The calcium cyanamide product is an agricultural fertilizer, usually composed of a mixture of lime and nitrogen elements. They have some advantages in agriculture, here are some of them:

1. Provide nitrogen and calcium: Calcium cyanamide products not only provide nitrogen for plants, but also provide calcium, which is essential for plant growth and development. Calcium is an important component in building plant cell walls and can enhance the structural stability of plants.

2. Acidic soil improvement: The lime in calcium cyanamide products can help neutralize acidic soil and make it more suitable for plant growth. Soil that is too acidic may limit the absorption of nutrients by plants, and the addition of lime can improve the acid-base balance of the soil.

3. Long-acting nitrogen sources: Calcium cyanamide products usually have long-acting nitrogen release properties, which means that they can provide the required nitrogen for a longer period of time. This helps to reduce the frequency of multiple topdressing, reducing labor costs and resource waste.

4. Avoid nitrogen loss: Compared with some other nitrogen fertilizers, calcium cyanamide products can reduce the risk of nitrogen loss to a certain extent, such as the loss of volatile ammonia. This helps to improve nutrient efficiency and reduce the negative impact on the environment.

5. Reduce nutrient loss: Since calcium cyanamide products contain calcium, they can help reduce the loss of other nutrients in the soil, such as phosphorus. This helps maintain the nutrient balance of the soil.

It is important to note that the specific benefits of calcium cyanamide products may vary depending on product formulation, soil type, and crop needs. Before using any fertilizer, it is best to conduct soil testing and crop needs analysis to determine the type and amount of fertilizer that is best for your specific agricultural environment. In addition, proper fertilizer management is also very important to maximize the advantages and minimize the negative effects.
