Super phosphate SSP is a widely used phosphate fertilizer made by chemically reacting phosphate rock with sulfuric acid. This fertilizer contains about 12% to 14% phosphorus and is also rich in calcium and sulfur.

Single superphosphate is a widely used phosphate fertilizer made by chemically reacting phosphate rock with sulfuric acid. This fertilizer contains about 12% to 14% phosphorus and is also rich in calcium and sulfur. Single super phosphate appears in the form of white or off-white powder. It is a physiologically acidic fertilizer that can simultaneously provide the three elements of phosphorus, calcium and sulfur required for the growth and development of crops.

What are the functions of single super phosphate(SSP)?

Phosphorus is an important component of plant cell nucleic acids and cell membranes, and plays a vital role in plant growth and development. Calcium is an important component of plant cell walls and cell membranes, helping to improve plants’ disease resistance and ability to adapt to environmental changes. Super phosphate SSP can promote the development of plant root systems, improve the plant’s ability to absorb water and nutrients, promote flower bud differentiation, increase the number of flowers, and improve the plant’s stress resistance.

What are the precautions for using single super phosphate SSP fertilizer?

When using single Super phosphate SSP, you need to pay attention to the appropriate amount of fertilizer to avoid acidification of the soil. Do not mix it with alkaline fertilizer to avoid reducing fertilizer efficiency. Also, pay attention to the timing and method of fertilization to ensure that the fertilizer can be effectively absorbed by plants. Superphosphate is suitable for use as a base fertilizer, especially when applied before crop planting or sowing.

What is the production process of single super phosphate?

1.Crushing and grinding of phosphate rock: After crushing the phosphate rock to a certain particle size, grind it to increase the surface area of the phosphate rock and facilitate subsequent reactions.

2.Acidolysis reaction: Mix the ground phosphate rock and sulfuric acid in a certain proportion to carry out acidolysis reaction. During the reaction, calcium phosphate in the phosphate rock reacts with sulfuric acid to form superphosphate and calcium sulfate. The reaction equation is as follows: Ca3(PO4)2 + 3H2SO4 → 3CaSO4 + 2H3PO4

3.Ripening process: After the reaction is completed, the mixture is aged to separate the single super phosphate and calcium sulfate. Temperature and time need to be controlled during the curing process to ensure product quality and yield.

Which is better, diammonium phosphate or single super phosphate fertilizer?

Diammonium phosphate is effective as base fertilizer! First of all, consider the alkaline characteristics of the soil and pay attention to giving priority to diammonium phosphate or Super phosphate SSP. Because applying calcium magnesium phosphate fertilizer or phosphate rock powder to alkaline soil is basically ineffective. Diammonium phosphate and superphosphate are very effective. Diammonium phosphate is in granular form, which is beneficial to increasing the available phosphorus content of the soil. Apply superphosphate to soil with high phosphorus content. Superphosphate contains a certain amount of sulfuric acid, which is beneficial to the activation of active ingredients in the soil. Diammonium phosphate is effective as a base fertilizer!

What are the disadvantages of single super phosphate?

Super phosphate SSP is a type of phosphate fertilizer. Excessive use will lead to an increase in phosphorus content in wastewater and waste, thereby polluting the environment and causing adverse effects on the ecological environment.

Slowing of animal growth: Although superphosphate can promote animal growth, long-term and large-scale use will cause problems such as slowed animal growth, reduced diet, increased excrement, etc., thereby reducing breeding efficiency.

Poor synergistic effect with other additives: The synergistic effect of superphosphate with other additives is not ideal, sometimes leading to side effects.
