Growing Together

Marion Ag has been finding ways to help growers and resellers grow their business for over 50 years.

Today our business is focused on three core disciplines; Technical Services, Soil Health, and Nutrient Delivery.

Technical Services

Marion Ag prides itself on the character and aptitude of its employees.  Our team’s expertise is broad and varied.  This expertise allows for a number of our services to stand alone on a for-fee or contract basis.

Soil Health

Soil Health is the foundation for optimum agricultural and horticultural production. Marion Ag can help evaluate and manage the key components of soil health.

Nutrient Delivery Professionals

From the mine or manufacture to the field; it takes knowledgeable, experienced and trusted professionals to deliver results.  Our team at Marion Ag strives to deliver products and services right the first time.

Over the years, we have expanded our roots far beyond our home in St. Paul, Oregon and adapted our products to satisfy the needs of our ever-expanding customer base.
