Product Description Product DescriptionCalcium superphosphate is also known as universal calcium, ordinary calcium superphosphate, superphosphate lime, superlime .The main components are calcium dihydrogen phosphate (Ca (H2PO4)2) and calcium sulfate (CaSO4), the effective content of phosphorus is generally 14%-20%, the different content corresponds to the different prices.Its appearance is off-white, dark gray to gray-brown powder or granule.Solubility: Most of it can be dissolved in water, the aqueous solution is slightly acidic, a small part of it is insoluble in water and easily soluble in 2% citric acid (citrate) solution.It provides nutrients: It can provide plants with phosphorus, calcium, sulfur and other elements, of which phosphorus plays an important role in the growth process of plants, such as germination, root growth, branching, fruiting and maturity.It improves soil: it is suitable for neutral, slightly alkaline and alkaline soil, rich in gypsum and free acid can improve alkaline soil.ItemParameterTotal P2O5 ≥21%Effective P2O5 ≥18Souble P2O5≥14Calcium as CaO18-20%Free Acid≤5.5%Product advantagesTake effect quickly and meet the needs of the critical periodSuperphosphate is a quick - acting phosphate fertilizer. After being applied to the soil, the water - soluble monocalcium phosphate in it can dissolve rapidly, releasing phosphate ions, which are quickly absorbed by the roots of crops. During the critical growth periods of crops, such as the root development stage at the seedling stage, and the flower bud differentiation and fruit - setting stages at the flowering stage, timely supplementation of phosphorus can significantly promote the growth and development of crops, improve their stress resistance, and lay a solid foundation for high and stable yields of crops.Improve the soil and create a good environmentAs an acidic fertilizer, when superphosphate is used in acidic soil, on the one hand, it can react with the alkaline substances in the soil to neutralize them, reducing the soil's pH value and alleviating the degree of soil acidification. On the other hand, the calcium ions it contains can promote the formation of soil aggregate structure, improve the physical properties of the soil, increase the soil's air permeability and water and fertilizer retention capacity, and create a more suitable growth environment for crop roots.Persistent after - effect, long - term supply of nutrientsIn addition to its quick - acting characteristic, superphosphate also has a certain residual effect. The phosphorus elements that are not completely absorbed by crops in the current season will accumulate in the soil and be converted into citrate - soluble phosphorus. During the subsequent growth process of crops, with the changes in the soil environment, such as the activities of microorganisms and the organic acids secreted by roots, the phosphorus will be gradually released, continuously providing phosphorus nutrition for crops, and reducing the frequency and amount of fertilizer application.Scope of application1.A powerful tool for increasing the yield of field cropsWhen used as a base fertilizer in the cultivation of food crops such as wheat and rice, superphosphate can promote the growth and tillering of crop roots, and increase the number of effective panicles and the seed - setting rate of crops. A large number of practices have shown that after rational application, the mu yield of wheat can be increased by 10% - 15%, and the mu yield of rice can be increased by 12% - 18%.2.Quality guarantee for cash cropsFor cash crops such as cotton and rapeseed, superphosphate has a significant effect on promoting flower bud differentiation, increasing the fruit - setting rate and fruit quality. Taking cotton as an example, it can increase the number of cotton bolls, improve the fiber length and strength of cotton, and enhance the commercial value of cotton. In rapeseed cultivation, it can increase the oil content of rapeseeds by 2 - 3 percentage points.3. A capable assistant for fruit and vegetable cultivationIn the cultivation of fruit trees and vegetables, superphosphate can not only promote the flower bud differentiation of fruit trees, improve the quality and yield of fruits, but also enhance the disease and pest resistance of fruit trees. In vegetable cultivation, it can make vegetables grow more robustly, with bright colors and better taste. At the same time, it can reduce the occurrence of physiological diseases, such as blossom - end rot of tomatoes.
