SUL4R-Plus
SUL4R-Plus BZ
Secondary nutrients support critical metabolic and biochemical processes a crop requires to maximize yield potential.
There’s nothing “secondary” about secondary nutrients. That’s why we put them first. Every SUL4R-PLUS product starts with the same two vital nutrients — calcium and sulfur — that fuel growth, improve soil health and support key metabolic processes. This consistent nutrient base provides the flexibility to meet a wide range of crop and soil needs.
When it comes to calcium sulfate fertilizer, we’re in a class all our own. See the distinct advantages our products have over others.

SUL4R-PLUS is a great product. It works well, it’s not one of those flashy new type products where you’re trying to grasp something that isn’t there. What SUL4R-PLUS says it is, it is, and it does what its supposed to do.
—ANDY SCHAFSTALL, PREMIERAG
For pound-per-pound availability throughout the season, SUL4R-PLUS is definitely the go-to product as far as cost effectiveness in poundage of sulfur. Tremendous return on investment.
—CHRIS JONES, JONES FARMS
I like that SUL4R-PLUS is a calcium sulfate so it doesn’t effect your pH as much as AMS does. SUL4R-PLUS is also consistent — the spread pattern is good and it blends well.
