Product introduction
Product Overview
Poly Amino Acid Zinc is a high-concentration organic zinc fertilizer produced using poly-amino acid chelation technology. It is a blue liquid with free amino acid content ≥350g/L, zinc content ≥110g/L, and pH 5-7. Zinc exists in a chelated poly-amino acid form, allowing direct crop absorption and effectively preventing and correcting zinc deficiency symptoms.
Core Advantages
- High Concentration Organic ZincZinc content ≥110g/L, polyaspartic acid chelated form, high stability.
- Efficient AbsorptionAmino acid chelation technology enhances zinc absorption by 3-5 times compared to conventional inorganic zinc fertilizers.
- Dual NutritionFree amino acids ≥350g/L, simultaneously supplies zinc and organic nitrogen.
- Fully Water-SolubleDissolves rapidly, suitable for drip irrigation, foliar spray, and various application methods.
- Prevent Zinc DeficiencyEffectively prevents zinc deficiency symptoms such as little leaf, albino seedlings, and rosette leaves.
- Safe and StablepH value 5-7, friendly to crops and soil
Applicable Scenarios
Application Guide
Drip irrigation application (recommended)
Fully water-soluble formula, ideal for protected agriculture and precision fertilization; polyaspartic acid chelated zinc can be directly absorbed by crops.
- Concentration: 500 — 1000 times dilution
- Application rate: 1 — 3 L/mu/time
- Frequency: every 10–15 days
- Note: Can be used with water-soluble macroelement fertilizers
Foliar spray
Rapidly replenishes zinc, correcting zinc deficiency symptoms, especially suitable for use during the seedling and growth stages.
- Dilution ratio: 800 — 1200 times
- Application rate: 30 — 60 L/mu
- Time: morning or evening, avoid high temperatures
- Note: Using with insecticides improves effectiveness
Drench
Apply via drip irrigation or fertigation along with watering, suitable for supplementing zinc in fruit trees, vegetables, and other cash crops.
- Dosage: 2 — 5 L/mu/time
- Dilution ratio: 1:200 — 1:500
- Timing: Key crop growth stages
- Note: Better results with small, frequent applications
Water-Soluble Fertilizer Blending
Used as a zinc source in combination with water-soluble macro-element fertilizers to achieve balanced nutrition.
- Used with high-content water-soluble fertilizer
- Addition ratio: 1–3%
- Suitable for melons, vegetables, and fruit trees
- Can be used alone or with other micronutrient products
Applicable Crops & Recommended Dosage
| Crop Type | Representative Crops | Drip Irrigation Dosage | Foliar spray dilution ratio | Application Period |
|---|---|---|---|---|
| Fruit trees | Apple, Pear, Peach, Grape, Citrus | 2 — 3 L/mu | 800–1000 times dilution | Budding stage, shoot growth stage |
| Vegetables | Tomato, cucumber, pepper, eggplant | 1 — 2 L/�� | 800–1200 times dilution | Seedling Stage, Flowering Stage |
| Field Crops | Corn, wheat, rice | 1 — 2 L/mu | 800–1000 times dilution | Seedling Stage, Jointing Stage |
| Oil crops | Soybeans, peanuts, rapeseed | 1 — 2 L/mu | 800–1000 times dilution | Seedling Stage, Flowering Stage |
| Cash Crops | tobacco, tea, cotton | 1 — 2 L/mu | 800–1200 times dilution | Growing season, pre-harvest |
- Store in a cool, dry place, away from direct sunlight and freezing.
- Zinc dosage should be carefully controlled to avoid toxicity from over-application.
- Can be mixed with most fertilizers and pesticides, but a small-scale test is recommended before use.
- For foliar application, it is recommended to conduct a small-scale test first to confirm no phytotoxicity before large-scale use.
- Filter the solution before drip irrigation to prevent impurities from clogging the drippers.
FAQ
Typical symptoms of zinc deficiency in crops include:
- Leaf SymptomsInterveinal chlorosis and yellowing on new leaves, forming yellow-white spots; leaves become smaller and narrower, showing "little leaf disease."
- Plant SymptomsStunted growth, shortened internodes, dwarfing, forming "rosette"
- Fruit SymptomsSmall, misshapen fruit with reduced quality
Corn zinc deficiency shows as "white seedlings," rice as "stunted seedlings," and fruit trees as "little leaf disease" and "rosette leaves."
The main differences lie in chelation technology and nutrient form
- Common zinc fertilizerExists in inorganic salt form (e.g., zinc sulfate), requiring crop conversion to an absorbable form with low absorption efficiency.
- Polyamino Acid Chelated ZincZinc exists in a chelated poly-amino acid form with excellent stability, allowing direct crop absorption and achieving an absorption rate 3-5 times that of ordinary inorganic zinc fertilizers.
Amino acids themselves are organic nitrogen sources directly usable by crops, significantly enhancing stress resistance and quality.
Zinc application timing should be determined based on crop growth cycles and nutrient requirements:
- Seedling stagepromotes seedling growth and development
- New Shoot Growth PeriodMeets zinc requirements for new leaf growth
- Before and After FloweringPromotes flower bud differentiation, flowering, and fruit set
- Fruit Expansion PeriodPromotes normal fruit development and improves quality
It is recommended to apply zinc before key growth stages, as prevention is better than correction.
