Calcium and potassium Nitrate Fertilizer
Haifa Soluble DUO offers a range of calcium-potassium fertilizers. Carefully balancing these two essential nutrients, Haifa Soluble DUO enhances sugar content, improves color, and extends the shelf life of fruit yields.
Made of top-quality raw materials, Haifa Soluble DUO formulas offer both convenience and performance. Ideal for situations where a combination of potassium and calcium is required while keeping low nitrogen rates, Haifa Soluble DUO is perfectly suited for Nutrigation™ (fertigation) and foliar applications.
Advantages of Haifa Soluble DUO
- Ammonium-free: Ideally suited for fruit development and growth.
- Low nitrogen-calcium ratio: Allows optimal calcium management when nitrogen needs to be limited.
- Highly concentrated: Delivers readily available potassium and calcium.
- Fully water-soluble: Perfect for Nutrigation™ and foliar use.
- Extended shelf-life: More stable and easier to handle compared to typical calcium fertilizers.

Free-flowing, user-friendly
Haifa Soluble DUO ensures excellent stability, even in humid conditions — a common challenge for calcium fertilizers. This guarantees the product stays dry, non-compacted, and ready to use at any time.
Multi-K™ inside
The potassium in Haifa Soluble Duo formulas comes from Multi-K™ potassium nitrate, the purest and most efficient source. The nitrate provides a controlled portion of nitrogen, ensuring the right balance without overloading during critical growth stages.
