Twelve years ago, when Connor Agriscience introduced oxygen barrier film to the western US, we knew that if we could keep oxygen out of piles and bunkers, we could save more silage from the top three feet. It would be of better feed quality, and farmers could save and reclaim the investment they made in growing or purchasing the crop. We also knew that a “perfect crop” would be harvested at the right dry matter, chopped at the correct length, delivered to the pile or bunker in a reasonable pace, spread in six-inch layers, and packed nearly solid with correct tractor weight and pattern.

We also knew (and know today) that this kind of perfection is rare. Using the methods we teach and the tools we offer can help give a less than perfect harvest a better outcome. Sealpro® Silage Barrier Film is one of those tools.
