1、Characteristics of fused calcium magnesium phosphate fertilizer (FCMP
Fused calcium magnesium phosphate (FCMP) is a slow-release glass phosphate fertilizer. FCMP usually contains 12 %− 18 % of P2 O 5, and some nutrient elements such as Ca, Mg and Si required by plants.
2、Exchangeable Calcium/Magnesium Ratio Affects Phosphorus
Calcium and magnesium are two dominant cations in calcareous soils that undergo precipitation reactions with applied P fertilizers. Unlike Ca, the reactions of Mg with P have not been thoroughly studied.
3、A novel hierarchical structured calcium magnesium ammonium
In this work, a new slow-release fertilizer (SRF) of calcium magnesium ammonium polyphosphate (CMAPP) is constructed using unpurified wet-process phosphoric acid (WPA), discarded phosphorus tailings and urea.
4、Water soluble phosphate fertilizers for crops grown in calcareous soils
The current paradigm for phosphorus (P) fertilizers applied to calcareous soil is that almost entirely water soluble P fertilizers are efficient and sparingly soluble P fertilizers are not efficient P sources for crops.
Water
Calcium-magnesium phosphate fertilizer, also known as fused calcium-magnesium phosphate (fertilizer), is an aluminosilicate glass body containing phosphate (PO4 3-) without a clear molecular formula and molecular weight.
Interaction among Fertilizers (Compatibility)
When preparing fertilizer solutions for nutrigation , each component solubility must be considered in order to avoid possible precipitate . The following mixtures reduce solubility and form the following sedimentations.

In short, these fertilizers offer an efficient and effective way to supply two critical secondary macronutrients, promoting stronger growth, higher yields, and better quality produce in modern, precision agriculture and horticulture.

The Synergistic Effects of Different Phosphorus Sources
Phosphorus (P) application can enhance soil P availability and alter P fractions. However, the P accumulation and transformation of different P sources in low-phosphorus red soil remain unclear.
Fertilizer Compatibility
When mixing fertilizers, it is important to check fertilizer compatibility before application. If incompatible fertilizers are mixed, they form insoluble precipitations that can clog drip emitters and damage sprayers used to apply foliar fertilizers (Figure 1.).
Calcium-Magnesium-Phosphorus (CMP) is a water-soluble fertilizer primarily designed to provide essential nutrients for plant growth. It contains three key elements—calcium, magnesium, and phosphorus—which are critical for the development and health of plants.
Calcium is one of the essential macronutrients for plants. It plays a vital role in root development, cell wall formation, and disease resistance. Additionally, calcium enhances photosynthesis by improving light efficiency, making it indispensable for plant growth.
Magnesium is a micronutrient required for chlorophyll synthesis, energy metabolism, and protein production. It also promotes root growth and improves soil water retention. Thus, magnesium is equally important for healthy plant development.
Phosphorus, another macronutrient, significantly impacts plant growth, fruit quality, and stress resistance. It stimulates root expansion, enhances soil water retention, and boosts crop yields, underscoring its critical role in agriculture.
As a water-soluble fertilizer, CMP delivers a balanced blend of calcium, magnesium, and phosphorus, addressing the nutritional needs of plants efficiently. The optimized ratio of these elements ensures effective absorption while preventing excessive accumulation of calcium or magnesium ions in the soil, which could hinder plant growth.
CMP’s high solubility allows rapid uptake by plants, and its comprehensive nutrient profile supports various growth stages. These qualities have made it widely adopted in agricultural practices.
Key Considerations for Using CMP:
- Timing: Apply during active growth phases when nutrient demands are high. Avoid critical periods like flowering or fruiting to prevent disruption.
- Dosage and Concentration: Adjust application rates based on soil fertility and crop requirements. Excessive use may lead to nutrient imbalances.
- Complementary Fertilization: Combine with organic fertilizers or compound fertilizers to enhance nutrient synergy and soil structure.
- Environmental Protection: Prevent soil or water contamination by adhering to local regulations and eco-friendly practices.
CMP is a water-soluble fertilizer aimed at nourishing plants, not controlling pests. Responsible use, combined with other fertilizers and environmental safeguards, supports sustainable agricultural development.
