putting up silage from an heirloom variety of corn for our cattle

We are putting up silage made from open pollinated white corn this year. The variety dates to the mid 19th century but has performed well. The stalks are extremely tall, and we've been impressed with the yield and quality. We understand that a lot of our customers want meat that is fed with non-GMO feeds, and this is a heritage plant that seems very viable for quality silage. We will try to post pictures of the process soon.
