Ammonium sulfate is an inorganic substance, chemical formula (NH4)2SO4, colorless crystals or white particles, odorless. Decomposition above 280℃. Solubility in water: 70.6g at 0℃, 103.8g at 100℃. Insoluble in ethanol and acetone. A 0.1mol/L aqueous solution has a pH of 5.5. The relative density is 1.77. Refractive index 1.521. Ammonium sulfate is mainly used as a fertilizer and is suitable for a variety of soils and crops. It can also be used in textile, leather, medicine and so on.
Calcium ammonium nitrate is a compound fertilizer, white round granulated, easily soluble in water, with strong hygroscopic, caking, flammable and explosive, is a new type of efficient compound fertilizer containing nitrogen and fast-available calcium, its fertilizer efficiency is fast, with the characteristics of rapid nitrogen supplement, in which the addition of calcium, the nutrient is more comprehensive than ammonium nitrate, plants can directly absorb; This product is a neutral fertilizer, the physiological acidity is small, and it has an improving effect on acidic soil. After applying to the soil, the pH is small, will not cause soil compaction, and can make the soil loose. At the same time, it can reduce the concentration of active aluminum, reduce the fixation of active phosphorus, and provide water-soluble calcium, which can improve the resistance of plants to diseases. It can promote the activity of beneficial microorganisms in the soil. When planting cash crops, flowers, fruits, vegetables and other crops, the fertilizer can extend the flowering period, promote the normal growth of roots, stems and leaves, ensure the bright color of the fruit and increase the hardness of the fruit.
