3、Characterization of Different Magnesium Fertilizers and Their Effect on

The results showed that, despite the differences between different Mg fertilizers, the same functional group peaks were recorded among them. F-Mg fertilizers had a low pH and low Mg purity, while S-Mg fertilizers had a high pH and high Mg purity.

Magnesium Fertilization Improves Crop Yield in Most Production Systems

Mg fertilizers were classified into two types: (1) slowly released (Mg-S) fertilizers including Mg oxide, Mg hydroxide, dolomite, Mg carbonate, and calcium-Mg phosphate, and (2) rapidly released (Mg-R) fertilizers including Mg sulfate, Mg chloride, and potassium Mg sulfate.

What kind of fertilizer is magnesium fertilizer? What are the magnesium

Commonly used magnesium fertilizers include magnesium sulfate, magnesium chloride, magnesite, dolomite, and magnesia phosphate fertilizer. In addition, organic fertilizers also contain a certain amount of magnesium.

Magnesium Fertilizers

Nova MagPhos is a nitrogen-free, free-flowing, fully soluble white crystalline fertigation fertilizer with high concentrations of pure magnesium, potassium and phosphorus to increase chlorophyll levels and boost plants in early growing stages.

Types and applications of magnesium fertilizer

Second, the type of magnesium fertilizer Magnesium fertilizer can be roughly divided into three categories according to its solubility, namely water-soluble solid magnesium fertilizer and liquid magnesium fertilizer.

Magnesium fertilizers ⋆ Agrochemistry

Magnesium fertilizers are mineral fertilizers or lime materials that meet the magnesium requirements of crops.

Role of magnesium fertilisers in agriculture: plant–soil continuum

Magnesium is involved in many physiological and biochemical processes; it is an essential element for plant growth and development and plays a key role in plant defence mechanisms in abiotic stress situations.

What Types Of Magnesium Fertilizer Are There? How To Apply?

Acidic soil, high soil and a large amount of phosphate fertilizer are prone to magnesium deficiency. The amount of magnesium fertilizer applied varies depending on the soil crop, and generally 15-25 kg of pure magnesium per hectare.

Magnesium Fertilizers, also known as magnesium additives or magnesium nutrients, are fertilizers used to supplement micronutrients essential for plant growth. They fall into a non-chemically synthesized category of fertilizers, primarily providing magnesium to promote healthy plant development.

Magnesium is one of the essential micronutrients required during plant growth. It plays a critical role in physiological processes such as photosynthesis, respiration, cell division, and hormone synthesis. Magnesium fertilizers enhance the absorption and utilization efficiency of major nutrients like nitrogen, phosphorus, and potassium, strengthening a plant’s growth potential and stress resistance. This, in turn, improves crop yield and quality.

Types of Magnesium Fertilizers

1. Organic Magnesium Fertilizers: These are derived from organic materials, such as animal manure or green manure, which naturally contain magnesium. Their advantages include widespread availability and low cost. they act more slowly and require extended periods to release magnesium.
2. Inorganic Magnesium Fertilizers: Chemically synthesized, examples include magnesium sulfate (MgSO₄) and magnesium chloride (MgCl₂). These provide rapid magnesium supplementation but are often more expensive and may pose environmental contamination risks if overused.

Agricultural Applications Magnesium fertilizers are widely used in grain crops (e.g., wheat, corn, rice), oilseed crops (e.g., soybean, cotton, peanut), vegetables, fruits, and orchards. For instance, gramineous crops like wheat and rice have high magnesium demands, while legumes and oilseeds require moderate magnesium levels to optimize yields and quality.

Application Methods

1. Basal Application: Magnesium fertilizers are evenly spread on the soil surface before plowing to increase soil magnesium concentration. Suitable for large fields.
2. Topdressing: Applied during crop growth based on soil conditions and crop needs. Methods include foliar spraying, root-side application, or hole application. Common for magnesium-intensive crops like corn and wheat.
3. Foliar Spraying: Diluted magnesium solutions are sprayed directly onto leaves for quick absorption. Effective for crops like wheat and corn.
4. Fertigation (Drip Irrigation): Magnesium is dissolved in water and delivered via drip irrigation systems to reduce nutrient loss and improve efficiency. Preferred for high-value crops and orchards.

Key Considerations

• Select Appropriate Formulations: Choose magnesium fertilizers based on crop requirements and soil conditions.
• Control Dosage: Excessive use may lead to soil acidification, salinization, or nutrient imbalances. Follow recommended application rates.
• Avoid Overapplication: Overuse can harm soil health and hinder the absorption of other nutrients.

As non-chemically synthesized fertilizers, magnesium products play a vital role in agriculture. Proper use of magnesium fertilizers boosts crop yields, enhances quality, and supports sustainable agricultural practices.
