Sulfur Fertilizers and Sulfate Minerals
Shop elemental sulfur, sulfate of potash and sulfate minerals that supply sulfur along with potassium, iron, zinc, manganese or other nutrients.
How to Choose
These products serve different purposes and are not interchangeable. Use soil or tissue testing to identify the nutrient need and follow the label rate; elemental sulfur can affect pH while sulfate nutrients act differently.
Compare sulfur and magnesium products, trace minerals and products for high soil pH.
