Calcium nitrate is best applied to crops such as sugar beet, potato, barley, hemp, etc., and it is widely applied to all kinds of soils, especially on calcium-deficient acid soils, and its effect will be better. Calcium nitrate has the characteristics of rapid calcium supplementation and nitrogen supplementation. Its unique combination of nitrate nitrogen and 100% water-soluble calcium provides the properties and advantages that many other fertilizers do not have. It is one of the most valuable fertilizers on the market. Each calcium nitrate contained 11.8% of nitrogen (nitrate) and 23.7% of water-soluble calcium uniformly, which was beneficial to the absorption of nutrients by crops, enhanced the resistance of fruits and vegetables, promoted early maturing, and improved the quality of fruits and vegetables in agriculture. It is widely used in base application, topdressing, flushing and foliar spraying, and can also be used as soilless culture solution. It is rich in calcium ions, and its application year after year will not only deteriorate the physical properties of the soil, but also improve the soil. The advantages of calcium nitrate Good safety performance, easy storage and handling. Ammoniated calcium nitrate and calcium nitrate for agriculture are alternatives to ammonium nitrate, a safer nitrate nitrate than ammonium nitrate. Due to the presence of calcium, agricultural calcium nitrate is less hygroscopic than ordinary ammonium nitrate, thus improving the caking property and thermal stability. It is not prone to fire and explosion during storage and handling. Nitrate-nitrogen is predominant, and calcium is added, making crops indispensable. Agricultural calcium nitrate is a new high-efficiency chemical fertilizer containing nitrogen and available calcium. The calcium nitrate used in agriculture contains a large amount of nitrate nitrogen, which can be directly absorbed and utilized by plants without conversion from ammonium nitrogen and amide nitrogen. Calcium is one of the essential nutrients for the growth and development of crops and plays an important role in the growth of crops. According to the analysis of relevant experts, the demand for calcium in many crops is only inferior to nitrogen and potassium, but higher than phosphorus. Low volatility loss and high utilization. According to domestic and foreign data shows: urea and ammonium bicarbonate in the storage and use of nitrogen loss in the 40% to 50%. The annual environmental pollution caused by the loss of nitrogen in China is also very serious. Therefore, improving fertilizer utilization and protecting the environment have become one of the most important problems in the development of agriculture in China. The nitrate nitrogen contained in agricultural calcium nitrate can be directly absorbed by crops without the need of soil conversion, and the loss of nitrogen is small. As a base fertilizer and top dressing, the nitrate fertilizer can quickly make up the nitrogen. Calcium nitrate usage Suitable for topdressing in dry fields. However, it should be noted that calcium nitrate fertilizer nutrients are more likely to be lost and must be applied in small portions, and generally do not apply before rain. When used as a basal fertilizer, it can be combined with decomposed organic fertilizers, phosphate fertilizers (calcium superphosphate) and potash fertilizers, which can significantly improve fertilizer efficiency. However, it should not be mixed with superphosphate alone to prevent the decrease of phosphate fertilizer efficiency. Because of the lower nitrogen content of calcium nitrate, the amount used is more than that of other nitrogen fertilizers.
