 40 percent). Harvesting corn at these moisture levels may require adjustments to harvest equipment to ensure grain is removed from the cob uniformly.
How dry should corn be when harvested?
Growers should only dry or harvest corn below 15.5% if they are considering storing that corn on-farm for a period of 4 months or more. Long-term storage requires lower moisture levels to prevent the grain from going out of condition due to molds or insects.
What is ideal corn moisture?
Harvest Loss: The optimum harvest moisture content for corn is approximately 23% to 25%. At this moisture level, kernels shell easily and stalks generally stand better, which can make harvesting more efficient. A normal harvest loss level of a timely and efficient harvest is about 1 to 2%.
What moisture is corn considered dry?
The standard moisture for corn is 15.5 percent, so when grain is delivered at greater than 15.5 percent grain moisture, the weight is adjusted down. (This reflects the remaining weight when the grain is dried to 15.5 percent moisture, losing water weight in the process.)
What moisture does corn black layer?
The kernel moisture content at black layer formation usually ranges from 25% to 40%, and averages around 30% moisture. Physiological maturity is greatly influenced by the relative maturity (RM) of the individual corn product. Short season products mature earlier than fuller season products.
How long will dried corn stalks last?
The Indian corn, just dry put in a dry place, they will be dry in a few weeks then store them in a sealed container. I have been using the same Indian Corn ears for years. The gourds will start to go bad in about 6 to 8 weeks, but you CAN shellac them to keep them indefinitely.
How long can you leave corn on the stalk?
Corn for fresh use: For fresh eating, corn should be cooked as soon after harvest as possible—within an hour or two for the best flavor. Don’t remove the husks until you are ready to cook. You can store unhusked corn in the refrigerator for up to a week. Most varieties will keep in the refrigerator for up to one week.
How do you test corn moisture?
The most accurate method of determining grain moisture content is the standard scale and oven-based test which uses published standardized procedures to dry a sample in a laboratory oven. The moisture content is then calculated using an equation based on the weight lost during the oven drying.
Is Phantom yield loss real?
“Phantom Yield Loss is exactly what it sounds like. It’s a yield hit that happens to corn when you don’t start harvest earlier. It occurs because you allow the crop to naturally dry down to a certain point before harvest. When it loses that much moisture in the field, it basically cannibalizes itself a little bit.”
How do you convert wet bushels to dry corn?
- If initial grain moisture is 20%, initial dry matter content is 80% (100 minus 20).
- If desired final moisture content is 15%, ending dry matter content is 85% (100 minus 15).
- Multiply weight of wet grain by initial percent of dry matter; then divide by desired ending percent dry matter.

Is dry corn heavier than wet corn?
Wetter grain obviously weighs more than drier grain and so grain buyers will “shrink” the weight of “wet” grain (greater than 15% moisture) to the equivalent weight of “dry” grain (15% moisture) and then divide that weight by 56 to calculate the market bushels of grain they will purchase from the grower.
How do you shrink moisture in corn?
- Example moisture shrink calculations: Assume we have 1,000 lb of 25.5% moisture corn, and we want to know how many bushels we would have at 15.5% final moisture:
- wet bushels = 1,000 lb ÷ 56 lb/bu = 17.9 wet bu.
- moisture shrink factor = 100 ÷ (100 – 15.5) = 100 ÷ 84.5 = 1.183% per point.
How much does a bushel of high moisture corn weight?
The United States Department of Agriculture established the standard test weight of a bushel of corn as 56 lbs/bu based on 15.5% moisture content.
Why does corn dry in the field?
Field drying of mature corn grain is influenced primarily by weather factors, especially temperature, humidity, and rainfall. Simply put, warmer temperatures and lower humidity encourage rapid field drying of corn grain.
What does Black Corn mean?
Black corn has jet black kernels with a slightly purplish hue. Black corn grows on stalks that reach up to 3 meters in height. … Black corn is chewy and starchy. It produces what is called an “old fashioned” sweetness, meaning that although it is sweet, it is not as sugary as modern varieties of yellow corn.
