How do you calculate moisture in corn?

Moisture Shrink

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 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 moisture discount level for corn?

15.5%
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 content in a dry weight basis?

The amount of water is determined by subtracting the dry weight from the initial weight, and the moisture content is then calculated as the amount of water divided by the dry weight or total weight, depending on the reporting method.

What is a good test weight for corn?

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.

Why do farmers let corn dry out?

When corn is mature in the field it has approximately 30% moisture (water). Farmers let corn dry in the field for as long as possible and will ideally harvest when the moisture level is 23 to 25% or lower. At this moisture level, kernels shell easily and stalks generally stand better making harvest more efficient.

How much does a bushel of high moisture corn weight?

56 pounds
The industry standard moisture content is 15.5%, and the weight per bushel is 56 pounds.

What is the best moisture to harvest corn at?

approximately 23% to 25%
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 is moisture content formula?

Calculate the moisture content on a wet-weight basis using the following formula: Moisture content (%) = W2 – W3 x 100. W2-W1. where, W1 = weight of container with lid; W2 = weight of container with lid and sample before drying; and W3 = weight of container with lid and sample after drying.

What is DB in moisture content?

Dry basis moisture content (designated Md in the text) is described by the percentage equivalent of the ratio of the weight of water (WW) to the weight of the dry matter (Wd).

How do I get a high weight corn test?

Corn at higher moisture contents and cold temperatures likely will have more mechanical damage. Corn dried at lower temperatures in a dryer with mixing in the dryer column generally will have a higher test weight. Grain dried at temperatures in excess of 180 degrees generally will have less increase in test weight.

Does test weight matter in corn?

“The pounds of grain in a bin will be affected by test weight, but the pounds of grain harvested per acre are not affected by test weight.” Test weight is a density measurement that is used as an indication of grain quality but is not a factor in determining grain yield in bushels per acre.

How is the weight of corn converted to moisture?

Shelled corn figures apply at any time. Divide total grain weight by appropriate standard bushel weight. Divide total grain weight by 100. Table 4. Moisture conversion for soybeans. Table 5. Moisture conversion for wheat. Table 6. Moisture conversion for grain sorghum.

How to calculate grain weight shrinkage in corn due to?

Thus, if 1,000 lb. of 25% moisture corn were dried to 15.5% moisture, the total weight loss due to water and dry matter removal would be 117.4 lb. (1,000 multiplied by 0.1174). The resulting weight of the dried grain would equal 882.6 lb. (1,000 minus 117.4) using this shrink method.

How much weight is lost when corn is dried?

When shelled corn is dried from 25% to 15.5% total weight reduction is 11.24% of the original weight. When handling loss is added the total weight reduction would be greater than 11.24%.

How long is 15.5% corn good for?

Corn at 15.5% can be stored up to six months, 14% up to 12 months and 13% for more than one year. Total weight loss while drying grain to desirable moisture levels is called ‘shrink’ and grain buyers usually take this into consideration to estimate how much actual grain they will have after it is dried down.
