High Chelated Zinc + Neutral Full-Scenario Adaptation: Special Fertilizer for Rapid Zinc Supplementation
EDTA chelated zinc (Zn 14.7%, core advantage) features a chelation rate of ≥98%, neutral pH of 6.64, and appears as 200-mesh white powder. Relying on a stable chelate structure, it achieves deep synergy of “high zinc retention + stable neutral efficacy + broad-spectrum adaptation”, avoiding the drawback of ordinary zinc fertilizers being easily fixed by soil colloids. It integrates multiple functions including rapid zinc supplementation, nutrient deficiency correction, growth promotion, fruit retention, and convenient compounding, suitable for various crops, especially zinc-sensitive ones, making it a preferred product for efficient zinc supplementation.
1. Mutual Enhancement: Synergy of Chelated Activity and High Content Using high-quality chelation technology to form a stable EDTA-zinc complex, ensuring EDTA chelated zinc content reaches 14.7% and chelation rate ≥98%. Zinc exists stably in an easily absorbable form and can be directly absorbed and utilized by crop roots without additional conversion. The 200-mesh white powder has fine particle size and excellent dispersibility, dispersing quickly in water or soil without caking. Combined with high chelation rate, it effectively prevents zinc fixation, maximizes biological activity, realizes dual empowerment of “high-content retention + efficient absorption”, and meets crops’ demand for concentrated zinc supplementation.
2. Neutral Adaptation: Compatibility with All Soils The product has a stable pH of 6.64 (neutral), suitable for neutral to slightly alkaline soils (pH 5.5–8.0). It precisely matches the physicochemical properties of such soils, avoiding zinc precipitation caused by binding with soil colloids, completely solving the low utilization rate of ordinary zinc fertilizers in neutral to slightly alkaline soils. The 200-mesh powder can evenly penetrate all soil layers, stably supplying zinc in neutral fields, orchards, or slightly alkaline substrates in greenhouses, optimizing soil zinc availability for diverse planting scenarios.
3. Rapid Zinc Supplementation: Deficiency Correction and Growth Improvement 14.7% high-content EDTA chelated zinc is quickly absorbed through roots and leaves, accurately supplementing zinc—a key trace element for crop growth. It promotes nutrient metabolism and flower bud differentiation, rapidly correcting zinc-deficient little leaf disease and poor fruiting. It enhances photosynthesis, alleviates stunted growth, weak vigor, and low fruit setting caused by zinc deficiency, quickly restoring healthy crop growth for high yield and quality.
4. High Compatibility: Easy Compounding and Full-Scenario Adaptation The product has excellent compatibility, can be mixed with most water-soluble fertilizers and pesticides without antagonism or precipitation, requiring no separate preparation and synergistically improving overall fertilization and pesticide efficacy. Its neutral pH of 6.64 fits most planting processes without pH adjustment, supporting foliar spray, drip irrigation, and fertigation. It suits large-scale field crops as well as intensive fruits, vegetables, grains, and economic crops, meeting zinc needs of various plants.
5. Quality and Efficiency Improvement: Broad Adaptation and Cost Optimization Suitable for zinc-requiring crops including fruits, vegetables, grains, and cash crops, especially zinc-sensitive ones like corn and cotton. It prevents zinc deficiency, promotes flowering and fruiting, and boosts crop yield and quality. The 200-mesh white powder allows accurate weighing, storage, and transportation without caking. Combined with 14.7% high content, it achieves “low dosage, high effect”, reduces waste, significantly improves fertilizer use efficiency, balances zinc efficacy and planting costs, meeting cost-effective needs of large-scale cultivation.
Expert Advice: Especially suitable for neutral to slightly alkaline soils and zinc-deficient conditions of various crops, particularly zinc-sensitive crops such as corn and cotton. Can be applied alone or mixed with conventional fertilizers via foliar spray, drip irrigation, or fertigation. The 200-mesh powder dissolves completely without clogging pipes; better zinc supplementation and growth promotion are achieved at key growth stages such as seedling and flowering stages. Dosage is recommended to be adjusted as needed for precise zinc supply, quality improvement, and income increase.

Application Suggestion: This product is suitable for foliar spray, drip irrigation, and fertigation. It can be mixed with non-strongly alkaline pesticides and fertilizers, and is strictly prohibited from mixing with strongly alkaline substances such as lime. For foliar spray, dilute 1000–2000 times and apply before 10 AM or after 4 PM on sunny days, spraying 2–3 times at 7–10 day intervals. For drip irrigation/fertigation, dilute 800–1500 times and apply evenly with irrigation water. It is recommended to use within 8 hours after dissolution to ensure zinc ion activity.
