Marion Ag Service and ADM partner to expand access to Poly 4 fertilizer

Marion Ag Service has entered into an agreement with Archer Daniels Midland, an agricultural origination and processing company, to warehouse and distribute Poly 4, a multi-nutrient fertilizer mined and manufactured by Anglo American and represented in the market by ADM.

The strategic partnership is designed to enhance regional availability of Poly 4, supporting key cropping systems across the Pacific Northwest.

Under the agreement, Marion Ag Service will warehouse and transload Poly 4, enabling efficient access for agricultural retailers throughout the region. This initiative aims to strengthen supply chain capabilities and ensure timely delivery to growers seeking innovative nutrient solutions.

Poly 4 is a naturally occurring mineral fertilizer that delivers four nutrients — potassium, sulfur, magnesium and calcium — from a single source. Its unique composition and gradual nutrient release make it a versatile tool for agronomic programs.

“The combination and form of nutrients in Poly 4 provide agronomic retailers like us with a powerful solution to help growers incrementally improve their outcomes,” said Jeff Freeman, director of sales and marketing at Marion Ag Service.
