New field trials confirm Green Urea NV® reduced nitrogen losses by up to 82%

New multi-site agronomy partner field trials conducted across South Australia and Victoria have demonstrated the significant role enhanced efficiency fertilisers can play in protecting nitrogen (N) following winter topdressing.

The latest field trials have proven that standard surface-applied urea can lose up to 22% of applied nitrogen through ammonia volatilisation within two weeks of application. In comparison, Green Urea NV® reduced nitrogen losses by an average of 79%, with reductions of up to 82%.

Conducted across key southern cropping regions, the trials reinforce the importance of protecting nitrogen investments during winter, when surface applications are common and seasonal conditions can increase the risk of volatilisation losses.

Key findings from the 2025 trials include:

• Standard surface-applied urea lost up to 22% of applied nitrogen through ammonia volatilisation within two weeks.
• Green Urea NV® reduced nitrogen losses by an average of 79%, with reductions of up to 82%.
• Improved nitrogen retention within the production system.
• Greater flexibility around top-dress application timing while supporting improved nitrogen use efficiency.

The results build on similar multi-site trials completed in 2024, providing growers with continued confidence in Green Urea NV®'s ability to help protect nitrogen across a range of seasonal conditions.

As winter topdressing continues across many cropping regions, the findings provide timely insights for growers seeking to maximise fertiliser efficiency and retain more nitrogen where crops need it most.
