Zinc Fulvate is a highly advanced organic micronutrient fertilizer, created through a precise process that chelates zinc with fulvic acid. This unique formulation solves key agricultural challenges by enhancing zinc availability and boosting soil health.
Key Advantages:
(1)Ultra-High Absorption: Chelation prevents zinc from binding with soil particles, increasing plant uptake to over 80%—significantly higher than zinc sulfate.
(2)Soil Disease Suppression: Reduces harmful pathogens and minimizes soil-borne diseases, supporting continuous cropping.
(3)Improved Crop Quality: Enh physiological traits and fruit quality, making it essential for high-value crops.
Functional Fertilizer Component: Ideal for blending into advanced fertilizer mixes for optimized nutrition.

| Chelated Zinc | ≥4.5% |
| Usage Methods | Foliar spraying, Root irrigation/drip irrigation, Seed dressing/seed soaking |
1. Foliar Spray: For rapid absorption and quick correction of zinc deficiency. Apply evenly on leaves, avoiding direct spray on fruits during the fruit-setting period to prevent possible residue.
2. Drip Irrigation / Soil Drench: Supplies zinc directly to the root zone, ideal for long-term soil conditioning and sustained zinc availability.
3. Seed Treatment: Soak or coat seeds before sowing to improve germination, boost early seedling vigor, and enhance stress resistance.
1. Cereals: maize (prevents "white seedling"), rice (reduces seedling mortality), wheat (improves tillering and grain filling).
2. Fruit Trees: apples (counteracts "little leaf disease"), citrus (minimizes leaf yellowing and fruit sizing issues), grapes (supports bloom and fruit development).
3. Vegetables: tomatoes (reduces leaf curl and fruit deformity), cucumbers (prevents stunted growth), peppers (enhances yield quality).
4. Commercial Crops: cotton (reduces chlorosis and improves boll formation), rapeseed (promotes growth and flowering).
Field tests demonstrate that zinc humate significantly boosts crop performance. In summer maize, application at 200 mg/L increased grains per ear (543.0), thousand-kernel weight (296.3 g), and yield (8636.9 kg/hm²), achieving an 8.31% yield increase. Combined with urea and potassium humate, it further enhances kernel count and weight.
Q: What is Zinc Fulvate?
A: Zinc Fulvate is a water-soluble form of zinc that is easily absorbed by plants.
