Detailed information on dicyandiamide in agricultural fertilizers

Dicyandiamide is mainly used in the production of long-acting nitrogen fertilizers in the field of agricultural fertilizers.

Dicyandiamide can inhibit the activity of nitrifying bacteria in the soil, thereby slowing down the conversion of ammonium nitrogen to nitrate nitrogen. This process is crucial because nitrate nitrogen is prone to being lost with water or through denitrification, while ammonium nitrogen is relatively stable and more conducive to plant absorption.

In specific applications, dicyandiamide is often used together with nitrogen fertilizers such as urea. After the fertilizer containing dicyandiamide is applied to the soil, dicyandiamide will gradually decompose in the soil, and its inhibitory effect has a certain time range. In this way, during the critical period of crop growth, sufficient ammonium nitrogen supply in the soil can be ensured, reducing the leaching and volatilization losses of nitrogen, and then improving the utilization rate of nitrogen fertilizers, which can generally be increased by about 10% - 20%.

From an environmental protection perspective, the use of dicyandiamide helps to reduce the risk of water pollution caused by the loss of nitrogen fertilizers. For example, in some areas with a high degree of agricultural intensification and close to water bodies, the use of fertilizers containing dicyandiamide can effectively reduce the amount of nitrogen entering the water bodies, which has a positive impact on protecting the ecological environment of water areas.
