- Optifert is a highly soluble acidic compound fertilizer (pH 2) formulated for date palm nutrition under calcareous and alkaline conditions. It supplies a balanced ratio of nitrogen, phosphorus and potassium (NPK 15-17-27) that supports every growth stage, from flowering to full fruit ripening. It improves fruit set, increases fruit size and sugar content, protects irrigation systems from scale deposits and ensures optimal nutrient uptake.
Key Features:
- Balanced nutrient formula that supports growth and fruiting.
- High potassium content to improve fruit quality and raise sugar levels.
- Acidic nature prevents clogging of irrigation networks and dissolves calcium salts.
- Enhances micronutrient uptake with high efficiency.
- Increases yield while maintaining marketable fruit quality.
- Suitable for all modern irrigation systems.
- Fast dissolving and easy to use.
- Safe for plants when used at the recommended rates.
