High Chelated Manganese + Neutral Full-Scope Adaptation: Photosynthesis-Enhancing Fast-Acting Manganese Fertilizer
EDTA chelated manganese (Mn 12.7%, core advantage) features a chelation rate of ≥98%, neutral pH 6.57, and appears as a 200-mesh pink powder. Relying on a stable chelated structure, it achieves deep synergy of “high-capacity manganese retention + stable neutral efficacy + photosynthetic enzyme activation”, avoiding the disadvantage of ordinary manganese fertilizers being easily fixed by soil colloids. It integrates multiple functions: fast manganese supplementation, nutrient deficiency correction, enzyme activity activation, and convenient compounding. Suitable for various crops, especially manganese-sensitive ones, it is the preferred product for efficient manganese supplementation, quality improvement and yield increase.
1. Mutual Enhancement: Chelation Activity and High Content Synergy Using high-quality chelation technology to form a stable EDTA-manganese complex, ensuring EDTA chelated manganese content reaches 12.7% and chelation rate ≥98%. Manganese exists stably in an easily absorbable form and can be directly absorbed by crop roots without additional conversion. The 200-mesh pink powder has fine particle size and excellent dispersibility, dispersing quickly in water or soil without caking. Combined with the high chelation rate, it effectively prevents manganese fixation, maximizes biological activity, and adapts to different application methods, realizing dual enhancement of “high-capacity activity retention + efficient absorption” to meet crops’ demand for concentrated manganese supplementation.
2. Neutral Adaptation: Full Soil Compatibility The product has a stable pH of 6.57 (neutral), suitable for neutral to weakly alkaline soil (pH 5.5–8.0). It precisely matches the physicochemical properties of such soil, solving the industry pain point that manganese is easily fixed when soil pH > 6.5, avoiding precipitation from manganese binding to soil colloids, and ensuring long-term activity of manganese. The 200-mesh powder can evenly penetrate all soil layers, stably supplying manganese in neutral fields, orchards or weakly alkaline substrates in greenhouses, optimizing soil manganese availability for diverse planting scenarios.
3. Fast Manganese Supplementation: Deficiency Correction and Physiological Enhancement The 12.7% high-content EDTA chelated manganese is rapidly absorbed through roots and leaves, accurately supplementing manganese required by crops. As a core component of photosystem II in photosynthesis, manganese promotes chlorophyll synthesis, participates in photolysis of water, activates various enzymes such as superoxide dismutase, regulates reactive oxygen species balance, and reduces oxidative stress. It quickly corrects crop manganese deficiency symptoms including interveinal chlorosis in new leaves, leaf tip necrosis, stunted growth, and poor flowering and fruiting, improves manganese deficiency yellowing in solanaceous fruits, leafy vegetables and other crops, enhances photosynthesis and nutrient conversion efficiency, and quickly restores robust crop growth.
4. High Compatibility: Easy Compounding and Full-Scope Adaptation The product has excellent compatibility, can be mixed with most water-soluble fertilizers and pesticides without antagonism or precipitation, no separate preparation needed, and synergistically amplifies overall fertilizer and pesticide efficacy. The neutral pH 6.57 adapts to most planting processes without additional pH adjustment, suitable for foliar spray, drip irrigation, and fertigation. It meets the needs of large-scale field planting as well as intensive cultivation of fruits, vegetables, grain and oil crops, satisfying manganese supplementation for different crops.
5. Quality and Efficiency Improvement: Broad Adaptation and Cost Optimization Suitable for various manganese-demanding crops such as fruits, vegetables, grain and oil, and cash crops, especially manganese-sensitive crops like wheat, rice and sugar beets, as well as manganese-deficiency-prone crops including solanaceous fruits, melons and leafy vegetables. It prevents manganese deficiency, promotes nitrogen metabolism, strengthens cell wall mechanical strength, improves crop stress resistance and fruit quality, boosts full grain filling and increases 1000-grain weight. The 200-mesh pink powder facilitates accurate weighing, storage and transportation with low caking risk. Paired with 12.7% high content, it achieves “low dosage, high efficiency”, reduces manganese waste, significantly improves fertilizer utilization rate, balancing manganese supplementation effect and planting cost control.
Expert Advice: Especially suitable for neutral to weakly alkaline soils and manganese deficiency scenarios of various crops, particularly manganese-sensitive crops such as wheat, rice and sugar beets. 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 spraying effects at seedling and reproductive growth stages. Recommended for 2–3 consecutive applications at 7–10 day intervals, adjust dosage as needed to achieve precise manganese supplementation, quality improvement and income increase.
