Trident®

Trident® is a nitrogen stabilization and nitrogen-management technology from Verdesian Life Sciences. It is designed for integration with nitrogen fertiliser programs to help protect applied nitrogen against important loss pathways and support nitrogen use efficiency.

A nitrogen stabilizer is used with nitrogen fertiliser to influence specific chemical or biological processes that can expose applied nitrogen to loss.

Different stabilization technologies address different mechanisms. Product selection should therefore be matched to the nitrogen source, application method and field-loss risks.

Verdesian positions the Trident® platform around three important nitrogen-loss pathways:

• Volatilization — potential ammonia loss to the atmosphere.
• Nitrification — microbial transformation of ammonium toward nitrate.
• Denitrification — microbial conversion of nitrate into gaseous nitrogen forms under suitable soil conditions.

When urea-containing fertiliser is applied to the surface, nitrogen can under certain conditions be lost as ammonia gas before adequate incorporation occurs.

Temperature, moisture, soil conditions, crop residue and the timing of rainfall or irrigation can influence this risk.

Nitrification is the biological conversion of ammonium nitrogen toward nitrate nitrogen. Nitrate is readily available to crops but is also more mobile in soil than ammonium and can be vulnerable to other loss pathways when environmental conditions are favourable.

Denitrification is a microbial process in which nitrate is converted into gaseous nitrogen forms. It becomes particularly relevant under conditions of reduced soil oxygen, often associated with wet or saturated soils.

Published Verdesian information describes the Trident® platform as incorporating established nitrogen-management active ingredients including NBPT and DCD together with proprietary co-polymer and solvent technology.

Exact formulation and active ingredient concentrations depend on the specific Trident® product and registration. Always consult the current local label.

NBPT is used in urease-inhibitor technologies intended to manage the enzymatic process involved in urea conversion following application. This approach is associated with management of ammonia volatilization risk from urea-containing nitrogen fertilisers.

DCD is used in nitrification-management technologies to influence the microbial transformation of ammonium nitrogen toward nitrate.

The agronomic objective is to manage nitrogen transformation where maintaining more nitrogen in the ammonium pool for a period may reduce exposure to nitrate-related loss pathways.

Published Verdesian information describes Trident® formulations for use with urea. The exact formulation, treatment rate, mixing procedure and permitted use must be confirmed from the current label applicable in your market.

Published Verdesian product information includes Trident® formulations for UAN nitrogen fertiliser. Product selection, rate, mixing and application instructions can differ by market and formulation.

No such assumption should be made. Nitrogen fertilisers differ chemically, and Trident® formulations have specific approved uses.

Confirm that the exact nitrogen fertiliser source appears within the current approved product directions before treatment or mixing.

Atlas Crop Technologies lists Broadcast and Fertigation among the application routes for Trident®. The exact method depends on the formulation, nitrogen source and local registration.

There is no single universal Trident® rate that should be applied across all formulations and countries. Rates depend on the exact product, nitrogen fertiliser, application system and local registration.

Use only the application rate stated on the current approved label for the Trident® product supplied in your market.

Trident® is a nitrogen-management technology, not a substitute for determining an agronomically appropriate nitrogen rate.

Nitrogen rate decisions should be based on crop demand, soil nitrogen, expected yield, previous crop, organic nutrient sources, local recommendations and regulatory requirements.

Trident® is positioned as a nitrogen stabilizer used alongside nitrogen fertiliser. It is intended to help manage nitrogen-loss processes rather than replace the crop's nitrogen fertiliser requirement.

Risk depends on the nitrogen form and field conditions. Examples include surface-applied urea before incorporation, nitrogen exposed to warm and biologically active soils for extended periods, and nitrate present during excessive rainfall or saturated soil conditions.

Yes. Temperature influences microbial activity and the rate of many nitrogen transformation processes. Moisture, oxygen status and other soil conditions interact with temperature, so risk should be evaluated as part of the complete field environment.

Yes. Appropriate rainfall can help incorporate some surface-applied nitrogen, while excessive rainfall can increase nitrate movement or create saturated soil conditions associated with denitrification risk.

Poorly drained soils can experience periods of saturation associated with higher denitrification risk. Whether a particular Trident® use is appropriate depends on nitrogen source, timing, crop, field conditions and the approved local label.

Compatibility must be confirmed for the specific products and mixture. Fertiliser chemistry, concentration, water quality, temperature and mixing order can influence compatibility.

Follow all relevant product labels and obtain qualified technical advice for mixtures not specifically covered by product documentation.

Product registration and use directions vary by country. Suitability also depends on the crop's nitrogen program and the fertiliser source being treated.

Confirm the local registration and agronomic fit before use.

No. Registration, formulation, product claims, active ingredient concentration, fertiliser compatibility, pack size and directions can vary substantially between countries.
