1、钙镁磷肥（矿物质元素）_百度百科

钙镁磷肥又称熔融含镁磷肥fused calcium-magnesium phosphate (fertilizer) ，是一种含有磷酸根（PO43-）的硅铝酸盐玻璃体。 主要成分包括Ca3（PO4）2、CaSiO3、MgSiO3。

2、Calcium Magnesium Phosphate Fertilizer (CMP)

Calcium Magnesium Phosphate Fertilizer (CMP), chemically termed Fused Calcium-Magnesium Phosphate, is a glassy slow-release fertilizer produced by high-temperature fusion (1,350-1,500°C) of phosphate rock and magnesium silicate minerals.

3、Combined Application of Calcium

Combined application of inorganic phosphorus with calcium-magnesium phosphate fertilizer increased the utilization rate of calcium-magnesium phosphate fertilizer.

Magnesium

In this study, we explored the use of different Mg compounds for co-granulation with commercial mono-ammonium phosphate (MAP), using a disc granulator in the laboratory.

Calcium

In the current study, we examined the combined effect of organic fertilization and PGPR inoculants on soil fertility, plant growth, nutrient content, and secondary metabolite production (acemmanan and total phenolic compounds (TPCs)) of Aloe vera plants.

Understanding Plant Nutrition: Fertilizers And Macronutrients

In this article, we will focus on macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium and sulfur) supplied by water-soluble fertilizers. We will discuss macronutrient sources, fertilizer formulations and the application of fertilizer to the crop.

Types of Fertilizers Based on Chemical Composition and Their Use in

Calcium Nitrate – A nitrogen and calcium fertilizer that helps prevent blossom-end rot in fruits. Magnesium Sulfate (Epsom Salt) – A magnesium and sulfur fertilizer, often used for crops like tomatoes. Ammonium Sulfate – A source of nitrogen and sulfur, often used on crops needing these nutrients.

How fertilizer is made

Calcium is obtained from limestone, which contains calcium carbonate, calcium sulphate, and calcium magnesium carbonate. The magnesium source in fertilizers is derived from dolomite.

What Types of Fertilizers Should I Use to Improve Fruit yield

The mid-season is the ideal time to focus on fertilizers high in potassium and balanced with calcium and magnesium. Fertilizers like Monopotassium Phosphate (MKP), Potassium Sulfate, and Cal Mag are excellent choices.

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.

Calcium-magnesium-phosphate fertilizer with medium and micronutrients is a type of fertilizer primarily composed of phosphorus (P), calcium (Ca), potassium (K), and magnesium (Mg). Its main function is to provide essential nutrients for plant growth, promoting development and enhancing crop yield and quality.

Key Components

The fertilizer’s primary ingredients include calcium dihydrogen phosphate (Ca(H₂PO₄)₂) and ammonium phosphate (NH₄H₂PO₄), both of which are core components of phosphate fertilizers. Additionally, it contains significant amounts of calcium (Ca), magnesium (Mg), and potassium (K). These elements play critical roles in plant cell division, elongation, maturation, photosynthetic efficiency, and overall productivity.

Production Process

1. Raw Material Preparation: Phosphate rock, limestone, dolomite, magnesium sulfate, and other raw materials are crushed and ground into fine powders.
2. Batching: Raw materials are mixed in specific proportions according to production requirements.
3. Smelting: The mixed materials are heated in a furnace at high temperatures, where phosphorus, calcium, magnesium, and other elements react with oxygen to form compounds.
4. Crystallization: The molten mixture is cooled and transferred to a crystallizer, where centrifugal force separates solid substances from the liquid.
5. Filtration: Impurities are removed from the precipitated solids.
6. Drying: The filtered material is dried to reduce moisture content.
7. Packaging: The dried product is packaged as finished calcium-magnesium-phosphate fertilizer.

Advantages

1. Balanced Nutrient Content: Provides moderate levels of nutrients, avoiding soil salinization caused by excessive fertilization.
2. High Nutrient Uptake: Phosphorus, calcium, and magnesium are readily absorbed by plants, improving nutrient utilization efficiency.
3. Wide Adaptability: Suitable for various soil types and resistant to environmental fluctuations.
4. Yield Enhancement: Consistently boosts crop yields.
5. Eco-Friendly: Generates minimal waste during production, reducing environmental impact.

Calcium-magnesium-phosphate fertilizer with medium and micronutrients is a high-quality agricultural input. It supplies essential nutrients, enhances crop growth, and improves yield and quality while offering environmental benefits. Widely used in farming, it combines productivity and sustainability.
