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.
Why do farmers let corn dry out?
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.
Is corn dry when harvested?
Many growers will begin harvesting their corn grain when the moisture levels are about 20 to 25 percent. This way when they finish harvest in a few weeks, some of the corn will have naturally dried closer to the ideal moisture of 15 percent.
How do you harvest dry corn?
Harvest the ears on the next dry day and before the first frost. Pull each ear from the plants, pile the ears in a large basket and carry the basket into your garage or other sheltered area. Pull back the husks of each ear to expose the kernels. Use the husks to braid three or four ears together in a bunch.
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.
Why do farmers cut corn at night?
“We like to do it at night because the corn is cooler at night,” Dan said. “It takes less effort to get the heat out of the corn at night. If we harvest during the day, it’s way too hot and the corn goes into a starch.” After harvest, the corn is kept cool at the packing shed and is quickly sorted and boxed up on ice.
Can corn be too dry?
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. … Losses caused by difficulty in threshing the grain often occur when the corn is either too wet (grain moisture above 26% or too dry (grain moisture below 12% moisture).
How much does corn shrink when drying?
For instance, the shrink factor when drying corn to 15.5% moisture is 1.1834. Therefore, the moisture shrink when drying corn from 25.5% to 15.5% is 10 X 1.1834 = 11.83% (11.83% loss in grain weight due to the water removed during the drying of 25.5% moisture corn to 15.5% moisture.)
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.
