Precision application for consistent results
How precise fertiliser application improves turf health, prevents uneven growth, and maximises efficiency
Achieving healthy, high-quality turf requires more than just choosing the right fertiliser—it requires precise application.
Even small inconsistencies in how fertiliser is applied can result in uneven growth, nutrient imbalances, or an excessive build-up of fertiliser in certain areas. Ensuring accurate fertiliser distribution is essential for maintaining turf performance and optimising fertiliser use.
Why precision matters for turf health
Uniform nutrient distribution is crucial for fostering a consistent, healthy turf. Small variations in fertiliser application can lead to:
- Striping or streaking – Uneven nutrient distribution resulting in visible lines.
- Chequerboard effect – Inconsistent application patterns leading to irregular growth.
- Nutrient deficiencies – Under-application can leave turf vulnerable to stress and disease.
- Fertiliser burn – Over-application increases the risk of scorch and disease susceptibility.
Striping caused by misapplication
These issues can affect turf aesthetics and lead to long-term problems like soil imbalances or disease. That’s why precision in granular fertiliser application is critical for achieving the best results.
Techniques for consistent fertiliser application
To ensure consistent application and maximise the benefits of your fertiliser, consider these essential techniques:
Use of the right equipment
Choosing the right spreader is crucial. A spreader that provides consistent, uniform distribution ensures that nutrients are delivered evenly across the turf.
Demonstrations showed that the AccuPro 360ST provides a uniform spread pattern across its full application width.
While broadcast spreaders are commonly used, precision equipment like the AccuPro 360ST offers greater control over the spread pattern, reducing waste and preventing streaking or missed areas.
A competitor spreader delivered a less consistent spread pattern, with significant peaks and troughs.
Calibration is key
Regular calibration of your spreader ensures that it dispenses the correct amount of fertiliser per square metre. Improper calibration can lead to over- or under-application, both of which can harm turf health.
Take the time to calibrate your spreader before each application, and perform periodic checks to maintain accuracy.
Spreader settings: A guide, not a rule
Spreader settings serve as a reference point but should be adjusted to suit real-world conditions. Walking speed significantly influences spread width—slower movement can reduce the effective spread width, potentially causing striping.
For example, at 5 km/h, a spread width of 5 metres may reduce to 4.4 metres with a slower pace. Adjust settings dynamically to accommodate variations in walking speed, wind, and terrain.
Walking patterns: The key to consistent coverage
One of the most overlooked factors in granular fertiliser application is walking pattern consistency. Erratic movement or varying pacing can lead to uneven fertiliser distribution.
Walking speed not only affects the spread pattern but also influences the application rate.
Slower walking speeds can reduce the spread width and potentially cause striping, while faster speeds can widen the spread but may lead to over-application in some areas.
Maintaining straight, evenly spaced passes with proper overlap is essential for uniform coverage and accurate nutrient distribution.
Recommended Walking Patterns for Rotary Spreaders
Rotary spreaders, such as the AccuPro 360ST, distribute fertiliser in an arc, with higher concentrations at the centre and lighter coverage at the edges. Precise technique and attention to spreader settings are vital for achieving consistent results.
- Half-Rate, Double-Pass – ICL Recommended Approach
Apply fertiliser at half the recommended rate on the first pass. Follow with a second, overlapping pass to ensure full coverage and minimise the risk of over- or under-application. - Full-Rate, Single-Pass
More efficient but less precise, this method should only be used when time constraints are a priority. Ensure the spread width of each pass aligns correctly to avoid missed or over-applied areas.
Recommended Walking Patterns for Drop Spreaders
Drop spreaders, such as the AccuPro Drop Spreader, offer more controlled placement, ensuring fertiliser is applied exactly where needed without risk of spillage beyond the intended area.
- Full-Rate, Single-Pass
Apply fertiliser in parallel passes, slightly overlapping each to maintain consistent coverage. If multiple passes are necessary, alternating between parallel and perpendicular directions can further improve uniformity. - Overlapping Passes for Even Coverage
Overlapping your passes slightly during application can help ensure that no areas are missed, especially when using a spreader with a wider range. This will improve the uniformity of nutrient distribution and result in a more consistent turf appearance.
The benefits of precision granular fertiliser application
A precise granular fertiliser application delivers numerous benefits to turf managers, including:
- Improved Nutrient Efficiency: Fertiliser is applied more efficiently, reducing waste and ensuring the turf gets the nutrients it needs when it needs them.
- Consistent Turf Quality: By ensuring even nutrient distribution, precision application helps maintain a consistently healthy, vibrant turf.
- Cost Savings: Minimising over-application not only improves turf health but also reduces the need for additional fertiliser, leading to long-term cost savings.
- Environmental Responsibility: Precision application reduces the risk of fertiliser runoff, helping to protect local water sources and ensuring sustainable turf management practices.
Using the right technology
The AccuPro 360ST is designed specifically for turf managers who require the highest level of precision.
Its advanced features allow for accurate fertiliser distribution across a wide range of conditions, ensuring that your turf receives a consistent and even application every time.
With its easy-to-use controls and precise spread pattern, the AccuPro 360ST helps you optimise fertiliser usage, reduce waste, and achieve the healthiest turf possible.
Conclusion
Precision nutrition is not just about the fertiliser – it’s also about having the right equipment to apply it accurately.
By following the techniques outlined above and investing in reliable, precision-focused equipment, such as the AccuPro 360ST, you can ensure that your turf remains healthy, vibrant, and consistently performing at its best.
