Product Introduction
Product Overview
Amino Acid Chelated Ca-Mg is a highly effective amino acid chelated secondary element fertilizer. It is a yellow, fully soluble powder with amino acid content ≥35%, calcium ≥10%, magnesium ≥2%, and pH 8-9. Using amino acid chelation technology, calcium and magnesium exist in chelated form for direct crop absorption, with absorption rates far exceeding ordinary inorganic secondary element fertilizers.
Core Advantages
- Calcium & Magnesium SupplementCalcium ≥10%, magnesium ≥2%, supplies two key secondary nutrients in a single application.
- Amino Acid Chelation TechnologyCalcium and magnesium exist in amino acid chelated form, with good stability and not easily fixed by soil.
- High Amino Acid ContentAA ≥35%, provides rich organic nutrients while enhancing crop stress resistance.
- High Absorption and Utilization RateAmino acids directly participate in crop metabolism, and calcium-magnesium absorption rates can reach 3–5 times that of conventional inorganic fertilizers.
- Fully Water-SolubleYellow fully soluble powder, dissolves quickly with no sediment or residue, suitable for all irrigation systems.
- Prevention of Deficiency SymptomsEffectively prevents symptoms of calcium deficiency such as fruit cracking, bitter pit, and blossom-end rot, as well as magnesium deficiency symptoms like leaf yellowing.

| Calcium & Magnesium Supplement | Calcium 10% + Magnesium 2%, a dual supplement of two medium elements | Supplement during fruit development, flowering and fruiting stages |
| High Amino Acid Content | Amino acids ≥35%, providing rich organic nutrition | Enhance crop stress resistance and improve quality |
| Fully Water-Soluble | Dissolves quickly, no sediment or residue | Use for drip irrigation, foliar spray, and flood irrigation |
Application Scenarios
Application Reference
Drip Irrigation Application (Recommended)
Fully water-soluble formula, ideal for protected agriculture and precision fertilization; chelated amino acid medium elements are 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 together with water-soluble macroelement fertilizers
Foliar Spray
Quickly supplements calcium and magnesium, correcting 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: For best results, spray 2-3 times during fruit development
Foliar Irrigation
Apply via irrigation for fruit trees, vegetables, and other cash crops to supplement secondary nutrients.
- Dosage: 5 — 10 kg/mu/time
- Dilution ratio: 1:100 — 1:200
- Timing: Key Crop Growth Stages
- Note: Small, frequent applications yield better results
Water-Soluble Fertilizer Compounding
Use as a secondary nutrient source with water-soluble macroelement fertilizers for balanced nutrition.
- Use with High-Element Water-Soluble Fertilizer
- Addition ratio: 3 – 8%
- Suitable for melons, vegetables, and fruit trees
- Can be used alone or in combination with other amino acid products
Applicable Crops and Recommended Dosage
| Crop Type | Representative Crops | Drip Irrigation Dosage | Foliar Spray Dosage | Application Period |
|---|---|---|---|---|
| Fruit Trees | Apple, pear, peach, grape, citrus | 3 – 5 kg/mu | 1000 — 2000 times dilution | Young fruit stage, expansion stage, post-harvest |
| Vegetables | Tomato, Cucumber, Pepper, Eggplant | 2 — 4 kg/ha | 1000 — 1500 times dilution | Seedling, Flowering, Fruiting Stages |
| Melons and fruits | Watermelon, Melon, Strawberry | 2 — 4 kg/ha | 1000 — 1500 times dilution | Vine elongation stage, flowering stage, expansion stage |
| Oilseed Crops | Rapeseed, peanut, soybean | 2 – 3 kg/mu | 1000 — 1500 times dilution | Flowering and Podding Stages |
| Root & Tuber Vegetables | Potatoes, Carrots, Beets | 2 – 3 kg/mu | 1000 — 1500 times dilution | Tuber formation and bulking stages |
- Store in a cool, dry place away from direct sunlight; use promptly after opening.
- Before mixing with other fertilizers, it is recommended to conduct a small-scale test.
- Can be mixed with most fertilizers and pesticides, but a small-area test is recommended before use.
- For foliar application, conduct a small-area test first to confirm no phytotoxicity before large-scale use.
- Before drip irrigation use, filter the solution to prevent impurities from clogging drippers.
FAQ
Calcium and magnesium have a close synergistic relationship within crops:
- Mutual Absorption EnhancementMagnesium promotes calcium absorption and transport; magnesium deficiency can affect calcium uptake and utilization.
- Participate together in crop metabolismCalcium is a key component of cell walls, while magnesium is the core element of chlorophyll; both work synergistically to promote healthy crop growth.
- Prevent Comprehensive Nutrient DeficiencyBoth calcium and magnesium deficiencies affect crop growth; simultaneous supplementation can prevent various physiological disorders such as fruit cracking, bitter pit, and yellowing.
- Improved Fruit QualityCombined calcium and magnesium supplementation can significantly improve fruit firmness, storage life, and appearance quality.
Therefore, supplementing calcium and magnesium together is far more efficient than supplementing them separately.
The main difference lies in the chelation process and nutrient form:
- Common Calcium/Magnesium FertilizersIn inorganic salt form (e.g., calcium nitrate, magnesium sulfate), crops need to convert them into absorbable forms, resulting in lower absorption rates and easy precipitation with phosphates in the soil.
- Amino Acid Chelated Calcium MagnesiumChelated with amino acids, calcium and magnesium are "wrapped" by amino acid molecules, providing good stability, resisting soil fixation, and allowing direct crop absorption with absorption rates 3-5 times higher than ordinary inorganic fertilizers.
Amino acids themselves serve as a directly usable organic nitrogen source for crops, significantly enhancing stress resistance and quality.
The timing of calcium and magnesium supplementation should be determined based on crop growth cycles and nutrient requirements.
- Seedling stagePromotes seedling growth, enhances photosynthesis
- Flowering PeriodPromotes pollen germination and fertilization, improves fruit set rate
- Young Fruit StagePromotes cell division and development in young fruit, laying the foundation for fruit enlargement
- Fruit Expansion StagePromotes rapid fruit enlargement, prevents cracking and malformation
- After harvestReplenish tree nutrients, restore tree vigor
It is recommended to apply before key calcium and magnesium demand periods in crops; prevention is better than cure.
