Out in the Cornfield

Things are looking up in the corn field, now that we have had rain. 
Denting has begun, which is part of the maturation process. Most of the cobs are filled to the tip, which is what we hope for.  
 The cob above is not filled to the tip, that is from lack of moisture, I assume.  
 It's not a perfect picture in the corn fields.
In another field, the cobs are beginning to tip, also a step toward maturation in many varieties. 
There is some damage from birds and wild life. 
When a corn plant begins to turn brown from the bottom, it is called firing. It is a sign of stress from lack of water or nutrients. The plant sacrifices itself to send nutrition to the cob. 
Considering the Summer rain total, the corn is in pretty good shape. 
Much of the corn is nine feet tall. 
 The rain that we received over the weekend is in time to positively impact this corn crop. 
When a cob dries from lack of moisture, rather than maturity, it produces lighter test weight, lower quality kernels. 
In most areas of the fields, the cobs are still taking nutrition from the plant. This process will continue to until the plants fully mature, when the cob forms a black layer between itself and the kernels.
As they mature, many cobs will tip down, with the brown silk pointed toward the ground like a tail. 
As always, we won't have a corn crop until the grain is out of the field, but today things are looking pretty good in the corn fields of GriggsDakota.
