What is the moisture discount level for corn?

What is the moisture discount level for corn?

For proper storage, grain moisture content has to be reduced to acceptable levels. Corn at 15.5% can be stored up to six months, 14% up to 12 months and 13% for more than one year.

How do you calculate 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. standard bushels = 17.9 x [(100 – 11.83) ÷ 100] = 17.9 x 0.8817 = 15.8 std bu.

How do you adjust corn yield for moisture?

If the desired ending grain moisture content is 15% (the typical market standard), then the desired ending percent dry matter content is 85% (100% – 15%). Multiply the weight of the “wet” grain by the initial percent dry matter content, then divide the result by the desired ending percent dry matter content.

What is the USDA standard moisture for corn?

adjusted for the applicable moisture shrink factor, according to Exhibit 12, to reflect the quantity at the 2-LP standard moisture level. Example: Grain sorghum is 14.0 percent and corn is 15.5 percent.

Why do farmers let corn dry out?

The fresher the corn, the more sweet it will taste. 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.

What is a good moisture for corn?

around 23 to 25%
The optimum harvest moisture content for corn is around 23 to 25%. At this moisture content range, kernels generally shell from the cob easily.

What is a good test weight for corn?

56 lbs/bu
The official minimum allowable test weight in the U.S. for No. 1 yellow corn is 56 lbs/bu and for No. 2 yellow corn is 54 lbs/bu (USDA-AMS (FGIS), 1996). Corn grain in the U.S. is marketed on the basis of a 56-lb “bushel” regardless of test weight.

What is the best moisture to harvest corn?

The optimum harvest moisture content for corn is around 23 to 25%. At this moisture content range, kernels generally shell from the cob easily. During harvest time, kernel moisture content loss averages about 1 to 2%/day.

How do you convert wet bushels to dry corn?

Follow these steps:

  1. If initial grain moisture is 20%, initial dry matter content is 80% (100 minus 20).
  2. If desired final moisture content is 15%, ending dry matter content is 85% (100 minus 15).
  3. Multiply weight of wet grain by initial percent of dry matter; then divide by desired ending percent dry matter.

What happens if you dont Detassel corn?

Up to 70% of tassels are removed mechanically. Then crews come through and clean the fields by hand removing any tassels that the machines missed. Timing is important because if you detassel too early yield may decrease. If you wait too long, the corn plant will start to pollinate itself.

What do farmers do with dead corn stalks?

There are two primary uses of leftover residue for livestock benefit: grazing cattle on the leftover residue and baling the residue for bedding. Grazing cattle on the residue helps prolong feeding hay to the cattle.
