Historical Development
In ancient farming, fertilizers were mostly obtained from plant ash and human and animal feces. Later, knowledgeable people discovered the effect of minerals. Fertilizer Soluble Ammonium Polyphosphate SAP was born to meet the needs of modern agriculture. The process was simple at first, but it has become more and more sophisticated and helps to increase production.
Product Overview
Fertilizer Soluble Ammonium Polyphosphate SAP is mostly in the form of granules or powders, white or slightly yellow, soluble in water, containing nutrients such as phosphorus and nitrogen, which can provide energy for crop growth, promote root growth and strengthen seedlings, and increase their resistance to adversity.
Physical & Chemical Properties
Fertilizer Soluble Ammonium Polyphosphate SAP is stable and not easy to volatilize. Its density is slightly greater than that of water. It can gradually dissolve in water. The aqueous solution is weakly alkaline and can react with strong acid.
Technical Specifications & Labeling
The specifications of Fertilizer Soluble Ammonium Polyphosphate SAP are mostly based on phosphorus and nitrogen content. The label must clearly state the product name, ingredients, content, production date, shelf life and storage points.
Preparation Method
Fertilizer Soluble Ammonium Polyphosphate SAP is usually made of phosphoric acid and ammonia as raw materials, and is made through heating, polymerization and other processes. The process requires temperature and pressure control to obtain the desired product.
Chemical Reactions & Modifications
Fertilizer Soluble Ammonium Polyphosphate SAP can be gradually decomposed into phosphate and ammonium in the soil, which are absorbed by crops. If it encounters a strong reducing agent, it may undergo redox changes, but violent reactions are rare in daily use.
Synonyms & Product Names
Fertilizer Soluble Ammonium Polyphosphate SAP also has aliases, but its correct name is correct, and the industry mostly calls it this, and few other names are circulated.
Safety & Operational Standards
Those who handle Fertilizer Soluble Ammonium Polyphosphate SAP should wear gloves and masks to avoid it from entering the eyes and mouth. If it is accidentally contaminated, it should be rinsed with clean water immediately; it should also be spread evenly when applied to avoid excessive concentration and damage to seedlings.
Application Area
Fertilizer Soluble Ammonium Polyphosphate SAP is mostly used in farmland, orchards, and vegetable gardens. It can be used to fertilize crops such as wheat, corn, fruits and vegetables. It can be used as base fertilizer or topdressing fertilizer. It can be dissolved in water and sprayed or drip-irrigated.
Research & Development
Today's researchers are still exploring the better preparation process of Fertilizer Soluble Ammonium Polyphosphate SAP to reduce costs and increase efficiency. At the same time, they are studying its application methods on different soils and different crops, hoping that its effectiveness will be more significant.
Toxicity Research
After investigation, Fertilizer Soluble Ammonium Polyphosphate SAP has very low toxicity. However, if it is accidentally ingested in large quantities, it may damage the stomach and intestines. Therefore, it needs to be stored properly and kept out of reach of children and livestock.
Future Prospects
In the future, the demand for Fertilizer Soluble Ammonium Polyphosphate SAP may increase day by day, because modern agriculture seeks high yield and high efficiency, and its easy solubility and high nutrient content will be more popular, and the process will also be more refined and more environmentally friendly.

What are the special requirements for the preparation of Fertilizer Soluble Ammonium Polyphosphate SAP?
The preparation of this product requires hot phosphoric acid and food-grade ammonia as raw materials. Because it is used for crops, the purity of the raw materials is particularly important. Put the phosphoric acid in an enamel reactor and heat it to 170 degrees. When ammonia is introduced, it must be purified to remove impurities. Stir with a silver spoon while passing it. When the pH value reaches 6.2, raise the temperature to 210 degrees to polymerize, and continue for four hours. Samples are taken every hour to ensure that the heavy metal content does not exceed the standard. After cooling, it can be quickly dissolved in water without residue, and Fertilizer Soluble Ammonium Polyphosphate SAP is obtained. The method is similar to brewing rice wine, which requires clean utensils and clean materials. The slightest contamination will damage its properties, so it needs to be carefully crafted.
What is unique about Fertilizer Soluble Ammonium Polyphosphate SAP for crops?
When this product is applied to crops, its phosphorus element exists in a polymerized state. After being absorbed, it is slowly released. The fertilizer effect can last for more than two months, and it is more resistant to rain erosion than ordinary phosphorus fertilizers. When used on root vegetables such as radishes and potatoes, it can promote the expansion of tubers and reduce deformities; when applied to leafy vegetables, it can make the leaves thicker and darker green. In alkaline soil, it can chelate calcium ions to prevent phosphorus from being fixed, and increase the utilization rate by more than 80%. When sprayed on the leaves of fruit trees, it can be directly absorbed through the epidermis and take effect within three days, making the new shoots grow strong. Its use is like a good doctor giving medicine, which takes effect accurately without wasting a single cent.
What should be paid attention to when Fertilizer Soluble Ammonium Polyphosphate SAP is mixed with similar fertilizers?
This product can be mixed with urea and potash fertilizers to enhance and complement each other, but it cannot be stored with ammonium sulfate, otherwise it will easily absorb moisture and form lumps. When mixed with superphosphate, it must be prepared and used immediately, otherwise it will reduce the phosphorus effect if left for a long time. If mixed with farmyard manure, the farmyard manure must be decomposed first to avoid unripe materials consuming its nutrients. Mixing with gypsum in saline-alkali land can enhance the effect of improving soil, but the ratio must be controlled at three to one, otherwise it will damage the soil fertility. Although it is mild in nature, it is still necessary to test it on a small scale before mixing it with other crops to see if there are any adverse reactions before applying it on a large scale.
What are the differences in the dosage of Fertilizer Soluble Ammonium Polyphosphate SAP for different crops?
For wheat, 20 kilograms per mu are used, and topdressing is performed during the tillering period to promote effective tillering; 25 kilograms are required for corn, and hole application is performed during the jointing period to help the stems grow thicker. For fruit trees such as apples, 8 kilograms are applied per plant, half before and after the flowering period, which can promote fruit setting; 5 kilograms per grape plant are applied in furrows during the fruit swelling period to increase the sweetness of the fruit. For vegetables, 30 kilograms per mu of tomatoes are applied in three drops to prevent navel rot; 20 kilograms per mu of cucumbers are applied with water flushing to promote straight growth of melon strips. The dosage should be based on the characteristics of the crop's fertilizer needs. Too much will cause excessive growth, too little will cause insufficiency, and only the right amount will produce good results.
How to judge the quality of Fertilizer Soluble Ammonium Polyphosphate SAP?
The high-quality ones have uniform particles, no broken pieces, and uniform color. They will dissolve completely within five minutes after being soaked in water, and the aqueous solution will be clear. Take a small amount and burn it. The pure product will decompose completely without black smoke residue; if there is a burnt smell, it contains impurities. Measure the pH value of its aqueous solution, which should be 7.3 to 7.6. Too acidic or too alkaline are not good products. Take a sample and mix it with an equal amount of lime. The high-quality ones only release a slight ammonia smell. If the smell is strong, the purity is insufficient. Its packaging must be marked with "fertilizer grade" and nutrient content. Be careful if there is no mark or the handwriting is blurred, as it may be an industrial grade imitation.
