Calcium ammonium nitrate is a new high-efficiency compound fertilizer containing nitrogen and available calcium

Calcium ammonium nitrate is a compound fertilizer. It is a new high-efficiency compound fertilizer containing nitrogen and available calcium. It has the characteristics of fast fertilizer effect and rapid nitrogen supplement. Calcium is added, the nutrients are more comprehensive than ammonium nitrate, and can be directly absorbed by plants; Calcium  ammonium nitrate is a neutral fertilizer with low physiological acidity and can improve acidic soil. After being applied into the soil, the pH is small, which will not cause soil hardening 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 soil. When planting cash crops, flowers, fruits, vegetables and other crops, the fertilizer can prolong the flowering period, promote the normal growth of roots, stems and leaves, ensure bright fruit color and increase fruit sugar. Calcium ammonium nitrate  is suitable for a variety of soils and crops. It is widely used in food crops, cash crops, flowers, fruit trees, vegetables and so on. The nitrate nitrogen in calcium ammonium nitrate does not need to be transformed in soil first, but dissolves rapidly in water and is directly absorbed by plants. It is suitable for base fertilizer, seed fertilizer and topdressing. Calcium ammonium nitrate contains a large amount of calcium carbonate, which has a good effect and effect as topdressing in acidic soil. When applied in paddy field, the fertilizer effect was slightly lower than that of ammonium sulfate with the same amount of nitrogen, while when applied in dry land, the fertilizer effect was similar to that of ammonium sulfate. The cost of nitrogen in calcium  ammonium nitrate is higher than that in ordinary ammonium nitrate. As a low concentration fertilizer, calcium ammonium nitrate is a physiological neutral fertilizer. Long-term application plays a good role in soil properties. It can be used as topdressing for cereal crops. Calcium ammonium nitrate  for agriculture can also reduce the concentration of active aluminum and the fixation of active phosphorus. The water-soluble calcium provided can improve the resistance of plants. When planting cash crops, vegetables, fruits, flowers and other crops, it can prolong the flowering period, promote the normal growth of roots, stems and leaves, ensure the bright color of fruits and increase the sugar content of fruits. Through root transpiration, plants transport nitrate nitrogen and calcium ions to rhizomes, flowers, leaves and fruits for direct absorption. This is the principle that calcium ammonium  nitrate can rapidly supplement nitrogen and calcium. According to the experience of farmers, the effect can be achieved 3 hours after calcium ammonium nitrate fertilization, and the effect is obvious 3 days later. Because of its water-soluble characteristics, foliar spraying is also a good choice. It can be diluted 800-1000 times and used with other pesticides or foliar fertilizer. As a neutral fertilizer, calcium ammonium nitrate is suitable for a variety of soils and crops. The nitrate nitrogen in calcium ammonium nitrate does not need to be transformed in the soil first, but quickly dissolves in the water and is directly absorbed by plants. It has the effect of improving the acidic soil without causing soil hardening and loosening the soil. From the first step of soil use, we have achieved protection and improvement, and fundamentally put an end to the problem of soil pollution.
