Product Introduction
EDTA NiNa2 is an efficient EDTA chelated nickel fertilizer. Product is a light blue powder, chelated nickel content ≥12.5%, pH (1% solution) 6.0-7.5, water-insoluble matter ≤0.1%. Using EDTA chelation process, nickel exists in EDTA chelated form, directly absorbable by crops, with absorption rate much higher than ordinary inorganic nickel fertilizers.

Application Reference
Drip Irrigation Application
Fully water-soluble formula, especially suitable for facility agriculture and precision fertilization, EDTA chelated nickel can be directly absorbed by crops.
- Concentration: 0.5—2 g/L irrigation water
- Application rate: 0.5—2 kg/mu/time
- Frequency: every 10–15 days
Foliar Spray Application
Rapidly supplement nickel and correct nickel deficiency symptoms.
- Dilution Ratio: 1:1000—1:2000
- Application rate: 30—60 L/mu
- Time: morning or evening, avoid high temperatures
Flush Application
Apply through irrigation to supplement nickel.
- Dosage: 1—3 kg/mu/application
- Dilution ratio: 1:100—1:200
- Timing: Key growth stages of crops
Water-soluble fertilizer compounding
Used as a nickel source in combination with water-soluble macroelement fertilizers for balanced nutrition.
- Use with water-soluble NPK fertilizer
- Addition ratio: 1–5%
- Suitable for melons, vegetables, and fruit trees
Suitable crops and recommended dosage
| Crop Type | Representative Crops | Drip Irrigation Dosage | Foliar Spray Dosage | Application Period |
|---|---|---|---|---|
| Fruit trees | Apple, pear, peach, grape, citrus | 1 — 2 kg/mu | 1000 – 2000 times dilution | Budding, flowering, and young fruit stages |
| Vegetables | Tomato, cucumber, pepper, eggplant, leafy vegetables | 0.5 — 1.5 kg/mu | 1000–1500 times dilution | Seedling, flowering, and fruiting stages |
| Field Crops | Wheat, corn, rice, soybeans | 5 – 1 kg/mu | 1000–1500 times dilution | Tillering stage, jointing stage |
| Cash Crops | Tea, tobacco, cotton | 1 — 2 kg/mu | 1000 – 2000 times dilution | Vigorous Growth Period |
- Store in a cool, dry place away from direct sunlight; use promptly after opening.
- When applying foliar spray, it is recommended to conduct a small-scale test first to confirm no phytotoxicity before large-scale use.
- Can be mixed with most fertilizers and pesticides, but a small-scale test is recommended before use.
- Filter the solution before drip irrigation to prevent nozzle clogging.
- Nickel dosage should be controlled to avoid excess.
FAQ
Typical symptoms of nickel deficiency in crops include:
- Leaf ChlorosisInterveinal chlorosis on new leaves
- Stunted growthSlow plant growth
- Leaf Tip NecrosisNecrotic spots on leaf tips
- Common Nickel SaltExists in inorganic salt form, requiring crops to convert it into absorbable forms, resulting in low absorption rate.
- EDTA Chelated NickelExists in EDTA chelated form, nickel is "wrapped" by EDTA molecules, good stability, not easily fixed by soil, crops can directly absorb, absorption rate far higher than ordinary inorganic nickel fertilizers.
The timing for nickel supplementation should be determined based on the crop's growth cycle and nutrient requirements:
- Seedling stagePromotes vigorous seedling growth
- Vigorous Growth PeriodQuickly Replenish Nutrients
- Flowering and Fruiting StagePromotes flower bud differentiation and fruit development
It is recommended to apply in advance during the critical period when crops need nickel.
Store in original sealed packaging in a cool, dry, and well-ventilated place; shelf life is24 months. Storage precautions:
- Keep away from direct sunlight and humid environments
- Avoid contact with sharp objects to prevent package damage
Use promptly after opening; reseal any unused product.
