Key Benefits of Calcium Magnesium Phosphate Fertilizer
Calcium magnesium phosphate fertilizer offers multiple advantages for modern agriculture:
- Provides long-lasting nutrient supply (3-6 months)
- Improves soil pH balance in acidic soils
- Enhances microbial activity in the soil
- Reduces phosphorus fixation in soil
- Suitable for organic farming systems
Application Recommendations
| Crop Type | Application Rate (kg/ha) | Application Method |
|---|---|---|
| Cereals (Wheat, Rice) | 300-400 | Broadcast before planting |
| Fruit Trees | 500-800 | Basal application in planting holes |
| Vegetables | 400-600 | Band application or side dressing |
| Legumes | 250-350 | Broadcast and incorporate |
Frequently Asked Questions
What is the best time to apply calcium magnesium phosphate fertilizer?
The optimal time is during soil preparation before planting. For perennial crops, early spring application is recommended when soil temperature reaches 10°C.
Can calcium magnesium phosphate fertilizer be used with other fertilizers?
Yes, it can be combined with most organic and chemical fertilizers. However, avoid mixing with highly acidic fertilizers as this may reduce effectiveness.
How does calcium magnesium phosphate fertilizer compare to regular phosphate fertilizers?
Calcium magnesium phosphate fertilizer releases nutrients gradually, prevents phosphorus fixation, and provides secondary nutrients (Ca and Mg) that most phosphate fertilizers lack.

Additional Technical Information
Calcium magnesium phosphate fertilizer works through gradual dissolution in soil moisture. The presence of calcium carbonate in the formulation buffers soil acidity while magnesium improves photosynthesis efficiency. This product is particularly effective in tropical soils where phosphorus fixation is a major concern.
The manufacturing process involves high-temperature fusion of phosphate rock with magnesium and calcium sources, resulting in a product with excellent physical properties and nutrient availability. Unlike water-soluble phosphates, calcium magnesium phosphate fertilizer minimizes nutrient leaching losses.
