Onion Storage

Onions Stored Right

Just like most row crops, growing onions can be a difficult challenge. There are so many variables to focus on in order to have a successful crop. When growers are digging in the field it’s quick to identify yields and onion quality, but preserving all this hard work comes with the next phase of challenges, storage. Growers want to be able to store their crop to stay fresh, for as long possible. By doing this, they are able to maximize their profits and set themselves up for years of growth. At Suberizer Inc., we learn what needs and goals growers have to help develop the proper solution for their success.

It all starts with a high-tech onion storage solution. Our solutions, in the big picture, are small investments for the farming career. Our onion storages and systems are some of the best in the business and can make a big impact on growers profits.


AirEverywhere Under-Floor Air Distribution System
The air requirements for onions is consistently rising.  A properly designed storage that carefully considers the function of the AirFloor can produce amazing output. This is especially effective for bulk storage. The Suberizer AirFloor can also work well for box, tote, or crate storage. This type of storage system works well for normal post-harvest storage as well as for temporary storage after packing and staging.
