For turf managers, landscapers, pasture producers and turf farms, every kilogram of nutrient applied needs to deliver a return.
Rising fertiliser costs, weather uncertainty and increasing pressure to improve efficiency mean that getting more value from each application has never been more important. That is why Green Urea NV® and GreenTop K® are becoming popular choices for professional turf and pasture nutrition programs.
Both products are designed to help growers and land managers maximise nutrient efficiency, reduce losses and maintain healthier, greener and more resilient plant growth. They also provide a practical solution for situations where irrigation or rainfall cannot always be perfectly timed.
More nitrogen stays where it belongs
Nitrogen is one of the most important nutrients for turf, lawns and pastures, yet standard urea can lose significant amounts of nitrogen through volatilisation when left on the soil surface. Green Urea NV® uses proven urease inhibitor technology to slow the breakdown of urea, helping keep nitrogen available for plant uptake instead of being lost to the atmosphere.
One of the standout benefits is a reduction in nitrogen loss of approximately 25 per cent or more under many conditions. Australian field trials show significantly lower ammonia losses compared with standard urea. Trials conducted across multiple sites consistently demonstrated reductions in volatilisation losses, helping retain more nitrogen for productive growth.
“For a relatively small additional cost per tonne, growers can expect substantial benefits from reduced nitrogen losses and improved nitrogen-use efficiency. This is particularly important in current market pressures, costs and availability.”
- Hardin Smith, Rural Sales, Ace Ohlsson.
For landscapers maintaining premium lawns, turf farms producing saleable turf, or graziers looking to maximise pasture production, this means more of the fertiliser investment ends up feeding plants rather than escaping into the air.
Greater flexibility around rain and irrigation
One of the biggest challenges with traditional urea is the need for timely incorporation through irrigation or rainfall. Green Urea NV® provides much greater flexibility, allowing applications to be made up to 14 days before rainfall while reducing the risk of nitrogen losses.
This is particularly valuable for:
- Turf farms managing large application areas
- Landscapers working across multiple sites
- Sporting grounds and golf courses with limited irrigation windows
- Pasture producers relying on natural rainfall.
- The ability to apply ahead of weather events reduces labour pressure and improves operational efficiency, allowing work schedules to be managed more effectively.
Improved nutrient use efficiency
Because more nitrogen remains available within the soil profile, Green Urea NV® helps provide more consistent nutrient availability over an extended period. The result is stronger plant response, improved colour, sustained growth and better overall nutrient efficiency.
GreenTop K® complements this approach by delivering potassium, an essential nutrient responsible for stress tolerance, root development, wear resistance and overall plant health. Together, these products support stronger turf and pasture performance while helping maximise the effectiveness of every fertiliser application.
For professional turf managers, this can mean:
- Improved turf colour and presentation
- Better recovery from wear and traffic
- Enhanced drought tolerance
- Stronger root systems
- Greater seasonal consistency.
For pasture producers, increased nutrient efficiency can support stronger pasture growth, improved feed quality and better utilisation of applied fertiliser.
Ideal for surface applications and non-cultivated land
Many turf, pasture and landscape situations involve surface-applied fertiliser with little or no cultivation. Green Urea NV® was specifically designed to perform in these conditions, helping reduce losses associated with surface applications, organic matter, thatch layers, crop residues and pasture surfaces.
This makes it particularly well suited for:
- Newly established and mature lawns
- Sports turf and golf courses
- Turf farms
- Grazing pastures
- Hay and fodder production
- Areas where cultivation is impractical or undesirable.
- Long storage life and excellent value.
Another important advantage is storage stability. Green Urea NV® remains effective for at least 12 months when stored appropriately, giving customers greater purchasing flexibility and confidence in product performance.
With a small additional cost per tonne, the premium is relatively small when compared with the potential benefits of reduced nitrogen losses, improved nutrient efficiency and stronger overall performance. When more applied nitrogen remains available to plants, you can often achieve greater productivity from the same fertiliser investment.
A smarter choice for professional turf and pasture nutrition
Green Urea NV® and GreenTop K® offer a practical and proven way to improve fertiliser efficiency across lawns, turf and pasture systems. By reducing nitrogen losses, improving nutrient uptake, providing greater application flexibility and delivering reliable long-term performance, they help you get more value from every hectare.
