How much water does it take to produce an ear of corn?

A high-yielding corn crop uses about 600,000 gallons of water per acre. An acre of corn releases approximately 4,000 gallons of water a day in evaporation. Corn uses nearly 3,000 gallons of water for each bushel of yield. Finally, it takes approximately 127 gallons of water to produce one pound of corn.

Why do farmers leave corn in the field?

Field corn, also sometimes called “cow corn,” stays in the fields until the ears dry because corn is very high in moisture and must be dry to be processed. That is why farmers leave stalks in the field until they are golden brown in the fall. … Some of that corn is saved to provide seed for the next season’s corn crop.

How do you dry out corn?

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%.

How dry should corn be?

24 hoursCorn should be dried to less than 15% moisture with 24 hours after harvest. High capacity, continuous flow driers are generally capable of rapidly drying corn to 15 percent moisture or less, but in-bin drying systems are generally not, and thus, present serious management challenges.

How do you measure moisture in corn?

To calculate the moisture content of a sample, divide the moisture weight removed in drying by the fresh weight of the sample, then multiply by 100 to get a percentage.

How long does it take to air dry corn?

four to eight weeksDrying time depends on initial grain moisture, airflow per bushel provided by the fan and weather. If you use the corn moistures and airflows recommended in Tables 1 and 2, drying usually takes four to eight weeks depending on the weather.

What is the highest USDA grade for vegetable products?

1 means good quality and is the chief grade for most fruits and vegetables.

What is dry corn moisture?

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.)

How do you price high-moisture corn?

“If the buyer and seller agree on this method of adjusting for the excess moisture, they can determine the value of the 1,000 pounds of high-moisture corn by multiplying the cash price per bushel of corn on that day by the equivalent bushels of 15.5% moisture corn in the load,” says Fanning.

How fast does field corn dry down?

Corn will normally dry approximately 3/4 to 1% per day during favorable drying weather (sunny and breezy) during the early warmer part of the harvest season from mid‑September through late September. By early to mid‑October, dry-down rates will usually drop to ½ to 3/4% per day.

How much does a bushel of corn weigh at 20 moisture?

100,000 lbs of grain at 20% moisture = 80,000 lbs of absolute dry matter (i.e., 100,000 x 0.80). 80,000 lbs of absolute dry matter = 94,118 lbs of grain at 15% moisture (i.e., 80,000 / 0.85). 94,118 lbs of grain at 15% moisture = 1681 bu of grain at 15% moisture (i.e., 94,118 / 56).

Will Corn Freeze Dry in field?

When temperatures drop in the 20s and below then corn will freeze and dry over the winter. … Often if corn is standing well, field losses can be low if it needs to stand into early winter.

How do you know when corn is dry?

If harvesting for popcorn, flour, flint, or dent corns, harvest when ears are dry. Kernels should be smooth, hard, and glossy. After harvesting, the ears can be dried in a covered area with good air circulation for a few more weeks to completely dry.
