Main Applications of Chelated Magnesium EDTA-Mg: As a trace element nutrient for agriculture, forestry, animal husbandry, and other cash crops.
Usage:
a. Foliar Spray:
Chelated magnesium dissolves rapidly in water, making foliar spraying more effective. The optimal concentration for various crops is 800-2000 times the recommended dose, with frequent and light application.
b. Soil Topdressing:
Chelated magnesium can also be applied as a soil topdressing or with irrigation. When irrigating the soil, dilute the chelated magnesium 500-1000 times and apply with water. The dosage should be determined based on the severity of the crop’s deficiency.
Advantages of Using Chelated Magnesium:
a. Prevents and corrects magnesium deficiency symptoms in crops;
b. Chelated magnesium is suitable for crops with specific magnesium requirements;
c. Particularly suitable for acidic soils where magnesium deficiency is common.
Packaging: 25kg kraft paper bags or as per customer’s specifications.
Storage: This product should be stored in a cool, dry place (<30°C), well-ventilated, and shaded warehouse. Avoid mixing with alkaline substances or strong oxidants.
Magnesium is a secondary nutrient required for normal plant growth and development. It is involved in plant physiological reactions and the development of cell tissue structure. It is the main mineral component of chlorophyll and directly affects photosynthesis and the synthesis of sugars and proteins. It is crucial for plant growth, and its deficiency can cause irreparable harm.
Given the prominent role of magnesium in plant growth, the impact of magnesium deficiency on plant growth cannot be ignored. Magnesium deficiency can cause apples to fail to ripen properly, resulting in smaller fruits, poor coloration, and a lack of flavor. Magnesium deficiency can make young peach trees difficult to survive the winter, soybeans mature prematurely, and yields are low. Magnesium deficiency in citrus often leads to significant leaf drop and shoot dieback in late autumn, impacting normal growth and fruiting the following year, reducing fruit quality and yield. Therefore, studying plant growth under magnesium deficiency is crucial both from a physiological and economic perspective.
Magnesium is a component of chloroplast molecules and an activator of enzymes involved in photosynthesis and metabolism, facilitating the conversion of monosaccharides and thus playing a crucial role in carbohydrate metabolism. Magnesium ions play a crucial role in charge balance between the chloroplast stroma and the thylakoid stroma; they also act as catalysts for ATPase, among other functions.
Excessively low magnesium concentrations (e.g., treatment with ethylenediaminetetraacetic acid to chelate free magnesium ions) can hinder chlorophyll synthesis, ultimately resulting in a pale green leaf color. Symptoms include: initial yellowing of leaf edges, while the center of the leaf, with its denser veins, retains a certain degree of green. In severe cases, leaves may fall off, ultimately leading to the withering and death of the entire plant. Magnesium deficiency in crops reduces chlorophyll, weakens photosynthesis, hinders carbohydrate metabolism, and affects growth. Magnesium also plays a role in fat formation. When legumes are deficient in magnesium, the oil content of their seeds decreases. Chemical measurements show that crops with high phosphorus content also have high magnesium content, indicating that magnesium can promote phosphorus absorption. Crops that require high phosphorus also require high magnesium.
Magnesium is primarily found in young organs and tissues. As crops mature, most of the magnesium is transferred to the seeds. Magnesium ions activate various phosphomutases and phosphokinases during photosynthesis and respiration. Similarly, magnesium activates DNA and RNA synthesis. Magnesium is a component of chlorophyll synthesis. Magnesium deficiency prevents adequate chlorophyll synthesis. Severe magnesium deficiency can lead to brown spots and necrosis. Magnesium is a component of chlorophyll and an activator of many enzymes. It is the primary counterpart ion for hydrogen ions in photosynthetic phosphorylation.
Common magnesium fertilizers include MgSO4, magnesium sulfate, and magnesium chloride. In most cases, soil application is ineffective. To improve the effectiveness of magnesium fertilizers, mix them with organic fertilizers and apply them in strips or holes. EDTA-Mg is very stable and is effective in replenishing magnesium in soils, especially alkaline soils. Foliar spraying of magnesium fertilizers also has the disadvantage of being easily oxidized. Using a chelated magnesium fertilizer, such as EDTA-Mg, and spraying it multiple times can effectively prevent and treat magnesium deficiency. Free chelated magnesium (EDTA-Mg) treated with ethylenediaminetetraacetic acid facilitates plant absorption.
