FlowSOP
Precision. Purity. Performance.
FlowSOP is Exzeler’s premium-grade water-soluble potassium sulfate (SOP) fertilizer, formulated for modern agriculture where chloride-sensitive crops and sustainable yields matter most. With 50% K₂O and 45% SO₃, FlowSOP delivers a dual nutrient punch that fuels growth and fortifies plants against abiotic stresses, from drought to salinity.
Free from chloride and sodium, FlowSOP is your go-to solution when high-quality potassium and sulfur nutrition is essential for fruit quality, shelf life, and stress resistance. Whether in greenhouses or open fields, FlowSOP guarantees solubility, compatibility, and consistent performance.
Key Benefits
- Chloride-Free Formula: Ideal for sensitive crops like vegetables, fruits, and flowers.
- High Solubility: Dissolves rapidly in water (> 110 g/L at 20 °C), ensuring easy integration into fertigation and foliar systems.
- Low Salt Index: Safe for young seedlings and salinity-sensitive environments.
- Boosts Quality: Enhances fruit color, taste, firmness, and storability.
- Resilience Enhancer: Improves tolerance to drought, salinity, and temperature extremes.
Application Guidelines
Fertigation
FlowSOP is suitable for all irrigation systems, including drip, pivot, and sprinkler systems. Recommended rates:
- Standard application: 15–25 kg/ha per session.
- Closed-loop systems: Continuous feed with 0.01–0.1% solution concentration.
- For season-long fertigation, adjust the dose based on crop development stages and soil/tissue analysis.
Note: Do not mix FlowSOP with calcium-containing products (e.g., calcium nitrate) in the same tank. Use separate tanks or schedule sequential applications.
Foliar Application
FlowSOP provides fast-acting relief for potassium and sulfur deficiencies:
- Recommended concentration: 0.5–2 % depending on crop type and growth stage.
- Apply during early vegetative and mid-generative phases for optimal uptake and impact.
- Always pre-test on a small area to confirm leaf tolerance.
Compatibility & Handling
FlowSOP is compatible with most fertilizers and crop protection products, except those containing calcium. Perform a jar test prior to mixing:
- Check for sedimentation, foaming, or flocculation.
- Mix in soft or clean water for optimal results.
- For complex blends, use separate mixing tanks or injectors.
Handling and Storage
- Storage: Keep in a cool, dry, and well-ventilated place. Avoid exposure to moisture.
- Packaging: Available in moisture-resistant bags with inner lining for long shelf life.
- Shelf Life: Up to 2 years under optimal storage conditions.
Recommended Crops
Ideal for high-value crops including:
- Tomatoes, cucumbers, melons
- Citrus, grapes, berries
