Keep your plants happy, healthy, and hydrated with our high-quality Sulfate of Potash (SOP). Potassium sulfate, also known as sulfate of potash, is a naturally occurring combination of sulfate and salt of potassium ions. This nutrient is essential for successfully and efficiently moving water throughout plants.

Rocky Mountain BioAg® offers the highest quality from Diamond K, so you know you're getting the best of the best. In addition, the 50-pound bag is listed by the Organic Materials Review Institute (OMRI) for use in organic crop production.

In nature, potassium is found as a nutrient within salts such as potassium chloride and potassium sulfate. Although plants use sulfur and chlorine, chlorine doesn't typically contribute to soil health. Potassium sulfate provides sulfur in a form that plants can utilize, which helps naturally decrease the pH of the soil.

Our Sulfate of Potash is ultra-finely ground, allowing it to be used in dissolution equipment and with SOP-based solutions and suspensions. Rocky Mountain BioAg® offers our Sulfate of Potash in several sizes to best accommodate your needs. So, whether you're a backyard gardener or an agricultural operation with thousands of acres, we've got you covered.

I have a greenhouse that unfortunately does not get the ideal sunlight due to its location on the north side of my home. I have been using Rocky Mountain BioAg’s Quantum Growth Organic Total for over a year and have seen a dramatic increase in plant growth and vegetable yield compared to past years. Highly recommend the product.
