Agri-Service, Inc.


Increase Your Yield With Fertilizer


Logan Agri-Service, Inc. offers a variety of fertilizer options and a team of crop specialists to help determine the best product for your needs.


From its dry fertilizer storage facility in Griggsville, a fleet of applicators applies dry nutrients with accuracy across thousands of acres annually. Prescription single product and two-product variable rate application is a mainstay of the operation.


The Griggsville facility stores more than 600 tons of liquid UAN, starter fertilizer, and ammonium thiosulfate. Liquid UAN is applied through row crop sprayers, primarily as a weed ‘n’ feed program with herbicides. Logan Ag has a liquid injection unit available for custom application.

With anhydrous ammonia storage facilities in Griggsville, Perry, and Scott County, Logan Ag is your “go to” dealer for ammonia during the busy fall and spring application seasons. Our increased storage capacity and larger pumping system enables us to promptly fill tanks for fast turnaround to the field. A fleet of more than 100 nurse trailers, rental tool bars, and delivery trucks makes Logan Ag THE reliable ammonia supplier in western Illinois.


Through a network of suppliers, Logan Ag sources dry and liquid fertilizer and anhydrous ammonia from terminals across the Midwest for direct shipment to farms. Delivery is available via Logan Ag trucks or common carriers. Contact us for more information. >


Use of phosphate enhancement products, nitrogen stabilizers, plant growth regulators, biologicals, and foliar micronutrients such as Logan AGRI-YIELD PREMIUM FOLIAR is highly recommended. These products help improve nutrient availability to the plant, increase early season plant growth and development, reduce crop stress, and improve yield.
