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 1250 ton dry fertilizer storage facility in Griggsville, a fleet of dry spinner spreaders applies dry products with precision across thousands of acres annually.  Single product and two-product variable rate application is available.


The Griggsville facility stores more than 600 tons of liquid UAN and starter fertilizer.

Liquid UAN product is applied through row crop sprayers, primarily as a weed ‘n’ feed

with herbicides.  Logan Ag has a liquid injection unit available for custom application or rent.

With anhydrous ammonia storage facilities at both Griggsville and Perry, Logan Ag is your “go to” dealer for ammonia during the busy spring and fall application seasons.  Our increased storage capacity and larger pumping system enables us to promptly fill empty tanks for fast turnaround to the field.


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


We recommend use of phosphate enhancement products, urease inhibitors, and nitrification inhibitors, as well as foliar micronutrients for increased nutrient availability and yield.  Find helpful information about each of these in the documents below.
