What Our Customers Say
Solu-Cal products have changed the way we work, especially with larger properties. The ability to apply one-quarter the amount of product and still deliver the results our customers expect saves us time & money in trips back to the truck. We are able to provide a better value and more efficient service to our customers. All of the Solu-Cal products have delivered superior results for us.

Peak Iron does make a difference. The customer used it in their hunting preserve. They plant in strips which makes it nice to see results. I have been using at home in the garden. There is definitely something to it. We have sold most of our inventory, which what I wanted to do. The Solu-Cal line will be a standard product in our inventory.
