Area of application
Application recommendations
Foliar Feeding (Recommended)
Fully water-soluble liquid formulation, ideal for foliar feeding; fully chelated oxide nutrients are rapidly absorbed by plants.
- Dilution ratio: 1:500 – 1:1000
- Application rate: 30–60 L/mu
- Timing: morning or evening, avoiding high temperatures
- Note: for best results, spray 2-3 times during fruit development
Drip Irrigation Application
Fully water-soluble formula, suitable for protected cultivation and precision agriculture; calcium, magnesium, and zinc can be directly absorbed by plants.
- Application rate: 5–10 L/mu/application
- Dilution factor: 1:200–1:500
- Frequency: every 10–15 days
- Note: Can be used together with water-soluble macronutrient fertilizers.
Application with irrigation water
Apply with irrigation water, suitable for supplementing micronutrients in fruit trees, vegetables and other industrial crops.
- Application Rate: 10–20 L/mu/time
- Dilution ratio: 1:100 – 1:200
- Timing: key growth stages of crops
- Note: It is better to apply in small doses but more frequently
Mixing water-soluble fertilizers
Used as a source of secondary and micronutrients in combination with water-soluble macronutrient fertilizers to achieve balanced nutrition.
- Use together with water-soluble macronutrient fertilizers
- Application rate: 3 — 8%
- Suitable for melons, vegetables, and fruit trees
- Chloride-free formula, high safety
Suitable crops and recommended dosages
| Crop Type | Typical crops | Rate for drip irrigation | Application rate for foliar feeding | Application timing |
|---|---|---|---|---|
| Fruit Trees | Apple, pear, peach, grape, citrus | 3 – 5 kg/mu | 1000-2000 times | Ovary formation stage, fruit filling, and post-harvest |
| Vegetables | Tomatoes, cucumbers, peppers, eggplants | 2 – 4 kg/mu | 1000 – 1500 times | Seedling stage, flowering stage, fruiting stage |
| Cucurbits | Watermelon, melon, strawberry | 2 – 4 kg/mu | 1000 – 1500 times | Vine growth, flowering, and fruit filling period. |
| Oilseed crops | Rapeseed, Peanut, Soybean | 2 – 3 kg/mu | 1000 – 1500 times | Flowering and pod formation period |
| Root and tuber crops | Potatoes, carrots, beets | 2 – 3 kg/mu | 1000 – 1500 times | Tuber formation 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 small-area trial application is recommended.
- For foliar fertilization, it is recommended to first conduct a small-area test to confirm no phytotoxicity, then apply on a larger scale.
- It is recommended to filter the solution before drip irrigation to prevent clogging of emitters with impurities.
Frequently asked questions
Calcium, magnesium, and zinc in plants are closely interrelated:
- Mutual enhancement of absorptionZinc promotes the uptake and transport of calcium; magnesium participates in photosynthesis and nitrogen metabolism, synergistically improving nutrient use efficiency.
- Participates in plant metabolismCalcium is a major component of the cell wall, magnesium is a key element of chlorophyll, zinc is involved in auxin synthesis and enzyme activation.
- Prevention of complex element deficiencyDeficiency of various elements affects plant growth; combined application helps prevent many physiological disorders such as fruit cracking, bitter pit, small leaves, chlorosis, etc.
- Improved fruit qualityCombined application of calcium, magnesium, and zinc significantly increases fruit firmness, shelf life, and market quality.
Therefore, simultaneous application of multiple elements is much more effective than separate applications.
The main difference lies in the chelation technology and nutrient form.
- Common micronutrient fertilizersElements are present as inorganic salts (e.g., calcium nitrate, zinc sulfate, etc.), requiring conversion by plants into absorbable forms, resulting in low uptake efficiency and prone to precipitation and fixation in soil with phosphate ions, etc.
- Foliar calcium-magnesium-zinc fertilizerElements are present in the form of full chelates of oxides; calcium, magnesium, and zinc are 'encapsulated' in amino acid molecules, ensuring good stability, resistance to soil fixation, and direct plant uptake. The absorption rate can be 3-5 times higher than conventional inorganic fertilizers. At the same time, there is no nitrate or ammonium nitrogen, or chloride ions, which increases safety.
Furthermore, amino acids themselves are an organic nitrogen source directly assimilated by plants, significantly enhancing their stress tolerance and product quality.
The application period of micronutrients should be determined according to the crop growth cycle and its nutritional characteristics:
- Emergence PhaseStimulates seedling growth, enhances photosynthesis
- Flowering periodStimulates pollen germination and fertilization, improves fruit set
- Fruit set periodStimulates cell division and development in young fruits, laying the foundation for fruit enlargement
- Fruit Filling PeriodPromotes rapid increase in fruit size, prevents cracking and deformation
- After harvestReplenishes tree nutrition and restores their condition.
It is recommended to apply in advance during key periods of crop micronutrient demand; prevention is better than cure.
