Product description
Ethylenediaminetetraacetate nickel sodium is a high-efficiency EDTA chelated nickel fertilizer. The product is a light blue powder with chelated nickel content ≥12.5%, pH (1% aqueous solution) 6.0-7.5, water-insoluble substances ≤0.1%. Uses EDTA chelation technology, with nickel in the form of EDTA chelate, allowing crops to directly absorb it; the absorption rate is significantly higher than conventional inorganic nickel fertilizers.

Application recommendations
Application by Drip Irrigation
Fully water-soluble formula, especially suitable for protected cultivation and precision agriculture; EDTA-chelated nickel can be directly absorbed by crops.
- Concentration: 0.5–2 g/L irrigation water.
- Application rate: 0.5—2 kg/mu/application
- Frequency: every 10–15 days
Foliar Feeding
Rapid nickel replenishment, eliminates deficiency symptoms.
- Dilution ratio: 1:1000 – 1:2000
- Application rate: 30–60 L/mu
- Time: morning or evening, avoid high temperatures
Application with irrigation water
Apply with irrigation water, suitable for nickel replenishment.
- Application rate: 1–3 kg/mu per application.
- Dilution ratio: 1:100 to 1:200
- Timing: key crop growth stages
Mixing water-soluble fertilizers
Used as a nickel source in combination with water-soluble macronutrient fertilizers for balanced nutrition.
- Apply together with water-soluble macronutrient fertilizers
- Dosage: 1–5%
- Suitable for melons, vegetables, fruit trees
Suitable crops and recommended dosages
| Crop Type | Typical crops | Drip irrigation application rate | Application rate for foliar feeding | Application period |
|---|---|---|---|---|
| Fruit Trees | Apple, pear, peach, grape, citrus | 1–2 kg/mu | 1000–2000-fold dilution | Period of germination, flowering and fruit set formation |
| Vegetables | Tomatoes, cucumbers, peppers, eggplants, leafy vegetables | 5 – 1.5 kg/mu | 1000 – 1500 times | Stage of Emergence, Flowering, and Fruiting |
| Field Crops | Wheat, corn, rice, soybean | 0.5 – 1 kg/mu | 1000 – 1500 times | Tillering and stem elongation stage |
| Industrial crops | Tea, Tobacco, Cotton | 1–2 kg/mu | 1000–2000-fold dilution | Active growth period |
- Store in a cool, dry place, avoid direct sunlight; use opened packaging as soon as possible.
- For foliar application, it is recommended to first conduct a small-area test, ensuring no phytotoxicity before widespread use.
- Compatible with most fertilizers and pesticides, but a preliminary small-area test is recommended.
- Before use in drip irrigation, it is recommended to filter the solution to prevent clogging of drippers with impurities.
- When applying nickel, control the dosage to avoid excess.
Frequently asked questions
Typical symptoms of nickel deficiency in plants include:
- Leaf ChlorosisInterveinal Chlorosis of Young Leaves
- Growth RetardationDelayed plant growth
- Leaf tip necrosisAppearance of necrotic spots on leaf tips
- Common Nickel SaltsExists in the form of inorganic salts; plants need to convert it into an absorbable form, resulting in low uptake efficiency.
- Nickel Chelated EDTANickel is in the form of EDTA chelate, "encapsulated" within the EDTA molecule, offering good stability, no soil fixation, and direct uptake by crops with significantly higher absorption efficiency than conventional inorganic nickel fertilizers.
The nickel application period should be determined according to the crop growth cycle and its specific nutrient requirements.
- Emergence PhasePromotes healthy seedling growth
- Active growth periodRapid replenishment of nutrients
- Flowering and Fruiting PeriodStimulates flower bud differentiation and fruit development
It is recommended to apply in advance during the key period of crop nickel demand.
Store in original sealed packaging in a cool, dry place with good ventilation. Shelf Life:24 monthsStorage conditions:
- Keep out of direct sunlight and humid environments.
- Avoid contact with sharp objects to prevent damage to packaging.
Opened packaging should be used as soon as possible; any unused product must be resealed and stored.
