Key Performance Characteristics
Predictability: Because the ISODUR® nitrogen is released by hydrolysis (water breaking down the molecule), the release rate mirrors the transpiration rate of the grass. When the grass needs water and heat to grow, the fertiliser releases more nitrogen.
Root Development: Unlike fast-acting urea which promotes "top-heavy" leaf growth, N 31 encourages a balanced root-to-shoot ratio, essential for sports pitches that take heavy wear.
Cold Start: It is the "First Out of the Bag" product for many greenkeepers because it doesn't have to wait for soil microbes to wake up in the spring.
Usage Recommendations
Usage Recommendations
Fine Turf (Golf Greens/Tees): Use at the lower 20g/m2 rate for frequent, light feeding.
Sports Turf (Football/Rugby): Use at 30g–40g/m2 for deep color and high wear tolerance during the playing season.
Application Note: For best results, apply to dry turf and irrigate with 3–5mm of water immediately after application to move the granules into the sward.
N31 with ISODUR®. The Gold Standard of Nitrogen.
N31 with ISODUR®. The Gold Standard of Nitrogen.
Total control. Zero compromise. N31 isn't just a fertiliser; it’s a high-performance nutrition system that synchronises perfectly with your turf's biological clock.
Weather-Independent
Unlike standard urea, ISODUR® doesn't care if it’s cold or if the soil biology is dormant. It releases based on moisture, ensuring your plants are fed from the first frost to the summer heat.
The Power of 31
One of the highest concentrations of slow-release nitrogen available. You apply less weight, cover more ground, and achieve superior results.
Zero Burn, All Growth
With an incredibly low salt index, N31 is gentle on roots and young shoots, making it the safest choice for high-value turf.
Synced with the Soil. Powered by ISODUR®.

N31. Synced with the Soil.
Modern turf management isn't just about results; it's about accountability. Traditional nitrogen risks leaching and atmospheric waste. N31 with ISODUR® stops the loss. By releasing nitrogen through moisture alone (hydrolysis), it stays locked in the root zone—synchronised with your turf's needs, reducing input waste and protecting the environment. N31 delivers a flawless, deep-green aesthetic without the volatile growth surges that compromise shear strength and ball roll.
Engineering the Perfect Growth Curve
Most fertilisers offer a "spike and crash"—a rush of growth followed by a hungry plant. ISODUR® changes the physics of feeding. Through a process called hydrolysis, N31 releases nitrogen steadily over 3 to 4 months.

Powered by ISODUR®. Engineered for Stadium Strength.
In professional football and rugby, aesthetics are only half the battle. Your surface must be dense, resilient, and ready to stand up to intense wear, all while looking flawless under the stadium lights. N31 with ISODUR® delivers a steady, unwavering supply of nitrogen that builds strong plants, not just lush tops.
Strength from the Ground Up.
Strength from the Ground Up.
Standard nitrogen creates a "lush push"—soft, top-growth that is easily damaged by studs and weakens the plant. N31 changes the curve.
Controlled Stamina: ISODUR® provides a flat nitrogen release over 3 to 4 months. You get consistent, professional colour without the volatile growth surges.
Shear Strength Focused: Steady, moderate nutrition promotes a deep, tenacious root system. Stronger roots mean better shear resistance for stable footing and less tearing during match play.
Rapid, Resilient Recovery: Unlike immediate-release N, N31 provides the energy for constant tillering and repair, ensuring pitch recovery without the soft growth that invites disease.
The Stadium Manager’s Choice
Precision Nutrition for High-Stress Stadium Environments.
Stadium environments are notoriously difficult. Poor light, restricted airflow, and high traffic. N31 gives you the control.
Reduce Mowing Frequency: Less top-growth means lower labour costs and less stress on the plant.
Eliminate Guesswork: A reliable 12-week feeding cycle. No more "hungry" yellowing.
Match-Day Ready: Maintain deep, consistent color that looks spectacular on camera.

The molecular formula for Isobutylidene Diurea (ISODUR®).
A masterpiece of organic chemistry designed to prevent leaching and volatilisation.
"Standard nitrogen is a fleeting moment. ISODUR® is a season-long commitment. It’s the most efficient nitrogen molecule ever synthesised for professional sports turf management."
The Gold Standard
Stop chasing growth cycles and start commanding them. Floranid® N 31 eliminates the peaks and troughs of nitrogen application, giving you months of elite-level colour and superior sward density from a single pass. When the pressure is on and the world is watching your surface, trust the slow-release technology that doesn’t quit.
