The value of protecting nitrogen
More nitrogen retained. More return per hectare.
Preserva improves nitrogen efficiency by ~9% in typical conditions, reducing volatilisation losses and increasing the amount of nitrogen available to the plant.
This additional nitrogen can translate to ~100–200 kg of extra dry matter per hectare, depending on conditions and utilisation.
As fertiliser prices increase, the value of retained nitrogen increases directly — improving the return on every tonne applied.
-
Typically delivers 2–3x return on treatment cost
-
Converts more applied nitrogen into plant growth
-
Reduces waste from volatilisation losses
~9%
~9% more plant-available nitrogen in typical conditions —
a direct measure of field performance.
100-200kg
Additional dry matter per hectare
2-3x
Return on treatment cost
*Dependent on conditions and utilisation
Not all nitrogen protection is equal —
what matters is how much remains available to the crop

Performance that holds through blending
Designed for real-world fertiliser systems — not just straight urea.
• Maintains NBPT performance in acidic and phosphate blends
• Stable through blending, storage and transport
• Compatible with standard blending infrastructure
• Solvent-Free for consistent worker safety
• Consistent performance across field conditions
Where solvent-based systems fall short
Solvent-based systems
• Performance loss in blends
• Sensitivity to acidic components
• Handling and compatibility constraints
Preserva solvent-free system
• Stable NBPT performance in blends
• Solvent-Free for consistent worker safety
• Designed for blending, not just coating
Built for how fertiliser is actually used – not just how it’s tested.

Nitrogen loss from untreated urea can average ~18% without timely rainfall.
Preserva reduces early-stage losses – retaining more nitrogen in the soil, where it drives growth
Indicative comparison based on 50 kg N/ha application and typical nitrogen loss assumptions
BUILT ON PROVEN UREASE INHIBITOR CHEMISTRY
ENGINEERED FOR REAL-WORLD FERTILISER SYSTEMS
How Preserva Improves Nitrogen Efficiency
- Uses NBPT urease inhibitor technology to slow urea hydrolysis
- Engineered formulation helps stabilisation and maintaining inhibitor performance in challenging blend conditions
- Maintains active performance through storage and transport
- Reduces ammonia volatilisation during the critical early application period
Performance over time
- Reduces early-stage nitrogen loss from urea (first 48 hours)
- Maintains inhibitor performance through blending, storage, and handling
- Delivers consistent efficacy post-blend
- Retains effectiveness even after extended storage periods
Immediate Nitrogen Loss Reduction
50% LOWER
AMMONIA LOSS VS UNTREATED UREA
Performance After Blending & Storage (90 Days)
Performance maintained across common fertiliser blends, even after extended storage.

Preserva is available in multiple colours
Being solvent-free, Preserva uses pigment instead of dyes – resulting in longer-laster, more vibrant colouring on urea
