However, fused phosphorus fertilizer is a free fertilizer made by melting phosphorescent material and serpentine at high temperature, quenching it with cold water, drying, and pulverizing it, and since it does not have any binding substances, it is commercialized in powder form. Therefore, it cannot be granulated without adding a caking substance.

Table 1. Particle size distribution of dissolved phosphorous fertilizer As mentioned above, dissolved phosphorous fertilizer is a phosphorus II' fertilizer or an alkaline fertilizer containing lime, magnesia, silicic acid, etc. as subcomponents, so granulation of dissolved phosphorous fertilizer is difficult. The properties of dissolved phosphorus fertilizers must be maintained. Among the methods for granulating melted phosphorous fertilizer, a method of mixing superphosphate lime with strong caking power and melted phosphorous fertilizer and granulating it was published in the Japanese Patent Application Publication in 1987.
8525 and 87-10582. The viscous dissolved phosphorus obtained by this method is good in terms of particle size, longitude, and physical properties, but it has the drawback of acidifying alkaline fertilizers due to the addition of sulfuric acid.

At 2.8 kFl/particle, it is hard and hard, but it is dispersed in water, so it is excellent as a granular product. In this case, the mixing ratio of dissolved phosphorus fertilizer and phosphoric acid lime, and the mixing ratio of amino #koji soup stock liquid and phosphoric acid. can be adjusted according to the phosphoric acid content of the product. In this case, a total amount of starch less than or equal to aSS may be added to the mixture. Also.

Although granulation is possible without adding phosphoric acid to the amino WR fermentation waste liquid, the mildness is lowered and the physical properties are inferior, so the liquid is used in the amino acid fermentation sub-# to adjust the pH to 8 to obtain a product with high strength. However, phosphoric acid must be added because it has the advantage of controlling the phosphoric acid content of the final product.

また、燐識石灰を製造して溶成燐肥と混合造粒する理由
は、溶成燐肥に燐酸を直接加えれば溶成燐肥の燐酸含量

Furthermore, the reason why phosphorous lime is produced and mixed and granulated with melted phosphorous fertilizer is that if phosphoric acid is directly added to the melted phosphorous fertilizer, the phosphoric acid content of the melted phosphorous fertilizer will increase, and its dispersibility in water will decrease.

Therefore, first, phosphoric acid is reacted with slaked lime or lime carbonate, which has a light specific gravity, to produce phosphoric acid lime, and then added to the molten phosphorus fertilizer.Since the molten phosphorus fertilizer is O#, the content of lime and magnesia can be reduced over time. This fertilizer maintains the alkalinity, which is the original characteristic of dissolved phosphorus fertilizer, so that crops can be easily harvested in the soil.
