Product description
Product overview
Amino Acid Chelated Calcium, Magnesium, Zinc, and Boron (Chelate Strong) is a highly effective chelated micronutrient fertilizer. The product is a yellow fully soluble powder with amino acids ≥30%, calcium ≥10%, magnesium ≥2%, boron ≥0.5%, zinc ≥0.5%, pH 6-8. Through amino acid chelation technology, calcium, magnesium, zinc, and boron are in chelated form, ensuring direct plant uptake and significantly higher efficiency compared to conventional inorganic micronutrient fertilizers.
Key Advantages

Area of application
Application recommendations
Application via drip irrigation (recommended)
Fully water-soluble formula, ideal for protected cultivation and precision agriculture. The chelated micronutrients with amino acids are directly absorbed by plants.
- Concentration: 0.5 – 1 g/L irrigation water
- Application rate: 2–5 kg/mu/application
- Frequency: every 10–15 days
- Note: Can be used together with water-soluble macronutrient fertilizers.
Foliar Feeding
Rapidly replenishes calcium, magnesium, zinc, and boron, correcting deficiency symptoms, especially suitable during fruit development and flowering.
- Dilution ratio: 1:1000 – 1:2000
- Application rate: 30 — 60 L/mu
- Timing: morning or evening, avoiding high temperatures
- Note: for best results, it is recommended to carry out 2-3 consecutive sprays during flowering and fruit development.
Fertigation
Applied with irrigation water, suitable for supplementing secondary and micronutrients in fruit trees, vegetables, and other industrial crops.
- Application rate: 5 – 10 kg/mu/time
- Dilution ratio: 1:100 – 1:200
- Timing: key plant growth stages
- Note: It is better to apply in small doses but more frequently
Mixing water-soluble fertilizers
Used as a source of meso- and micronutrients in combination with water-soluble macronutrient fertilizers to achieve balanced nutrition.
- Use together with water-soluble macronutrient fertilizers
- Dosage: 3–8%
- Used for melons, vegetables, and fruit trees
- Can be used alone or in combination with other amino acid products.
Suitable crops and recommended dosages
| Crop Type | Main crops | Drip irrigation application rate | Foliar application rate | Application period |
|---|---|---|---|---|
| Fruit Trees | Apple, pear, peach, grape, citrus | 3 – 5 kg/mu | 1000-2000 times | Fruit set, fruit filling, and post-harvest periods |
| Vegetables | Tomatoes, cucumbers, peppers, eggplants | 2 – 4 kg/mu | 1000 – 1500 times | Seedling, flowering, and fruiting stages |
| Fruit and berry crops | Watermelon, melon, strawberry | 2 – 4 kg/mu | 1000 – 1500 times | Vine growth period, flowering period, fruit filling period |
| Oilseed crops | Rapeseed, Peanut, Soybean | 2 – 3 kg/mu | 1000 – 1500 times | Flowering and pod formation period |
| Root vegetables | Potatoes, carrots, beets | 2 – 3 kg/mu | 1000 – 1500 times | Tuber initiation and bulking period |
- Store in a cool, dry place, avoid direct sunlight; use opened packaging as soon as possible.
- Boron dosage must be controlled to avoid excess and toxicity.
- Compatible with most fertilizers and pesticides, but a small-scale preliminary test is recommended.
- For foliar fertilization, it is recommended to first conduct a small-area test to confirm no phytotoxicity, then apply on a larger scale.
- Before use in drip irrigation, it is recommended to filter the solution to prevent clogging of drippers with impurities.
Frequently asked questions
Calcium, magnesium, zinc, and boron interact closely in plants:
- Mutual enhancement of absorptionBoron promotes calcium absorption and transport, zinc is involved in auxin synthesis; element deficiency affects overall growth.
- Joint participation in plant metabolismCalcium is the main component of cell walls, magnesium is a key component of chlorophyll, and zinc and boron are involved in activating many enzymes.
- Prevention of complex element deficiencyDeficiencies of various elements affect crop growth; simultaneous application can prevent physiological disorders such as fruit cracking, bitter pit, small leaves, chlorosis, and others.
- Improved fruit qualityCombined application of calcium, magnesium, zinc, and boron significantly improves fruit firmness, storability, and appearance quality.
Therefore, simultaneous application of multiple elements is much more effective than separate application.
The main difference lies in the chelation process and nutrient form:
- Common Meso- and Micronutrient FertilizersBeing in the form of inorganic salts (e.g., calcium nitrate, borax, zinc sulfate, etc.), they require conversion into absorbable forms by plants, have low uptake efficiency, and are prone to precipitation and fixation in soil, for example, with phosphate ions.
- Amino acid chelated calcium, magnesium, zinc, and boronIn the form of amino acid chelates, calcium, magnesium, zinc, and boron are "encapsulated" within amino acid molecules, ensuring good stability, resistance to soil fixation, and direct plant uptake. Absorption efficiency can be 3-5 times higher than that of conventional inorganic fertilizers.
Furthermore, amino acids themselves are an organic nitrogen source directly assimilated by plants, significantly enhancing their stress tolerance and product quality.
The application period for secondary and micronutrients should be determined based on the crop growth cycle and nutrient requirement characteristics:
- Emergence PhaseStimulates seedling growth and enhances photosynthesis
- Flowering periodPromotes pollen germination and fertilization, increases fruit set rate.
- Fruit formation periodStimulates cell division and development in young fruits, laying the foundation for fruit enlargement
- Fruit Filling PeriodPromotes rapid fruit size increase, prevents cracking and deformation.
- After harvestReplenish tree nutrition, restore tree condition
It is recommended to apply in advance during key periods of crop demand for secondary and micronutrients; prevention is better than cure.
