Fertilizer Storage for Extended Shelf Life

There are two main types of fertilizer: granular (sometimes called dry) and liquid. Granular fertilizer is any kind of fertilizer material that is distributed in non-liquid form. While granular and liquid fertilizers have similar chemical consistencies, they have various strengths and weakness, including storage.

Granular fertilizer can be easier to store than liquid fertilizer. Under the right storage conditions, it has an indefinite shelf life. Liquid fertilizer, on the other hand, can lose strength over time and therefore tends to have a shorter shelf-life (roughly 8-10 years).

This article will focus on storage suggestions for dry fertilizer because we develop dust suppression products for granular fertilizer. Read on for ways to create the ideal storage conditions to maximize the shelf life of granular fertilizer.

Storage for Extended Shelf Life

  • Store granular fertilizers in an enclosed shelter, away from other chemicals. Fertilizer attracts moisture and, over time, will clump up if it is not sealed and dry.
  • Store fertilizer in their original container unless damaged. Containers should be checked for damage regularly. If damage is detected, repackage and relabel the contents of the container or place the damaged container in secondary containment.
  • Use pallets and shelves to keep fertilizer containers off the floor.
  • Be sure to separate dry fertilizer from other liquids. Consider using spill containment tools to prevent liquid spills from spreading.

Rules And Regulations

Some farmers want on-farm storage to help control costs. Before moving forward on on-farm storage, make sure to check the rules and regulations for your state. This article from AgWeb discusses some of the regulations you might encounter when storing liquid or dry fertilizer.

Considerations for Building or Modifying a Storage Facility

Blackland Research & Extension Center published this article about fertilizer storage and handling. It contains information about how to manage fertilizer safely. As written in the article, building or modifying a storage facility can be expensive, but not as expensive as a major accident or lawsuit.
