1、The power of magnesium: unlocking the potential for increased yield

Influence of calcium and magnesium based fertilizers on fungal diseases, plant growth parameters and fruit quality of three varieties of tomato (Solanum lycopersicum).

2、Frontiers

Our analysis corroborated that Mg fertilization enhances crop performance by improving yield or resulting in favorable physiological outcomes, providing great potentials for integrated Mg management for higher crop yield and quality.

3、Magnesium

Magnesium (Mg) deficiency can significantly limit crop yield and quality. Separate application of straight Mg fertilizer is unattractive because of additional labor costs. Meanwhile, bulk blending Mg with other macronutrient fertilizers is also a suboptimal solution because bulk blended fertilizers often yield poor nutrient distributions.

Optimizing Potassium Fertilization Combined with Calcium–Magnesium

Alkaline fertilizers demonstrate significant potential in mitigating rice cadmium (Cd) accumulation, yet the combined effects of calcium–magnesium phosphate (CMP) with potassium (K) fertilizer types and split application strategies remain unclear.

Combined Application of Calcium

This study indicated that maize could dissolve the insoluble P fertilizer, i.e., calcium-magnesium phosphate fertilizer, by secreting succinate and T-aconitate in a calcare-ous soil.

Calcium and Magnesium in food production C

Calcium and Magnesium sources available to farmers Farmers cannot profitably grow food without calcium and magnesium. sium are secondary nutrients for plants. Although these nutrients can’t be found as free elements in nature, they are some of the most

Fused calcium magnesium phosphate (FMP) is an alkaline mineral fertilizer riched in P, Ca, Mg, Si and other nutrients. It can supply trace elements needed by plants, relieve acidic soil, effectively reduce heavy metal pollution and improve crop nutrition and quality.

Calcium and magnesium: secondary nutrients of prime importance

The drive for ever higher crop yields is shifting the focus onto secondary nutrients such as calcium and magnesium. In this article, we look at the role of magnesium and calcium in crop nutrition and the main fertilizer product options.

Role of calcium nutrition in plant Physiology: Advances in research and

Calcium fertilizers play a key role in improving acidic soils and facilitating sustainable crop production. Liming is a key mechanism by which calcium fertilizers mitigate soil acidity.

Effect of Combined Application of Calcium Magnesium Phosphate

Conclusion In conclusion, calcium-magnesium-phosphate fertilizer with lime significantly reduced the risk of Cd contamination in rice grain, which increased the bioavailable Si, Ca and Mg while increasing soil pH and reducing the available Cd, thus inhibiting the Cd accumulation in rice.

Calcium-magnesium-phosphate fertilizer, also known as ammonium phosphate, is a compound fertilizer containing the three primary nutrients: nitrogen (N), phosphorus (P₂O₅), and potassium (K₂O). In agricultural production, rational application of this fertilizer is critical for improving crop yields and quality. Below are guidelines for effective use:

1. Types and Characteristics of Calcium-Magnesium-Phosphate Fertilizers

• Diammonium Phosphate (DAP): A high-concentration compound fertilizer containing 0.42% nitrogen, 38% phosphorus (P₂O₅), and 54% potassium (K₂O). Suitable for various crops, especially phosphorus-loving plants like corn, cotton, and tobacco.
• Superphosphate: Contains 60%-70% phosphorus (P₂O₅), 30%-40% potassium (K₂O), and 0.3%-0.5% nitrogen. Ideal for crops with high phosphorus demands, such as rice, rapeseed, and peanuts.
• Triple Superphosphate: Comprised of 70%-80% phosphorus (P₂O₅), 15%-25% potassium (K₂O), and 0.5%-1% nitrogen. Best for phosphorus-sensitive crops like tea, coffee, and cocoa.
• Calcium Nitrate: Contains 20%-25% nitrogen, 0.5%-1.5% phosphorus (P₂O₅), 0.5%-1.5% potassium (K₂O), and 2%-6% potassium. Suitable for nitrogen-demanding crops like soybeans, wheat, and corn.

2. Application Methods

• Base Application: Spread evenly over soil before planting or sowing, then incorporate into the soil. Suitable for large-scale fertilization to ensure uniform distribution.
• Topdressing: Apply during crop growth by dissolving the fertilizer in water for irrigation or direct root application. Effective for targeted nutrient supplementation without waste.
• Foliar Spraying: Dissolve the fertilizer in water and spray onto leaves. Best for crops with fast nutrient absorption and low sensitivity to concentration, such as leafy vegetables.

3. Dosage Recommendations

• General Guideline: Apply 20–50 kg per mu (approx. 0.067 hectares) of land. Adjust based on soil fertility, crop type, and goals.
• Principle: Follow a "small doses, multiple applications" approach to avoid overuse, resource waste, or environmental pollution.

4. Precautions

• Avoid Alkaline Mixing: Do not mix with alkaline substances (e.g., lime), as this causes precipitation and reduces efficacy.
• Safety Measures: Wear protective gear (gloves, masks) to prevent skin/eye contact. Store out of reach of children and pets to avoid accidental ingestion or injury.

5. Application Timing and Effects

• Yield Increase: Enhances phosphorus uptake, promoting growth and increasing yields by 10%–20% (studies show).
• Quality Improvement: Strengthens disease resistance, boosts photosynthesis, and improves fruit sugar content.

Calcium-magnesium-phosphate fertilizer is a versatile nutrient source in agriculture. For optimal results, tailor its use to crop types, soil conditions, and application methods. Proper management ensures efficient nutrient utilization and healthy crop development.

Note: Adjust application details (e.g., dosage, timing) based on local agricultural practices and soil tests.
