COVID-19 Response 

The health and well-being of our employees and customers is very important to us. In an effort to practice social distancing and do our part prevent the unnecessary spread of the virus we will be limiting our close-contact interaction with our customers until further notice. Our front door will be locked at both our Gayville and Spink locations but our business will still be operating and preparing for our spring season. If you need anything, we ask that you call the appropriate office from outside during business hours and one of Valley Ag Supply’s employees will be out to assist you (take a hay test, purchase pet food, pay a bill, etc.). This also means no coffee in our office, but we’ll bring a cup out to your vehicle! We appreciate your understanding.

Due to the corona virus, we have cancelled our annual grower meeting. However, we will be coming out with an online version of our meeting so that you can still learn and have a chance at winning prizes.   


We are currently taking applications for truck drivers and an applicator for both our Gayville and Spink location. If you or someone you know is interested in either of these positions, please stop by our office or call Jimmy.


We work hard to find out what products will work best for you. Check out the data for yourself here or ask one of our agronomist to find out what will work best on your farm. 


Hay Stacks are our informative newsletters with up-to-date information on what is currently happening in the farming area.
