Common Zinc Problems We Solve

😟 Stunted, rosette growth with short internodes
✅ 14% chelated zinc promotes normal internode development
😟 Small, narrow "little leaf" symptoms in trees
✅ Restores proper leaf expansion and size
😟 Bronze spots and interveinal chlorosis on new growth
✅ Corrects deficiency visible within 2-4 weeks
😟 Poor fruit set and delayed maturity
✅ Supports pollen function and seed development

🌱 Prevents Stunted Growth

14% chelated zinc corrects deficiencies that cause shortened internodes and small, distorted leaves.

⚡ Activates 300+ Enzymes

Essential cofactor for enzyme systems involved in protein synthesis and growth regulation.

💧 Superior Bioavailability

EDTA chelation ensures zinc remains available in soils up to pH 7.0, preventing tie-up.

🛡️ Enhances Stress Tolerance

Improves drought, cold, and disease resistance by supporting plant defense mechanisms.

🌸 Improves Fruit Set

Critical for pollen viability and successful pollination leading to better yields.

🔬 5-10× More Efficient

Chelated form delivers more zinc per pound than zinc sulfate, especially in high pH soils.

🔍 Zinc Deficiency Signs

🍂
Interveinal Chlorosis
Yellowing between veins on young leaves
📏
Little Leaf
Abnormally small, narrow leaves
🌀
Rosette Growth
Short internodes create clustered appearance
🟤
Bronze Spots
Necrotic spots, especially on beans
🌾
White Bud (Corn)
Young corn leaves emerge white/pale
Delayed Maturity
Slow growth and poor fruit/seed set

⚠️ Important Application Guidelines

  • Soil test first: Critical level is 0.5-1.0 ppm DTPA-extractable Zn
  • Don't overapply: Zinc can be toxic at high levels - follow rates carefully
  • Avoid high pH soils: Above pH 7.0, use foliar application or higher rates
  • Monitor tissue levels: Optimal range is 20-60 ppm for most crops
  • Hydroponics caution: Toxic above 0.5 ppm - use stock solution method

Derived From

Zinc Ethylenediaminetetraacetate (Zn-EDTA)

Premium chelated form provides superior stability and plant availability compared to zinc sulfate. The EDTA chelate protects zinc ions from precipitation and tie-up in alkaline soils.

Application Rates & Directions

Below are recommended rates for various applications. Zinc is immobile in plants, so deficiency appears on new growth first.

🌱 Soil Application

Crop Type Application Rate Notes
Vegetable Crops 4-12 lbs/acre or 2-5 oz/1000 sq ft Apply pre-plant or side-dress
Field Crops 4-12 lbs/acre or 2-5 oz/1000 sq ft Band application most efficient
Tree & Vine Crops 4-15 lbs/acre or 0.5-2 oz/inch trunk Apply to root zone
Ornamental Shrubs 2 tbsp (small) or 2 tbsp/inch diameter Work into soil
Turf 0.5 lb/1000 sq ft or 22 lbs/acre Water in thoroughly

🍃 Foliar Application

Crop Type Application Rate Spray Volume
Citrus Trees 1-2 lbs/100 gal Cover spray (avoid bloom)
Other Trees & Vines 1-2 lbs/acre 25 gal minimum
Vegetables & Field Crops 0.33-1.33 lbs/acre 25 gal minimum
Turf 1-4 oz/1000 sq ft Thorough coverage

💧 Hydroponics/Fertigation

System Method Target ppm Zn

Frequently Asked Questions
What are the signs of zinc deficiency in plants?

Zinc deficiency presents distinct symptoms on new growth first (zinc is immobile in plants):

  • Interveinal chlorosis: Yellowing between leaf veins on young leaves
  • Small, narrow leaves: Known as "little leaf" in trees
  • Shortened internodes: Creates rosette appearance with clustered leaves
  • Bronze or brown spots: Necrotic spots on leaves, especially in beans
  • Delayed maturity: Slow growth and poor fruit/seed development
  • White bud in corn: Young leaves emerge white or pale yellow

Most susceptible crops: Corn, rice, citrus, pecans, beans, and grapes. Deficiency is common in high pH soils (above 7.0), sandy soils, high phosphorus soils, and cool, wet conditions.

How does chelated zinc EDTA compare to zinc sulfate?

Chelated zinc EDTA offers significant advantages over zinc sulfate:

  • pH stability: Remains available up to pH 7.0 (zinc sulfate precipitates above pH 5.5)
  • 5-10× more efficient: Lower application rates needed for same effect
  • No soil tie-up: Protected from phosphate and carbonate reactions
  • Compatible mixing: Can be tank-mixed with most fertilizers and pesticides
  • Longer residual: Stays available for extended periods
  • Less phytotoxic: Gentler on plant tissues in foliar applications

While zinc sulfate is cheaper per pound, the superior efficiency of chelated zinc often makes it more economical per acre treated.

When and how should I apply zinc fertilizer?

Timing considerations:

  • Preventive: Apply pre-plant or at planting for susceptible crops
  • Corrective: Apply immediately when deficiency symptoms appear
  • Annual crops: Single application at planting usually sufficient
  • Perennials: Apply in early spring before bud break

Application methods (ranked by effectiveness):

  1. Banded soil: Most efficient - place 2-3" beside and below seed
  2. Foliar spray: Fast correction - apply to young leaves
  3. Broadcast soil: Less efficient - requires higher rates
  4. Seed treatment: Preventive for cereals
Can I use this product in hydroponics?

Yes, but use the stock solution method for safety.

Direct powder addition to reservoirs risks severe overdose because the amounts needed are extremely small (often less than 1 gram for a typical reservoir).

Stock Solution Method:

  1. Dissolve ½ cup (108g) in 1 gallon of water
  2. This creates a ~4,000 ppm zinc concentrate
  3. Add 1-3 teaspoons of stock per 100 gallons of reservoir
  4. Target 0.05-0.2 ppm zinc in final solution

⚠️ Warning: Zinc toxicity occurs above 0.5 ppm. Symptoms include bronze leaf discoloration and root damage. Always test and start with lower concentrations.
