1、Performance of phosphogypsum and calcium magnesium phosphate fertilizer

Calcium magnesium phosphate fertilizer and phosphogypsum obtained from a local fertilizer company were used as phosphorus additives for nitrogen conservation during composting.

2、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.

3、Impact of biochar, calcium magnesium phosphate fertilizer and spent

Calcium magnesium phosphate fertilizer (CaMgP) is a kind of multi-element fertilizer that can provide phosphorus (P), calcium (Ca), magnesium (Mg) and silicon (Si). Its aqueous solution is alkaline and can used as an acid soil amendment. CaMgP is cheap and widely used as a base fertilizer in China.

4、Insights on the additive formulation for the energy

In this study, a new method was proposed to determine the optimal addition amount of CaO and MgO to sludge, realizing the high phosphorus (P) availability and simultaneously reducing the melting point of the system for energy saving.

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.

Phosphorus fertilizer sources: What are the differences and which one

Are there alternatives to MAP, DAP, or TSP other than manure or biosolids? One additional product I have had questions about is Crystal Green. Crystal Green is composed of struvite, which is magnesium ammonium phosphate (MgNH₄PO₄·6H₂O).

以钙镁磷肥产品创新促进产业发展

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.

Preparation of Multifunctional Fused Magnesium Phosphate Fertilizer

These inferior ores with high silicon and magnesium contents are favorable raw materials to produce fused magnesium phosphate fertilizer (FMP) for the crop growth.

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.

What are the differences between Calcium Phosphate Monobasic and

Calcium Magnesium Phosphate Fertilizer has the ability to supply crops with calcium, silicon, and other elements, making it more effective when applied to calcium-loving legumes and crops that require silicon, such as rice and wheat.

In agricultural production, organic calcium-magnesium phosphate fertilizer is a commonly used product, supplying essential elements like calcium, magnesium, and phosphorus for plant growth. due to environmental concerns and resource limitations, there is growing interest in finding alternatives. The following options are worth considering:

1. Organic Fertilizers: These natural fertilizers, such as animal manure, compost, and green manure, are rich in organic matter and nutrients. They provide comprehensive nutrition to plants while improving soil structure and quality. Organic fertilizers enhance soil’s water-retention and nutrient-holding capacity, fostering healthier plant growth.

2. Biochar: Produced from biomass (e.g., crop residues or animal waste) through high-temperature pyrolysis under oxygen-limited conditions, biochar is a black or brown solid material. Its high surface area, porous structure, and stable chemical properties improve soil physical and chemical traits, boosting water and nutrient retention. This, in turn, supports plant development.

3. Phosphate Fertilizers: Inorganic phosphate fertilizers, such as potassium dihydrogen phosphate and monoammonium phosphate, deliver essential phosphorus. While phosphorus is vital for plants, excessive use can cause soil acidification and water eutrophication. Careful dosage control is critical to minimizing environmental risks.

4. Micronutrient Fertilizers: These fertilizers supply trace elements like boron, zinc, manganese, and iron, which are crucial for plant growth but often scarce in soils. When applying micronutrient fertilizers, selecting appropriate types and avoiding overapplication is key to preventing toxicity or imbalance.

5. Microbial Fertilizers: Containing beneficial microorganisms like Rhizobia (nitrogen-fixing bacteria), these fertilizers enhance soil nitrogen levels by converting atmospheric nitrogen into usable forms. Microbes also accelerate organic matter decomposition and nutrient cycling, promoting healthier soil ecosystems.

6. Chelated Micronutrient Fertilizers: These fertilizers bind micronutrients (e.g., chelated copper, zinc) to ligands via chelation, improving stability and uptake efficiency. Selecting suitable chelating agents and controlled dosages is essential to avoid environmental harm or crop damage.

substituting organic calcium-magnesium phosphate fertilizer requires evaluating soil conditions, crop needs, and ecological impacts. Organic fertilizers, biochar, phosphate fertilizers, micronutrient supplements, microbial products, and chelated micronutrients all serve as viable alternatives. their effective use depends on tailored application strategies and balanced combinations based on specific contexts.
