- Optifert 16-35-10 +TE is an acidic fertiliser designed to improve soil conditions, ideal where irrigation water is hard and calcium bicarbonate levels are high. Its balanced formula, rich in trace elements, promotes crop health, increases yield and improves fruit quality.
Key Features
- Rich in phosphorus (35%) to promote root growth and flower development.
- High nitrogen content (16%) to support vegetative growth.
- Moderate potassium content (10%) to improve fruit quality.
- Added trace elements – copper, iron, manganese and zinc – to help plants withstand environmental stress.
Specifications
- Composition: Nitrogen (N) 16%, Phosphorus (P₂O₅) 35%, Potassium (K₂O) 10%, pH 2
- Trace elements: Copper 50 ppm, Iron 250 ppm, Manganese 125 ppm, Zinc 170 ppm
- Net weight: 25 kg
- Use: Suitable for a wide range of crops and well suited to alkaline soil conditions
Directions for Use
- Fertigation through drip irrigation:
- Early growth stage: 0.5–0.8 g per litre of water (50–80 ppm).
- Flowering stage: 0.8–2 g per litre of water (80–200 ppm).
- Application by spraying:
- 7–10 kg per hectare depending on plant type, growth stage and planting density.
- Foliar feeding:
- Suitable for foliar use where soil alkalinity is high or calcium bicarbonate is present, at 2–4 kg per 1,000 litres of water (0.2–0.8% concentration).
Notes
- Test on a small part of the crop before full application to confirm suitability.
- Avoid spraying during very hot periods to prevent leaf burn.
- Can be mixed with other fertilisers except those containing calcium.
