Full oxide chelation technology; calcium and magnesium in amino acid chelated form, directly taken up by plants, with significantly higher absorption efficiency than conventional inorganic secondary nutrient fertilizers. Contains no nitrate nitrogen, ammonium nitrogen, or chloride ions, suitable for eco-friendly agriculture.
Key Advantages
- Comprehensive calcium and magnesium applicationCa+Mg content ≥150 g/L; a single application provides simultaneous replenishment of two key secondary nutrients—calcium and magnesium.

- High Amino Acid ContentAA≥350 g/L, provides rich organic nutrition for crops while enhancing their stress resistance.
- High degree of absorptionAmino acids directly participate in plant metabolism, and the absorption rate of calcium and magnesium can be 3-5 times higher than that of conventional mineral fertilizers.
- Fully water-solubleTransparent liquid, dissolves quickly, no sediment or residue, suitable for foliar application and drip irrigation.
- Prevention of nutrient deficienciesEffectively prevents symptoms of calcium and magnesium deficiencies such as fruit cracking, bitter pit, blossom-end rot, and leaf yellowing.
- Purity and SafetyContains no nitrate nitrogen, ammonium nitrogen, or chloride ions; suitable for eco-friendly agricultural production.

Application recommendations
Foliar Feeding (Recommended)
Fully water-soluble clear liquid, ideal for rapid foliar application of calcium and magnesium, amino acid chelated form directly absorbed through leaves.
- Dilution ratio: 1:500 – 1:1000
- Application rate: 30 — 60 L/mu
- Frequency: once every 7–10 days
- Note: Apply in the morning or evening, avoiding high-temperature periods.
Application by Drip Irrigation
Suitable for protected cultivation and precision agriculture; calcium and magnesium can be directly absorbed and utilized by plant root systems.
- Dilution ratio: 1:200 – 1:500
- Application rate: 2—5 L/mu/application
- Frequency: once every 10–15 days
- Note: Can be used together with water-soluble macronutrient fertilizers.
Application with irrigation water
Applied with irrigation water, suitable for replenishing secondary nutrients in fruit trees, vegetables, and other cash crops.
- Application Rate: 5–10 L/mu/application
- Dilution ratio: 1:100 – 1:200
- Timing: key crop growth stages
- Note: best results are achieved with frequent low-dose applications
Complex application of 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%
- Applied to melons, vegetables, and fruit trees
- Can be used alone or in combination with other amino acid products.
Target crops and recommended application rates
| Crop Type | Typical crops | Drip irrigation rate | Application rate for foliar feeding | Application timing |
|---|---|---|---|---|
| Fruit Trees | Apples, pears, peaches, grapes, citrus | 3–5 L/ha | 500–1000 times | Young fruit stage, fruit filling stage, post-harvest |
| Vegetable Crops | Tomatoes, cucumbers, peppers, eggplants | 2–4 L/ha | 500–1000 times | Seedling stage, flowering stage, fruiting stage |
| Cucurbits | Watermelon, melon, strawberry | 2–4 L/ha | 500–1000 times | Vine growth period, flowering period, fruit filling period |
| Oilseed crops | Rapeseed, Peanut, Soybean | 2–3 L/ha | 500–1000 times | Flowering and pod formation period |
| Root vegetables | Potatoes, carrots, beets | 2–3 L/ha | 500–1000 times | Tuber initiation and bulking period |
- Store in a cool dry place, avoiding direct sunlight. Use opened packaging as soon as possible.
- When applying boron, it is necessary to control the dosage to avoid toxicity due to excess.
- 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 trial and apply over large areas only after confirming no phytotoxicity.
- Before drip irrigation, it is recommended to filter the solution to prevent clogging of emitters with impurities.
Frequently asked questions
Calcium and magnesium have a close synergistic relationship in plants:
- Mutual enhancement of absorptionMagnesium promotes calcium uptake and transport; magnesium deficiency impairs calcium absorption.
- Co-participation in photosynthesisMagnesium is a key component of chlorophyll; calcium participates in stabilizing cell wall structure; together they promote healthy plant growth.
- Prevention of comprehensive nutrient deficiencyDeficiency of both calcium and magnesium affects plant growth and development; simultaneous application can prevent many physiological disorders such as fruit cracking, leaf yellowing, and blossom end rot.
- Improved fruit qualityCombined application of calcium and magnesium significantly increases fruit firmness, shelf life and external quality.
Therefore, simultaneous application of calcium and magnesium is significantly more effective than separate application.
The main difference lies in the chelation process and nutrient form:
- Standard calcium/magnesium fertilizerThey are in the form of inorganic salts (e.g., calcium nitrate, magnesium sulfate, etc.); plants need to convert them into an absorbable form, absorption efficiency is low, and they easily form precipitates and become fixed in soil with phosphate ions, etc.
- Calcium-Magnesium Foliar FertilizerCalcium and magnesium are in the form of amino acid chelates, 'encapsulated' in amino acid molecules, with high stability, not fixed by soil, directly absorbed by plants, with uptake efficiency 3-5 times higher than ordinary inorganic fertilizers.
Furthermore, amino acids themselves are an organic nitrogen source directly assimilated by plants, significantly enhancing crop resilience and product quality.
Calcium and magnesium application timing should be determined based on the crop growth cycle and nutrient requirement characteristics:
- Emergence PhaseStimulates root system development and leaf growth in seedlings
- Flowering stagePromotes pollen development and fertilization, increases fruit set rate.
- Fruit formation periodStimulates cell division and development of young fruits, laying the foundation for fruit enlargement.
- Fruit Filling PeriodPromotes rapid increase in fruit size, prevents cracking and deformation
- After harvestReplenish tree nutrition, restore tree condition
It is recommended to apply in advance during key periods of crop calcium and magnesium demand; prevention is better than cure.
