# Potassium Sulfate Fertilizer 0-0-53

### **Potassium Sulfate Fertilizer 0-0-53**

Maximize your crop's quality and yield with **Potassium Sulfate Fertilizer 0-0-53**, a solution-grade, 100% water-soluble potassium fertilizer (K₂SO₄). Delivering a powerful combination of 53% soluble potash (K₂O) and 17% sulfur in a single crystalline form, it stands as one of the most concentrated chloride-free potassium sources available on the market.

Potassium is a vital nutrient that regulates water movement, enzyme activity, and sugar transport into developing fruit. The result? Noticeable improvements in fruit size, vibrant color, firmness, and post-harvest storage quality.

**Ideal For:**

-   **Chloride-Sensitive Crops:** Perfectly suited for quality-sensitive plants like tomatoes, peppers, berries, grapes, potatoes, citrus, and tobacco.
    
-   **Hydroponics & Fertigation:** An excellent choice for recirculating hydroponic systems where chloride accumulation would otherwise become a problem.
    
-   **Versatile Application:** Dissolves completely and cleanly for use in soil, foliar spraying, fertigation, and hydroponic setups.
    

**Key Features & Benefits:**

-   **High-Potency Potassium (53% K₂O):** Drives robust fruit development and overall plant health.
    
-   **Plant-Available Sulfur (17%):** Supplied as easily absorbed sulfate, supporting essential amino acid synthesis without the need for a separate amendment.
    
-   **Chloride-Free Chemistry:** Exceptionally safe for sensitive crops and enclosed watering systems.
    
-   **Tested & Certified:** CDFA registered and rigorously third-party lab-tested for heavy metals, with results consistently well below required limits.
    

**Important Handling & Application Rules:**

-   **Crucial Mixing Rule:** Always keep this fertilizer in Tank B, completely separated from calcium-containing fertilizers. Combining them in a concentrated stock solution will cause precipitation.
    
-   **Dissolving Tip:** For best results, pre-dissolve the crystals in warm water before injecting them into your system.
    
-   **Foliar Spraying:** To avoid leaf burn, apply foliar sprays only in the early morning or late afternoon, and ensure your concentrations are kept modest.
