Fused phosphate fertilizers and the preeminent properties brought to crops

Along with nitrogen fertilizer, potassium fertilizer, phosphate fertilizer is one of the inorganic fertilizers commonly used in cultivation to provide nutrients and promote plant growth. Currently, there are two types of phosphate fertilizers: natural phosphate fertilizers and processed phosphate fertilizers, in which high nutrient content must include fused phosphate fertilizers. So, fused phosphate fertilizer What is it, and what are its advantages? Let’s find out all through the article below.

  1. What is Fused Phosphate?

In simple terms, fused phosphate fertilizer is a type of phosphate fertilizer processed by heat.

Specifically, this fertilizer is produced by melting apatite or phosphate ores along with some additives containing silicon and magnesium. It is then cooled suddenly with water to keep it amorphous.

Fused phosphate fertilizer is known by many other names such as calcium-magnesium phosphate fertilizer or vitreous phosphate fertilizer.

The characteristics of fused phosphate fertilizers are gray or gray, slightly soluble in water. However, in the soil environment and secretions from the roots of plants, this fertilizer is up to 98% soluble.

  1. Classification of fused phosphate fertilizers on the market

There are two most popular types of fused phosphate fertilizers on the market today, granular and fine powdered phosphate fertilizers, both of which have the following characteristics:

  • Color: white gray, black ash or green ash
  • Formula: Ca3(PO4)3
  • pH from 8 to 8.5, high alkalinity, suitable for alkaline soil or infertile soil, soil with high slope
  • Properties: insoluble in water, but soluble in the resin secreted by the roots, containing 2% citric acid.
  • Chemical composition: 17% P2O5, 14% MgO, 26% CaO, 24% SiO2, and many other trace elements such as Fe, Cu, Mn, …
  • Usage: used as a primer before planting, buried deep in the soil, do not mix with water to irrigate plants directly

  1. Advantages of fused phosphate fertilizers

From the composition, it can be seen that the fused phosphate fertilizer contains many essential nutrients useful for plants. However, it is not only possible, let’s take a look at the outstanding properties of fused phosphate fertilizers.

Firstly, fused phosphate fertilizer has a pH of 8 – 8.5, so it has the highest alkalinity of all phosphate fertilizers available on the market. Therefore, this fertilizer has the ability to reduce acidity very effectively, but most of the soil in our country has an acidic reaction due to low pH.

If you intend to plant on acidic or alkaline soils, use a fused phosphate fertilizer as a deep fertiliser before planting.

Second, fused phosphate fertilizers are very difficult to dissolve in water but are almost completely soluble in the root fluid medium. Therefore, this fertilizer will slowly affect the soil, providing nutrients for the plants to help promote the environmentally friendly re-growth process.

Besides, the water-soluble nature of this fertilizer also makes it easier for farmers to store feces. You also do not need to worry about the stools melting or dissolving even when in a place with high humidity.

Third, fused phosphate fertilizer is suitable for many different crops thanks to its diverse nutrient supply effect. In particular, it must be mentioned that easily digestible sources of calcium, magnesium and silicon not only improve yield but also bring good quality of agricultural products, disease resistance for plants.

  1. Instructions for using fused phosphate fertilizers in agriculture

To maximize the advantages of fused phosphate fertilizers in cultivation, you need to keep in mind the following notes in use:

  • Used to fertilize plants before planting, can be combined with decayed manure to increase the efficiency of soil improvement.
  • Suitable for fruit trees, perennial industrial plants, legumes, etc., on acidic soils or infertile soils.
  • Do not use fused phosphate fertilizers for slightly alkaline soils, saline soils or neutral alluvial soils
  • Insoluble with water for direct irrigation of plants

On the market today, there are many units providing fused phosphate fertilizers for farmers. However, the two most reliable companies are Van Dien Fused Phosphate Joint Stock Company and Lam Thao Superphosphate and Chemical Joint Stock Company.

Wish you have a bountiful harvest when accompanied by melted phosphate fertilizer!
