Dicyandiamide (DCD) - Inhibitor of nitrification in agriculture, Kyiv region.

Dicyandiamide (DCD) is a highly effective nitrification inhibitor whose unique chemical structure allows it to target the key microorganisms responsible for the process nitrification in the soil. According to the data of the analysis certificate, the Chinese DCD has a purity of 99.6% (with a minimum permissible of 99.5%), which guarantees maximum biological activity and predictability of action in field conditions.

Nitrification is a two-stage biochemical process in which ammonium (NH₄⁺) contained in the soil is first converted into nitrite (NO₂⁻) and then into nitrate (NO₃⁻) under the action of specific soil bacteria. Dicyandiamide specifically inhibits the first stage of this process, blocking the activity of bacteria of the genus Nitrosomonas, which oxidize ammonium to nitrite. The high purity of the product (99.6%) and the low content of impurities (ash 0.03%, calcium 122 μg/g) ensure a stable and predictable effect of DCD without side effects associated with pollutants.

Advantages of using dicyandiamide in agriculture
1. Reduction of nitrogen losses
Without the use of inhibitors, up to 50-70% of the applied nitrogen can be lost as a result:

Nitrate leaching is a process in which soluble nitrates are carried by water into the deep layers of the soil, becoming inaccessible to plants and contaminating groundwater.
Denitrification is the transformation of nitrates into gaseous forms (N₂O, N₂) that evaporate into the atmosphere.
Ammonia volatilization is the evaporation of ammonia from the soil
High-quality dicyandiamide (with a purity of 99.6%, as in the sample from ENION INDUSTRIAL) allows you to reduce these losses by 30-50%, keeping nitrogen in the ammonium form, which is better retained by the soil and becomes available to plants more slowly.

2. Increasing the efficiency of nitrogen use by plants
Traditionalnitrogen fertilizers have plant utilization coefficient of only 30-50%. When adding DCD, this indicator increases to 60-80%, which means:

More uniform nutrition of plants throughout the growing season.
Reduction of the risk of plant burns by high concentrations of nitrates
Improvement of assimilation of other nutrients due to balanced nutrition.
Increasing the resistance of plants to stress factors (drought, diseases)(//tractor-service.com)
It is especially important that the high purity of Chinese DCD (99.6%) and the low content of melamine (266 ppm at the limit of 500 ppm) guarantee the absence of toxic effects on plants even when used in recommended doses.

3. Economic benefits for farmers
The use of dicyandiamide as a nitrification inhibitor provides farmers with significant economic benefits:

Reduction of the need for nitrogen fertilizers by 20-30% without loss of productivity
Reducing the amount of applied fertilizer that reduces labor and fuel costs.
The possibility of applying fertilizers "in one application" instead of several top dressings.
Increase in productivity by 5-15% depending on the culture and growing conditions.

Dosing and application methods
The optimal dose of dicyandiamide as a nitrification inhibitor is 0.5-2.0% of the mass of nitrogen fertilizer. The specific dose depends on:

Type of soil (a slightly larger dose is required on sandy soils)
Climate conditions (temperature and amount of precipitation)
The type of crop and its nitrogen requirements
Fertilizer application method.

Conclusion on application
Dicyandiamide as a nitrification inhibitor is a technological solution that allows overcoming one of the main challenges of modern agriculture — ineffective use of nitrogen fertilizers. A high-quality product from Chinese manufacturers that meets strict standards (purity 99.6%, melting point 211°C, low content of impurities), provides farmers with the opportunity to significantly increase productivity while simultaneously reducing the negative impact on the environment.
