2、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.
3、Combined Application of Calcium
To improve soil P fertility and maintain crop yield, large amounts of P fertilizers were applied (Withers et al. 2014). However, P fertilizer is mostly obtained from mined high-grade phosphate rock, which is a limited and non-renewable resource.

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.
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.

Is Calcium-Magnesium Phosphate Fertilizer a Compound Fertilizer? Why? Calcium-magnesium phosphate fertilizer is an important chemical fertilizer containing elements such as phosphorus, calcium, and magnesium. It is classified as a compound fertilizer because it contains multiple nutrient elements that can satisfy the various nutritional requirements of plant growth.
First, let us understand what a compound fertilizer is. A compound fertilizer is a type of fertilizer that contains two or more primary nutrient elements, typically including major elements like nitrogen (N), phosphorus (P), and potassium (K), along with other trace elements. The main function of compound fertilizers is to provide essential nutrients for plant growth while also supplying auxiliary nutrients, such as microelements.
Calcium-magnesium phosphate fertilizer contains three primary nutrient elements: phosphorus, calcium, and magnesium, all of which are indispensable for plant growth. Phosphorus acts as the "energy source" for plants, participating in many critical metabolic processes such as photosynthesis and respiration. Calcium is a vital component of plant cell walls, helping maintain cellular structural stability. Magnesium serves as a "catalyst" for plant growth, regulating the activity of numerous enzymes. these three elements in calcium-magnesium phosphate fertilizer are crucial for plant development and growth.
The reason calcium-magnesium phosphate fertilizer is termed a compound fertilizer lies in its formulation, which includes multiple nutrient elements. These elements complement each other, enhancing the absorption and utilization efficiency of nutrients by plants. For example, phosphorus can promote the absorption of calcium, thereby increasing calcium’s effectiveness; similarly, calcium can enhance magnesium absorption, improving magnesium’s availability. Additionally, trace elements in the fertilizer can interact synergistically with other nutrients to amplify their effects.
In agricultural production, calcium-magnesium phosphate fertilizer improves crop yield and quality. It provides abundant phosphorus, calcium, and magnesium, meeting plants’ nutritional needs. Meanwhile, its trace elements help plants resist pests and diseases, boosting stress resistance. Thus, this fertilizer holds significant practical value in agriculture.
calcium-magnesium phosphate fertilizer is not suitable for all crops. Different crops have varying nutrient demands, so the appropriate fertilizer variety must be selected based on crop characteristics. For instance, grain crops like rice and wheat require higher phosphorus levels, making high-phosphorus formulations preferable; whereas economic crops like cotton and soybeans need relatively less phosphorus, so low-phosphorus varieties are more suitable. soil conditions affect the fertilizer’s efficacy, so rational application should be guided by soil test results.
calcium-magnesium phosphate fertilizer is an important chemical fertilizer containing multiple nutrients essential for plant growth. As a compound fertilizer, it supplies key nutrients and enables synergistic interactions between elements. While beneficial for improving crop yields and quality, its use should be tailored to crop types and soil conditions through proper selection and formulation.
