Iowa Department of Agricultural: On Farm Fertilizer Storage

By | August 9, 2017

Iowa farmers must follow all laws and rules regarding secondary containment, loading and unloading of liquid and non-liquid bulk fertilizers and placement restrictions of Anhydrous Ammonia storage locations.  As a result, the following regulations apply:

Bulk Dry Fertilizers

  • Fertilizers can be offloaded directly onto the applicator in the field of application,
  • Bulk dry fertilizers must be stored in a totally enclosed building; loading of the fertilizer into the applicator or a tender truck must take place within the building.
  • If the loading/unloading of dry fertilizer does not take place in one of the locations listed above, then  an approved load pad is required that meets the specifications of the Iowa Administrative code 21-44.57(2).
