There are 2 ways to get it.

Through your local dealer

We have Riomax® dealers across North America who would be happy to service you and get you the product you need.

Find Your Closest Dealer Below

Directly from us

We do not have 100% dealer coverage so we are well-versed and absolutely ship orders of 10 ton (12 ton for Canada) or more directly to your ranch. (P.S. All orders ship free!)

Check out the details below

The Dealer locator.

Just enter your zip code and browse your closest dealers (as the crow flies.) You can head to them directly or give us a call. We don't have 100% coverage and some dealers may service larger areas than others, so we'd be sure to get you set up with the best option!

Note: Please give the dealership a call before heading there to ensure they will be around and have what you need in stock.

WE ALSO CAN SHIP DIRECT FOR FREE to your ranch on orders of 10 ton or more!

Direct Shipping details

Reach out to us and we'd be more than happy to talk through the best deal for getting the product to your ranch. We can direct ship orders of 10 tons or more directly to your ranch (not to mention the 8% quantity discount that goes along with that!) If 10 tons sounds like too much to start with, many of our smaller producers will group buy with their neighbors. Let's get wheels under it!

"We've been able to save enough hay with Riomax and we're increasing our production with Rhyzogreen. Both of those products have made it possible for us to have the confidence in knowing we're gonna be just fine.

"I think it's a pretty cheap way to get way more out of your soil than what we do weithout. More out of what they eat, so they eat less, and Rhyzogreen gives them more grass."

"...It's a win-win. You're attacking it on both fronts and you're nailing it on both fronts, so it's kind of a no-brainer. Why wouldn't you do both (Riomax and Rhyzogreen) at the same time?"
