Fertilizer Services


 Some producers cross the liquid fertilizer storage capacity threshold set by the Department of Agriculture. Effective July 1, 2007 farmers can store up to 6,000 gallons of bulk liquid fertilizer on their own property without having a permit or secondary containment.

Agricultural commodity producers who store greater than 6,000 gallons of bulk liquid fertilizer, or who store fertilizer for distribution must have proper containment that is permitted by the Minnesota Department of Agriculture (MDA). This containment usually consists of concrete, metal, or synthetic lined earth, metal, wood, or concrete. The MDA does not recommend earthen clay liners due to a history of failure in Minnesota when the liners are not properly constructed and maintained.

The capacity of the containment area (dike) should be 125% of the largest tank plus the displacement of other tanks stored inside the dike.
