Product description
Product overview
Amino Acid Chelated Ca-B is a highly effective mesonutrient fertilizer in amino acid chelate form. The product is a fully soluble yellow powder with amino acids ≥35%, calcium ≥10%, boron ≥2%, pH 6-8. Through amino acid chelation technology, calcium and boron are in chelated form, ensuring direct plant uptake with much higher efficiency compared to conventional inorganic mesonutrient fertilizers.
Key Advantages
- Combined application of calcium and boronCa≥10%, B≥2%, single application provides two key secondary elements.
- Amino Acid Chelation TechnologyCalcium and boron are in amino acid chelated form, offering good stability and not fixed by soil.
- High Amino Acid ContentAA≥35%, provides rich organic nutrition for crops while enhancing their stress resistance.
- High degree of absorptionAmino acids can directly participate in plant metabolism, and the absorption rate of calcium and boron can be 3-5 times higher than that of conventional inorganic fertilizers.
- Fully water-solubleYellow fully soluble powder, dissolves quickly, no sediment or residue. Suitable for various irrigation systems.
- Prevention of nutrient deficienciesEffectively prevents calcium and boron deficiency symptoms such as fruit cracking, bitter pit, blossom end rot, fruit deformation, hollow fruit, etc.

Application recommendations
Drip Irrigation (Recommended)
Fully water-soluble formula especially suitable for protected cultivation and precision agriculture; mesonutrients in amino acid chelate form 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 (spraying)
Rapidly corrects calcium and boron deficiencies, alleviating deficiency symptoms. Especially suitable for application during fruit development and flowering.
- Dilution ratio: 1:1000 – 1:2000
- Application rate: 30 — 60 L/mu
- Time: morning or evening, avoiding high temperature
- Note: For best results, apply 2-3 sprays during flowering and fruit development stages.
Application with irrigation water
Applied with irrigation water, suitable for supplementing secondary nutrients in fruit trees, vegetables, and other cash crops.
- Dosage: 5–10 kg/mu/application
- Dilution ratio: 1:100–1:200
- Application timing: key crop growth stages
- Note: It is better to apply in small doses but more frequently
Mixing water-soluble fertilizers
Used as a source of secondary elements in combination with water-soluble macronutrient fertilizers for balanced nutrition.
- Apply together with water-soluble macronutrient fertilizers
- Dosage: 3–8%
- Suitable 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 | Representative Crops | Drip irrigation rate | Application rate for foliar feeding | Application Timing |
|---|---|---|---|---|
| Fruit Trees | Apple, pear, peach, grape, citrus | 3 – 5 kg/mu | 1000-2000 times | During fruit set, fruit growth, and post-harvest periods |
| Vegetable Crops | Tomato, cucumber, pepper, eggplant | 2 – 4 kg/mu | 1000 – 1500 times | Germination, Flowering, Fruit Set Stages |
| Fruit and berry crops | Watermelon, melon, strawberry | 2 – 4 kg/mu | 1000 – 1500 times | Vine growth, flowering, and fruit filling stages |
| 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 preliminary small-area test is recommended.
- For foliar application, it is recommended to first conduct a small-area test to ensure no phytotoxicity, then apply on larger areas.
- It is recommended to filter the solution before drip irrigation to prevent clogging of drippers with impurities.
Frequently asked questions
Calcium and boron have a close synergistic interaction in plants:
- Mutual enhancement of absorptionBoron promotes the uptake and transport of calcium; boron deficiency affects calcium absorption and utilization.
- Participates in cell wall formationCalcium is a major component of the cell wall, boron participates in stabilizing its structure; their combined action promotes cell wall health.
- Prevention of comprehensive nutrient deficiencyDeficiency of both calcium and boron affects fruit development; their combined application helps prevent many physiological disorders such as fruit cracking, deformation, and bitter pit.
- Improved fruit qualityCombined application of calcium and boron significantly improves fruit firmness, shelf life, and external quality.
Thus, simultaneous application of calcium and boron is significantly more effective than separate application.
The main difference lies in the chelation technology and nutrient form.
- Ordinary calcium/boron fertilizerThey are in the form of inorganic salts (e.g., calcium nitrate, borax, etc.), require conversion into assimilable forms by plants, have low bioavailability, and easily form precipitates and immobilize in the soil, e.g., with phosphate ions.
- Amino Acid Chelated Calcium and BoronCalcium and boron are in the form of amino acid chelate, 'encapsulated' in the amino acid molecule, ensuring high stability, resistance to soil fixation, and direct absorption by plants with efficiency 3-5 times higher than ordinary inorganic fertilizers.
Additionally, amino acids themselves are an organic nitrogen source directly assimilated by plants, significantly enhancing stress resistance and product quality.
The application period for calcium and boron should be determined according to the crop growth cycle and its specific nutrient needs:
- Flowering periodPromotes pollen germination and fertilization, increases fruit set rate.
- Fruit formation periodStimulates cell division and development in young fruits, laying the foundation for enlargement.
- Fruit Filling PeriodPromotes rapid fruit enlargement, prevents cracking and deformation.
- After harvestReplenish tree nutrition, restore growth vigor, prepare for flower bud differentiation the following year.
Recommended to apply in advance during key periods of crop calcium and boron demand; prevention is better than cure.
