SERGEANT BLUFF, Iowa (AP) – Production is expected to resume in a few days at a northwest Iowa fertilizer plant that was damaged by a fire and subsequent explosion. The fire began around 6 p.m. Saturday at the Nulex plant in the Port Neal industrial area south of Sioux City. No injuries have been reported.

Nulex spokesman Jason Glover told the Sioux City Journal on Sunday that the fire was in a storage building and not in the main production facility. Glover says that means employees likely will be able to resume work in a few days.  The company produces liquid zinc micronutrients that are mixed with liquid fertilizers.

The Iowa State Fire Marshal Division and Iowa Department of Natural Resources are investigating the fire and blast.
