[Calcium Magnesium Phosphate Fertilizer]Calcium Magnesium Phosphate Fertilizer Chemical Formula Calcium Magnesium Phosphate Fertilizer Function and Use
Calcium Magnesium Phosphate Fertilizer is a raw material prepared with phosphate rock and magnesium silicate minerals. It is melted at 1350~1500 C in an electric furnace, blast furnace or open hearth, and the melt is quenched with water to form a vitreous material with a particle size of less than 2 mm, which is dried and ground to become a product. Calcium-magnesium phosphate fertilizer, also known as fused calcium-magnesium phosphate (fertilizer), is an aluminosilicate glass body containing phosphate (PO4 3-). The main components include Ca3(PO4)2, CaSiO3, MgSiO3. It is a multi-element fertilizer. The aqueous solution is alkaline, which can improve acidic soil. It is very effective as a base fertilizer when cultivating large seedlings, and plants can slowly absorb the required nutrients.

The Function and Use of Calcium Magnesium Phosphate Fertilizer
Calcium Magnesium Phosphate Fertilizer is gray-green or gray-brown powder with a phosphorus content of 12 %～18%, the main component is α-Ca3(PO4)2 which is soluble in citric acid, and also contains elements such as magnesium and a small amount of silicon. Magnesium is beneficial to the formation of chlorophyll (the important components of chlorophyll molecules are C55H72O5N4Mg and C55H70O6N4Mg), and silicon can promote the growth of crop fibrous tissue, so that plants have better ability to prevent lodging and pests. It works well as a base fertilizer when cultivating large seedlings, and plants can slowly absorb the nutrients they need.
Application method of calcium magnesium phosphate fertilizer
(1) It is most suitable for deep application of basal fertilizer. After calcium magnesium phosphate fertilizer is applied to the soil, phosphorus can only be dissolved by weak acid, and it can only be used by crops after a certain transformation process, so the fertilizer effect is slow and it is a slow-acting fertilizer. Generally, combined with deep ploughing, the fertilizer is evenly applied to the soil, and it is mixed with the soil layer to facilitate the dissolution of soil acidity and the absorption of crops.
(2) Mix with more than 10 times of high-quality organic fertilizer for composting for more than 1 month. The composted fertilizer can be used as base fertilizer, seed fertilizer, or dipped in seedling roots.
