High-content Chelated Iron + Acid Adaptability: Cost-effective Fast-acting Iron Supplement
EDTA chelated iron (Fe 13.3%, core advantage) features a chelation rate of ≥98%, pH 4.93 acidic property, and 200-mesh powder form. With a stable chelated structure, it is not a simple iron supplement, but a deep synergy of "high iron content + acid adaptability + high cost performance", avoiding the disadvantage of ordinary iron fertilizers being easily fixed in soil. It integrates multiple functions: fast iron supplementation, chlorosis correction, photosynthesis improvement, and convenient compounding. Suitable for various iron-demanding crops, especially acidic to neutral soils, it is a highly efficient iron product with outstanding cost performance.
1. Mutual Enhancement: Chelated Activity Combined with High Content Adopting high-quality chelation technology to form stable EDTA-iron complexes, ensuring EDTA chelated iron content reaches 13.3% and chelation rate ≥98%. Iron exists stably in an easily absorbable form and can be directly absorbed and utilized by crop roots without additional conversion. The 200-mesh brown powder has fine particle size and excellent dispersibility, dispersing quickly in water or soil without caking. Combined with high chelation rate, it effectively prevents iron from being fixed in soil, maximizes biological activity, achieves dual enhancement of "high-content locking + efficient absorption", and meets crops’ demand for large-scale iron supplementation.
2. Acid Adaptability: Precisely Matches Acidic Soils The product has a stable pH of 4.93, weakly acidic, adapting to acidic to neutral soil environments (pH 4.5–7.0). It precisely matches the physical and chemical properties of such soils, preventing iron from combining with phosphate and calcium ions in soil to form precipitates, completely solving the low utilization rate of ordinary iron fertilizers in acidic to neutral soils. The 200-mesh powder can evenly penetrate all soil layers, stably supplying iron in acidic fields, orchards, or neutral substrates in greenhouses, optimizing soil iron availability for targeted soil scenarios.
3. Fast Iron Supplementation: Chlorosis Correction and Growth Improvement 13.3% high-content EDTA chelated iron can be rapidly absorbed through roots and leaves to precisely supplement iron required by crops. As a core raw material for chlorophyll synthesis, iron quickly corrects iron-deficiency chlorosis, increases leaf chlorophyll content, enhances photosynthetic efficiency, and improves issues such as yellowing leaves, slow growth, and weak vigor caused by iron deficiency, rapidly restoring healthy crop growth and laying a foundation for high yield and quality.
4. High Compatibility: Easy Compounding and Wide Adaptability 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 fertilizer and pesticide efficacy. Its weakly acidic pH 4.93 suits most acidic to neutral soil cultivation systems without extra pH adjustment. Applicable via foliar spray, drip irrigation, and fertigation, it fits both large-scale field farming and intensive fruit, vegetable, and flower planting to meet iron needs of various crops.
5. Quality and Efficiency Improvement: Broad Adaptation and Cost Optimization Suitable for various iron-demanding crops including fruits, vegetables, flowers, and field crops, especially iron-sensitive crops such as strawberries, tomatoes, citrus, and corn. It prevents iron-deficiency chlorosis while improving crop quality and yield. The 200-mesh brown powder allows accurate weighing, storage, and transportation without caking. Combined with 13.3% high content, it achieves "low dosage, high effect", reduces iron waste, significantly improves fertilizer use efficiency, balances iron supplementation effect and planting cost control, meeting high cost-performance demands.
Expert Advice: Especially suitable for acidic to neutral soils and crop iron deficiency scenarios, particularly iron-sensitive crops. Can be applied alone or compounded with conventional fertilizers via foliar spray, drip irrigation, or fertigation. The 200-mesh powder dissolves completely without clogging pipes. Best iron supplementation effect is achieved when applied at early chlorosis stages or key growth periods. Adjust dosage as needed for precise iron supply, quality improvement, and yield increase.
