TSP is commonly use as phosphate fertilizer, which has the following main uses in agriculture:
1.Phosphate fertilizer supplement: TSP is a kind of phosphate fertilizer, which contains high concentration of phosphorus element. Phosphorus is one of the main nutrients necessary for plant growth and development, and plays an important role in promoting plant root growth, flower and fruit coloring, and enhancing stress resistance. Heavy superphosphate can effectively supplement the lack of phosphorus in the soil, and improve the growth rate, yield and quality of plants.

2.Soil conditioning: Heavy superphosphate can improve soil structure and nutrient supply capacity. Phosphorus is beneficial to promote the decomposition of organic matter and the release of minerals in the soil, and increase the fertility and water retention capacity of the soil. At the same time, heavy superphosphate can neutralize the acidity of the soil, improve the pH value of the acidic soil, and provide a suitable growth environment.
3.Seed treatment: For seed treatment. Soaking the seeds in the double superphosphate solution can provide the seeds with essential phosphorus and other nutrients, promote the germination and growth of the seeds, and increase the germination rate and survival rate of the seeds.

NOTE: When using double superphosphate, it should be applied in the correct proportion and method, and follow the relevant norms and guidance of agricultural production. At the same time, according to the actual situation of soil and crops, scientific fertilization and reasonable conditioning should be carried out to maximize the effect of superphosphate.
