What is triple super phosphate TSP fertilizer? How to determine real TSP and fake TSP? How to apply TSP to the fruits? in thei article you will find the answer.

Triple super phosphate, also known as TSP, is a fertilizer widely used in agricultural production. It contains high concentrations of phosphorus and calcium and is easily decomposed in the soil and can be directly absorbed and utilized by plants.

What is triple super phosphate TSP used for?

As a fertilizer, triple super phosphate TSP can provide nutrients needed by plants and promote plant growth and development. Applying a layer of triple super phosphate(TSP) to the seeds can not only provide the seeds with necessary nutrients, but also increase the germination rate and survival rate through sterilization.

What is the difference between superphosphate and TSP?

There is not much difference in properties between TSP and its main component is monocalcium phosphate. But the TSP dosage is less than that of ordinary phosphate fertilizer. Triple super phosphate TSP does not contain impurities such as gypsum. The available phosphorus content for crops to absorb and utilize can reach 40 to 50%, which is 2 to 3 times higher than ordinary super phosphate. Therefore, this fertilizer is also called double superphosphate or triple super phosphate TSP, or triple super phosphate fertilizer for short. Although it is called “three ingredients”, it does not contain three elements: N-P-K. Ternary fertilizer refers to a compound fertilizer containing three elements: nitrogen, phosphorus and potassium.

How to use super phosphate TSP as a base fertilizer?

TSP is a kind of phosphate fertilizer, mainly used as base fertilizer. Phosphorus ion is easily fixed in the soil. In order to improve the utilization rate, triple super phosphate fertilizer is often mixed with organic fertilizer. Generally, 4 tons of organic fertilizer and 50 kilograms of triple super phosphate are used per acre. As a base fertilizer, it can be used for soil preparation after spreading, which can continuously provide a large amount of phosphorus, calcium and sulfur for crop growth.

How does superphosphate improve land quality?

TSP can gradually decompose multiple phosphate ions in the soil, increase the concentration of phosphate ions in the soil, increase the absorption rate of these elements by plants, and at the same time reduce the pH value of the soil, helping to maintain the acidic level of the soil. .

How to use TSP as a foliar fertilizer?

TSP can also be used as a foliar fertilizer. Use 2 to 3 pounds of superphosphate per acre and add an appropriate amount of water to dissolve it. After standing for 24 hours, take the above clear solution as a foliar fertilizer and mix it with 100 pounds of water for spraying. , can improve the photosynthetic ability of leaves, making the leaves darker green and thicker, the root system more developed, and the resistance to cold and drought stronger.

What plants are suitable for growing with TSP?

When planting tomatoes, peanuts, eggplants, cucumbers, rape, cauliflower, beans and other plants with flowers and fruits, it is necessary to apply more phosphorus-containing inorganic salts. Other plants suitable for triple super phosphate are as follows

1.Vegetables: such as tomatoes, cucumbers, beans, peppers, eggplants, beans, etc.

2.Fruit trees: such as apples, pears, peaches, plums, pomegranates, citrus, etc.

3.Cereals: such as corn, wheat, rice, etc.

4.Oil crops: such as peanuts, soybeans, rapeseed, cottonseed, etc.

How to make triple super phosphate granular fertilizer?

Step1: Triple super phosphate fertilizer Granulation

Triple super phosphate raw materials, that is, TSP powder, are added to the drum of the TSP granulator for rotation. The material is added to the drum granulator through the feed port, and the drum starts to rotate driven by the motor, bringing the material from the feed end to the inside of the machine. Under the action of high-temperature steam and binder, pellets begin to form inside the granulator. , the pellet further becomes larger during the tumbling process.

Step2: TSP Drying

After the Triple super phosphate particles are granulated from the drum, they enter the drum dryer through the belt conveyor. Hot air is blown into the drum from the air inlet of the dryer. After heat exchange and endothermic vaporization of the material, the moisture in the Triple super phosphate particles evaporates. , and then discharged by the exhaust system. TSP materials are constantly rubbing, turning and mixing with each other. These movements make the temperature distribution of the material more uniform, and the moisture in the material is easier to volatilize.

Step3: TSP Cooling

The material enters the drum cooler after being fully dried. The purpose of cooling is to increase the strength of the particles and prevent moisture from re-entering the Triple super phosphate TSP fertilizer particles. The cooling method is air cooling, and the direction of material movement is opposite to the direction of the blower. , fully cool to the temperature required by the process during the rolling process, and then enter the coating machine for coating

Step4: TSP Screening

Since the Triple super phosphate TSP fertilizer production process will produce overly large particles and undersized powders, in order to achieve maximum resource utilization, both large particles and fine powders will be returned to the system for re-granulation. The rear end of the cooler and the front end of the coating machine will be equipped with a drum or vibrating screening device to ensure that large particles are returned to the crusher for secondary crushing, and particles that are too small are returned to the granulator for re-granulation.

Step5: TSP Coating

The fully cooled and screened Triple super phosphate TSP fertilizer can enter the drum coating machine for coating. With the addition of anti-caking agent and coating oil, the outer layer of the Triple super phosphate TSP fertilizer will be covered with a protective layer, which can effectively prevent the fertilizer from solidifying and It is loose, the strength of the granules can reach 20 N, and the storage time can be up to half a year without loosening. In this way, the finished TSP fertilizer is completed.
