Product Overview
Product Overview
Amino Acid Chelated Ca-B is a highly effective medium-element fertilizer with chelated amino acids. It is a yellow, fully soluble powder with amino acids ≥35%, calcium ≥10%, boron ≥2%, and pH 6-8. Using amino acid chelation technology, calcium and boron exist in chelated form, allowing direct crop uptake with absorption rates far exceeding ordinary inorganic medium-element fertilizers.
Core Advantages
- Calcium & Boron CombinedCa≥10%, B≥2%; supplies two key secondary nutrients in a single application
- Amino Acid Chelation TechnologyCalcium and boron exist in amino acid chelated form, offering high stability and resistance to soil fixation
- High Amino Acid ContentAA≥35%, provides rich organic nutrients to crops while enhancing stress resistance
- High absorption and utilization rateAmino acids can directly participate in crop metabolism, with calcium and boron absorption rates 3-5 times higher than ordinary inorganic fertilizers.
- Fully Water SolubleYellow fully soluble powder, dissolves quickly, no sediment or residue, suitable for various irrigation systems.
- Prevent nutrient deficiencyEffectively prevents fruit cracking, bitter pit, blossom end rot, fruit shrinkage, flower but no fruit, and other calcium and boron deficiency symptoms.

Application scenarios
Application Reference
Drip irrigation application (recommended)
Fully water-soluble formula, especially suitable for facility agriculture and precision fertilization. Amino acid chelated medium elements can be directly absorbed by crops.
- Concentration: 0.5 — 1 g/L irrigation water
- Application rate: 2 – 5 kg/mu/time
- Frequency: Every 10 — 15 days
- Note: Can be used in combination with water-soluble NPK fertilizers
Foliar Application
Rapidly replenishes calcium and boron, corrects deficiency symptoms, especially suitable for fruit development and flowering stages.
- Dilution ratio: 1:1000 — 1:2000
- Application rate: 30 — 60 L/mu
- Time: Morning or evening, avoid high temperatures
- Note: Apply 2-3 consecutive sprays during flowering and fruit development for best results
Fertigation
Apply through irrigation for top-dressing; suitable for supplementing secondary nutrients in fruit trees, vegetables, and other cash crops.
- Dosage: 5 – 10 kg/mu/time
- Dilution ratio: 1:100 — 1:200
- Time: Critical Growth Period of Crops
- Note: Better results with small amounts applied frequently
Water-Soluble Fertilizer Blending
Use as a secondary nutrient source together with water-soluble NPK fertilizers for balanced nutrition.
- Use with water-soluble NPK fertilizers
- Addition Ratio: 3–8%
- Suitable for melons, vegetables, and fruit trees
- Can be used alone or with other amino acid products
Suitable Crops & Recommended Dosage
| Crop Type | Representative crops | Drip Irrigation Dosage | Foliar Spray Dosage | Application Period |
|---|---|---|---|---|
| Fruit Trees | Apples, Pears, Peaches, Grapes, Citrus | 3 — 5 kg/mu | 1000–2000x Dilution | Young Fruit Stage, Fruit Expansion Stage, Post-Harvest |
| Vegetables | Tomato, cucumber, pepper, eggplant | 2 — 4 kg/mu | 1000–1500x Dilution | Seedling Stage, Flowering Stage, Fruiting Stage |
| Melons & Fruits | Watermelon, melon, strawberry | 2 — 4 kg/mu | 1000–1500x Dilution | Vine extension, flowering, and fruit expansion stages |
| Oilseed Crops | Rapeseed, Peanuts, Soybeans | 2 — 3 kg/mu | 1000–1500x Dilution | Flowering and Podding Stages |
| Root and tuber crops | Potatoes, Carrots, Beets | 2 — 3 kg/mu | 1000–1500x Dilution | Tuber Formation & Bulking Stages |
- Store in a cool, dry place away from direct sunlight; use promptly after opening.
- Control the dosage of boron to avoid boron toxicity from overuse.
- Can be mixed with most fertilizers and pesticides, but a small-scale test is recommended before use.
- When applying foliar spray, it is recommended to conduct a small-area test first to confirm no phytotoxicity before large-scale use.
- Before drip irrigation, filter the solution to prevent impurities from clogging the drippers.
FAQ
Calcium and boron have a close synergistic relationship within the plant:
- Mutual absorption enhancementBoron promotes calcium absorption and transport; boron deficiency affects calcium uptake and utilization.
- Jointly Involved in Cell Wall FormationCalcium is a major component of cell walls, and boron participates in cell wall structural stability; together they synergistically promote cell wall health.
- Prevent comprehensive nutrient deficiencyCalcium and boron deficiencies both affect fruit development; simultaneous supplementation can prevent various physiological disorders such as fruit cracking, fruit shrinkage, and bitter pit.
- Improves fruit qualityCo-application of calcium and boron significantly improves fruit firmness, storage life, and appearance quality.
Therefore, supplementing calcium and boron together is far more efficient than supplementing them separately.
The main differences lie in the chelation process and nutrient form
- Common Calcium/Boron FertilizerExisting in inorganic salt form (e.g., calcium nitrate, borax), crops need to convert them into absorbable forms, resulting in lower absorption rates and easy precipitation fixation with soil phosphates.
- Amino Acid Chelated Calcium BoronExisting in amino acid chelated form, calcium and boron are "wrapped" by amino acid molecules, ensuring high stability and resistance to soil fixation. Crops can directly absorb and utilize them, with absorption rates 3-5 times higher than ordinary inorganic fertilizers.
Additionally, amino acids themselves are organic nitrogen sources that crops can directly utilize, significantly improving crop stress resistance and quality.
The timing for calcium and boron supplementation should be determined based on crop growth stages and nutrient requirements.
- Flowering PeriodPromotes pollen germination and fertilization, increases fruit set rate
- Young Fruit StagePromotes young fruit cell division and development, laying the foundation for fruit enlargement
- Fruit expansion stagePromotes rapid fruit enlargement, prevents cracking and malformation
- After HarvestSupplement tree nutrition, restore tree vigor, and prepare for next year's flower bud differentiation.
It is recommended to apply before the critical period of calcium and boron demand, as prevention is better than cure.
