Potassium Sulfate fertilizer is 100% water-soluble Potash fertilizer. Potassium is one of three main nutrients (Nitrogen (N), Phosphorus (P), and Potassium (K)) required for growing healthy plants. Potassium has many benefits including:

  1. It enhances roots growth in plants.
  2. It improves the yield and quality of plants.
  3. It balances plants’ metabolism to improve protein synthesis to energize plants for healthy growth.
  4. It improves the immune system in plants so they become more resistant to diseases.

In addition, Potassium Sulfate contains 18% Sulfur, which is very important in the growth process for plants and to adjust the pH level of your soil or hydroponics systems.

Potassium Sulfate Fertilizer Application Rate

Hydroponics: Mix at a rate of 2-3 tablespoons per gallon of water

Foliar: Mix at a rate of 2-3 tablespoons per gallon of water

Soil: Apply 2 pounds per 100 sq.ft.

Dissolves rapidly with high dissolution rate compared to other SOP products. At 20掳C, a typical quantity of 100kg per 1000 liter of water will dissolve in a few minutes to yield a clear 10% solution, with virtually no insoluble residues.

Ideal for salt-sensitive crops, it contains very low levels of chloride, which makes it an ideal fertilizer for crops that are sensitive to this detrimental element. With its very low salt index (46 in index), it is a recommended source of potassium where there is a risk of salinity build-up and in intensive cultivation systems, both protected and in open field.

High sulfur content (18% S) is the fertilizer of choice for plants with high sulfur requirements, such as oilseed rape, sunflower, cabbage, onion, leek, and others. This fertilizer decreases the pH in the stock solution.

Provides nitrogen-free potassium, which allows growers to schedule fertilization programs that match crop needs during stages of reduced nitrogen requirements.


1. How often should I apply Potassium Sulfate fertilizer?

It is recommended to apply Potassium Sulfate fertilizer every 4-6 weeks during the growing season.

2. Can I use Potassium Sulfate fertilizer for all types of plants?

Yes, Potassium Sulfate fertilizer can be used for a wide range of plants including vegetables, fruits, flowers, and trees.

3. Is Potassium Sulfate fertilizer safe for the environment?

Yes, Potassium Sulfate fertilizer is safe for the environment when used according to the recommended application rates.


Potassium Sulfate fertilizer is an essential nutrient for healthy plant growth. It enhances roots growth, improves yield and quality, balances plants’ metabolism, and improves the immune system in plants. With its high solubility and low salt index, it is an ideal fertilizer for salt-sensitive crops. Its high sulfur content makes it suitable for plants with high sulfur requirements. By providing nitrogen-free potassium, it allows growers to tailor fertilization programs to match crop needs. Overall, Potassium Sulfate fertilizer is a valuable addition to any gardening or farming routine.
