I am not sure where "here" is, but I will offer some insight to what has been said above.
Ditto on sweet corn v. field corn.
Now, field corn comes in 1,000 varieties and most is 105-118 day growing season (at least here in the midwest.)
Field corn is rated on moisture content. For the farmer to take it to the elevator, it must have at most 15% moisture content or the elevator will dock the price of the grain. Anything below 15% and the farmer loses money on weight.
For example, this is why you see corn in the fields until late fall. This is also why farmers that can afford them buy grain bins with dryers.
Having said the above, it costs money and time to dry grain. A good rule of thumb is for every percent of moisture per bushel it costs .02 gallons of lb, 2-5 cents of electricity, and handling and transportation to the elevator costs 5-8 cents a bushel. Basically it is 4-8 cents per water % per bushel to dry corn.
You have to figure what is is going to cost you to dry it and then find out what the docking fee is per percentage.
I doubt the corn is ready for harvest yet. If it is already brown, it is in poor shape, which in that case it might be used for silage.
The bottom line is that is why you see corn in the fields after it is ready to harvest. Sometimes LONG after it is ready to harvest. The farmers test the corn and it is cheaper to let nature dry it down to 15-15.5%.
Beans are another story. While moisture content is also a factor, the bean pod will lose the beans. If a farm has corn that is ready, and beans that are ready at the same time, he will leave the corn and harvest all the beans, and only then get back to harvesting corn.
Also, farmers mix 13% corn with corn that is higher than 15% to get the entire bin to the right level.
“A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves…freely, his sly whispers…heard in the very halls of government itself. For the traitor appears not a traitor; he speaks in accents familiar to his victims...he infects the body politic so that it can no longer resist. A murderer is less to fear.” Cicero
