Video: Evaluating corn silage processing in the field (Jon Rasmussen)

By Jon Rasmussen, Vita Plus technology specialist
Trying to get a handle on corn silage processing while the choppers are moving has gained a great deal of interest in the recent years. A few considerations can help make the evaluation a little less subjective.

Start by gathering a fresh corn silage sample in a 32-ounce container (a large soda cup works well). Note: A consistent sample size is extremely important.

After gathering the sample, decide how to separate and count the number of whole kernels. The video below shows the use of a Penn State shaker box to not only separate the kernels, but also get a measure of particle size.

Other methods may be to simply sort out the kernels or float them in water.

No matter your preference, the following results will indicate your potential corn silage processing:

• 0-2 kernels found:  Sample is likely well processed
• 3-6 kernels found:  Sample may be adequately processed
• 6 or more kernels found:  Re-evaluate the processing at the chopper

Enjoy the video and good luck processing your corn silage.  Best wishes for a good and safe harvest!
