Product description
Product overview
Amino Acid Chelated Calcium-Zinc-Boron (Amino Acid Chelated Ca-Zn-B) is a high-efficiency micronutrient fertilizer in amino acid chelated form. The product is a fully soluble yellow powder: total amino acids ≥30%, free amino acids ≥20%, polypeptides+small peptides ≥10%, calcium ≥15%, boron ≥1%, zinc ≥2%, pH 6-8, chloride-free. Using amino acid chelation technology, calcium, zinc, and boron are in chelated form, enabling direct plant uptake with much higher efficiency compared to conventional inorganic micronutrient fertilizers.

Applications
Application recommendations
Drip Irrigation (Recommended)
Fully water-soluble formula, especially suited for protected cultivation and precision agriculture. Amino acid chelates of mesonutrients are directly taken up 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
Quickly replenishes calcium, zinc, and boron, eliminating deficiency symptoms, especially suitable for use 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, spray 2–3 times during the flowering and fruit development period
Application with irrigation water
Applied with irrigation water (fertigation), suitable for replenishing secondary nutrients in fruit trees, vegetables, and other row crops.
- Application rate: 5–10 kg/mu/time
- Dilution ratio: 1:100 – 1:200
- Timing: key crop growth period
- Note: It is better to apply in small doses but more frequently
Composition of water-soluble fertilizers
Used as a source of secondary elements in combination with water-soluble macronutrient fertilizers for balanced nutrition.
- Applied together with water-soluble macro-nutrient 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 dosage
| Crop Type | Typical crops | Application rate for drip irrigation | Foliar application rate | Application period |
|---|---|---|---|---|
| Fruit tree | Apple, pear, peach, grape, citrus | 3 – 5 kg/mu | 1000-2000 times | Period of fruit set, fruit filling, and post-harvest |
| Vegetables | Tomatoes, cucumbers, peppers, eggplants | 2 – 4 kg/mu | 1000 – 1500 times | Seedling stage, flowering stage, fruiting stage |
| 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 Podding Period |
| Root and tuber crops | 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 as soon as possible after opening the package.
- 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 test on a small area and use on larger areas only after confirming no phytotoxicity.
- It is recommended to filter the solution before drip irrigation to avoid clogging drippers with impurities.
Frequently asked questions
Calcium, zinc, and boron interact closely in plants:
- Mutual enhancement of absorptionBoron promotes calcium uptake and transport; zinc is involved in auxin synthesis. The synergistic action of the three elements improves nutrient use efficiency.
- Joint participation in plant metabolismCalcium is a major component of cell walls, zinc participates in the activation of many enzymes, boron promotes flowering and fruit set.
- Prevention of complex element deficiencyDeficiency of various elements affects plant growth. Their simultaneous replenishment helps prevent multiple physiological disorders such as fruit cracking, bitter pit, small leaves, chlorosis, and blossom without fruit set.
- Improved fruit qualityCombined application of calcium, zinc, and boron significantly improves fruit firmness, storability, and external quality.
Therefore, simultaneous application of multiple elements is much more effective than separate application.
The main difference between them lies in the chelation process and the form of nutrients:
- Common Meso- and Micronutrient FertilizersThey exist as inorganic salts (e.g., calcium nitrate, borax, zinc sulfate). Plants need to convert them into absorbable forms, uptake efficiency is low, and they are prone to precipitation and fixation in soil, e.g., with phosphate ions.
- Calcium, zinc and boron chelate based on amino acidsPresent as amino acid chelates: calcium, zinc and boron are 'encapsulated' in amino acid molecules, ensuring good stability, resistance to soil fixation, and direct plant uptake. Absorption efficiency can be 3-5 times higher than conventional inorganic fertilizers.
Furthermore, amino acids themselves are an organic nitrogen source directly assimilated by plants, significantly enhancing crop resilience and product quality.
The application timing for calcium, zinc, and boron should be determined according to the crop growth cycle and nutrient uptake characteristics:
- Emergence PhaseStimulates seedling growth, enhances photosynthesis
- Flowering periodStimulates pollen germination and fertilization, improves fruit set
- Young fruit stageStimulates cell division and development in young fruits, laying the foundation for fruit enlargement
- Fruit Filling PeriodPromotes rapid fruit enlargement, prevents cracking and deformation.
- After harvestReplenishes tree nutrition, restores growth vigor
It is recommended to apply in advance during key periods of crop calcium, zinc, and boron demand; prevention is better than cure.
